19 Things to Know Before Hiking the W Trek in Patagonia’s Torres del Paine in 2023

So you’re interested in hiking the W Trek in Patagonia – one of South America’s most famous trails. The W Trek zigzags through the heart of Chile’s iconic Torres del Paine National Park, a land where the summits form stunning granite monolith towers and the lakes glisten a breathtaking turquoise blue. The trek is named after the W-shape it forms on a map, running along the base of the iconic mountains before doubling back into the Valle Francés (‘French Valley’) at the very heart of the reserve.

This detailed guide will run through all the ins and outs of hiking the W Trek. It will cover the best time of year for hikers to visit this wild part of Chilean Patagonia, some challenges you can expect to encounter, top trip highlights, what gear you will need, how long you may spend in the wilderness, and much more. Happy exploring!

My experience hiking the W Trek

I’ve trekked extensively throughout the Andes, from the dizzying heights of Machu Picchu to the impressive glaciers of Argentine Patagonia, and have learned powerful life lessons from my adventures. However, I still remember the W Trek as one of the most amazing mountain adventures I have taken. There’s a reason why it’s the most famous hiking trail in Patagonia. The scenery you’ll enjoy along the way is second to none – imagine jagged mountains that resemble massive shards of ice, milky mountain lakes, and the rolling Patagonian Steppe in the distance. 


A personal highlight of the W Trek was the approach to Grey Glacier, which feels like one of the most untouched parts of Torres del Paine. The path to Grey Glacier along Grey Lake is stunningly beautiful and poses a nice challenge as you trek amongst chiseled sculpturesque mountains. Adding to the physical beauty of it all, the hiking route is fantastically well-organized with designated camp / hut sites that boast gorgeous views of the national park, the trekking season is long, and wonderful local guides are available. I highly recommend you experience hiking the W Trek for yourself.

1. An introduction to Chilean Patagonia

Chilean Patagonia is one side of the greater region of Patagonia. Altogether, it encompasses a whopping 400,000 square miles (that’s over a million square kilometers!) of land at the southern end of South America. It’s a diverse place, rolling from seemingly endless steppes inhabited by unusual Welsh-speaking farming communities to the jagged tops of mountains like the Fitz Roy and the Torres del Paine.

Ever since the first Spanish conquistadors started coming here in the 1500s, Patagonia has been seen as a land of myth and majesty. Open and vast like nowhere in Europe, it wowed explorers with calving glaciers and penguin-spotted islands, mirror-like alpine lakes, and whale-filled oceans. Today, the awe-inspiring nature of the region is still very much intact and trekking here is seen as a bit of a rite of passage a la the Himalaya.

Chilean Patagonia begins roughly 500 miles (805 kilometers) south of Santiago, the capital, and then arcs around the whole of the edge of the continent before finishing at the icy channels of the Tierra del Fuego archipelago. It’s all pretty wonderful, but most agree that the zenith is the Torres del Paine National Park, which is where you’ll be doing the W Trek.

2. Where is the W Trek?

The W Trek leads you to the most famous part of Chilean Patagonia: The Torres del Paine. They’re a trio of incredible granite tower peaks that look like daggers shooting straight out of the earth. At their closest point, the three towers are just 12 miles (19 kilometers) from the Argentina border. The nearest main town is Puerto Natales, Chile. More generally speaking, the W Trek takes you down to the ice-capped, snow-dusted ends of the continent, less than 400 miles (645 kilometers) from Cape Horn. It’s truly a wild part of the planet you must see!

3. The history of the W Trek and the Torres del Paine National Park

Arguably the most famous corner of Chilean Patagonia, the serrated tops of the mighty Torres del Paine massif became the centrepiece of their own national park back in 1959. But you have to go back almost 80 years more to discover the moment when the region first entered the limelight.

Yep, Scottish travel-writing pioneer Lady Florence Dixie blazed a trail here during her South American travels in the late 1880s. Her prose recalls “three tall peaks of a reddish hue” stood before plains of ripe berry bushes and grazing guanacos.

Her descriptions piqued the interest of others. Finnish geologist Otto Nordenskjöld took a break from his polar explorations to visit the region in the 1900s. Then came the missionary-mountaineer Alberto María de Agostini en route to his epic crossing of the Southern Patagonian Ice Field.

It wasn’t until the end of the 1950s that the region was designated an official national park by the Chilean government. It was originally known as Grey Lake National Tourism Park but was subsequently given its modern name in the 1970s, the same decade it was dubbed a prestigious UNESCO World Biosphere Reserve.
It was also the 1970s that saw the formation of the famous trails. That was spearheaded by a team of local rangers in conjunction with British explorer John Garner (who now has a pass named after him in the range). They laid the foundations of the now-iconic circular route that encompasses the whole massif, including the W Trek section itself.

4. Highlights of the W Trek


If you’re looking to be wowed by the sheer majesty of hiking in Chilean Patagonia, then yes, the W Trek is most certainly worth it. This relatively low-altitude trek takes you through areas of the national park that are widely considered to be the most incredible places in Patagonia. In a region that’s beset by ice fields and soaring peaks, that’s really saying something! 

The W Trek requires a commitment of about 4-5 days of hiking, on average. What’s great is that there is something special to see on every single day of the journey. Views abound from start to finish and there’s always another W Trek highlight to look forward to. The most impressive parts of the trek are:

  • The French Valley & Cerro Paine Grande – See the spectacular summits of Cerro Paine Grande, the tallest peak of the Cordillera Paine mountain range in Torres del Paine National Park, up close as you trek into the French Valley. The French Valley is a hidden cleft in the Andes that’s topped by a hanging glacier and dashed with gnarled beech forests.


  • The Base of the Towers – you will either finish or begin the trek at this stunning location with a turquoise lake set before the iconic Torres del Paine granite spires themselves. The lookout point encompasses three sheer mountains before a milky alpine lake. This is the scene that is the infamous image of the W Trek. 


  • Mirador Britanico There are numerous lookout points within the French Valley, but we’d say the Mirador Britanico trumps the lot. Stand on this slab of rock to survey an amphitheater of cathedral-like mountains that descend into forests of Antarctic beech trees filled with finches and woodpeckers.

  • Los Cuernos – A set of twisted mountains dominating the northern view for much of the hike. A colossal cirque of peaks all tangled together, the Los Cuernos form the very heart of the Torres del Paine massif. Look up to spy out summits named things like The Blade, The Sword, and the Shark’s Fin.


  • Grey Glacier – This colossal ice field with calving sheets of frozen water could be one of the most awe-inspiring things you encounter on the W Trek. It is the largest glacier in the Torres del Paine National Park. Just one of the many tongues of frozen water that cascade down from the great Southern Patagonia Ice Field, Grey Glacier is either the grand finale or the starting point of the W Trek. It’s everything you imagine of a South American ice cap, sporting 98-foot high (30 meters) walls that rise suddenly from the turquoise waters of Lake Grey.


  • Pehoé Lake – This many-armed body of water rolls out to the south of the W Trek path. You’ll see it on multiple days, but there’s one epic photo spot that frames the twisted Los Cuernos mountains above a mirror-like dash of water.

  • The wildlife in Torres del Paine – Of course, you cannot forget the park’s incredible fauna! You will undoubtedly encounter a diverse range of wildlife on the W Trek. One of the most common mammals you will spot will be the ubiquitous guanacos, which are related to llamas and vicuñas. You may also see Magellanic woodpeckers, Patagonian gray foxes, Andean condors, or even caracaras (a unique-looking bird of prey). Even more elusive are the pumas and the endangered and rare Chilean Huemul, or South Andean deer.


5. How long is the W Trek? How many days are needed?

The distance of the W Trek is approximately 55 miles (88.5 kilometers) long. One of the great things about this hiking route is just how versatile it can be. It’s easy to chop, change, and add to the W Trek itinerary so you’ll find everything from 4-day treks to 7-day ultimate treks on the menu.

There are many different distances reported by various sources for the W Trek. The below is what I have personally tracked via GPS while hiking the East to West route.

Day 1 – Central Sector to Central Sector (Base Torres Hike)

  • 13.5 miles / 22 kilometers

Day 2 – Central Sector to Frances Sector

  • 11.5 miles / 18.5 kilometers

Day 3 – Frances Sector to Paine Grande (including Mirador Britannica Lookout)

  • 15 miles / 24 kilometers

Day 4 – Paine Grande to Grey Mountain Refuge

  • 7.5 miles / 12 kilometers

Day 5 – Grey Mountain Refuge

  • 7.5 miles / 12 kilometers

You can do the trail in different directions. There are ways to skip one leg of the journey and add on extra excursions. So long as you follow the basic idea of a W-shaped route through the Torres del Paine park and include a trek into the stunning French Valley along the way, you can rest assured that you’ll see the Patagonian national park’s highlight attractions. 

6. Elevation and terrain on the W Trek

The pinnacle of the W Trek reaches 2,788 feet (850 meters) above sea level. Now, that might sound positively low for veterans of Everest Base Camp, Mount Kilimanjaro, or the Inca Trail – and it is. However, where this trek gets tricky is in elevation gain and loss and the daily distances. Some sections of the W Trek see hikers clock up altitudes of over 2,000 feet (610 meters) in just a few hours, only to lose it all again that afternoon as they head to the rest site for the night. You’re likely to notice this most after the hike to the base of Las Torres, which is followed a few days later by the ascent into the French Valley.


The good news is that there’s zero technical climbing on the W Trek. The trek is on a mix of well-maintained paths, packed mud, loose gravel, and stones. There are some parts where you may need to navigate wet rocks, low streams, and cable bridges, but there’s nothing overly challenging on the route itself in terms of terrain.

7. Is the W Trek difficult?

The W Trek multi-day hike isn’t a cinch, but it’s also not on the same level of difficulty as other world-famous hikes such as Mount Kilimanjaro or Everest Base Camp. So how hard is the W Trek in Patagonia’s Torres del Paine? Well, there’s no technical expertise needed and you don’t have to acclimatize. The trail is well-marked and maintained for a majority of the route. I’d say one of the the biggest challenges is the unpredictable weather, which can change from snow to heavy rain to blazing sun in just a matter of hours. In addition, Torres del Paine is known for its extreme winds which can reach up to 100 MPH. 


The W Trek also packs a lot of walking into single days. For comparison, you are asked to hike between 6 to 8 miles per day on average on an Inca Trail tour. However, on the W Trek, you can expect to hike between 7.5 miles to 15 miles per day depending on how your adventure is structured. I highly recommend a training plan that builds in long distances (over 10 miles per day) and consecutive day hikes.

8. Preparation for the W Trek

We’ve already mentioned how the W Trek isn’t up there with Kilimanjaro and other high-altitude expeditions. Most trekkers of decent fitness level should be able to complete it with a solid training schedule beforehand. That said, the days are long on this one – some pack in up to 10 hours of hiking across tough terrain that can get tougher when the weather changes.

For that reason, we’d say a good program of regular exercise starting around 12 weeks prior to the start of your hike is always a good idea. Begin with local walks of two or three hours and short runs of just a few miles each. By six weeks out, you should be able to up your runs to three miles and complete a hike of seven to nine continuous hours. With three weeks to go, try to double your number of runs and do weekly hikes of at least seven or nine hours each. I also recommend that you begin doing consecutive day hikes at this time and ensure you are wearing a pack with the same weight you will bring with you on the trek. Resistance training can also work wonders for muscle fatigue and recovery, something that’s often an issue with such long days on the W.

9. When is the best time of year to do the W Trek?

The seasons can be very unpredictable this far south in Patagonia. As a general rule, summer (November to March) is better for trekking, making it the peak season for hiking the W Trek in Torres del Paine. That’s because it’s warmer, with midsummer temperatures typically between 43-63 degrees Fahrenheit (6-17℃), and there’s less rain (average of just 4 millimeters each month).

However, it’s not totally clear cut that the summer season is the best time to hike the W Trek. It all depends on your preference and the type of experience you’re looking for. There are way more people hiking the trail so the W Trek lookout points are busier and the mountain huts more expensive. Additionally, high summer winds can spoil a hike in Patagonia so you’ll have to be ready to change plans if the gusts get up to over 80 mph (130 kph) or so.


Autumn (April to early June) is a good alternative to the main summer trekking season. The upsides include fewer hikers and beautiful colors on the Patagonian Steppe – think pale yellows, deep oranges, and muted browns rolling out from the base of the mountains. However, there is usually more rainfall and the temperatures at night get low. 

Spring (September to November) is another popular time to hike the W Trek but this season can bring the risk of snowfall. This means you’ll need to pack extra thermals.

Winter (late June to August) trekking through the Torres del Paine is mainly closed due to snowfall. The only path that’s open is the day hike to Torres del Paine Base, but that too is regularly closed because of snow. So the best time to visit will depend on you.

For the 2023 season, we are offering trips now through April 30, 2023.

10. What do I need to pack for the W Trek in Patagonia?

What you pack for your W Trek trip will depend on when you decide to visit Torres del Paine to hike the trail, but try packing as light as possible. Travelers in the high season (summer and autumn) won’t need as much thermal gear as those visiting in the low season (spring and winter), when there’s a bigger risk of snow and sub-zero temperatures. That said, every hiker on the W Trek should have a good thermal under-layer, a fleece, and waterproofs for the upper and lower. The weather can be pretty wild and unpredictable, even in the height of summer, so it’s a good idea to bring multiple layers to wear.

When it comes to trekking equipment, there are some must-haves: sturdy walking boots, a good set of trekking poles, a high-volume and lightweight water bottle and/or reservoir, sunscreen, and a reliable waterproof trekking backpack. Depending on how you choose to do the trek, you may also need camping equipment and a sleeping bag. Note: when booking with us, sleeping bags will be ready for you in a mountain hut or tent at each stop, and you are also provided a ‘welcome kit’ that includes a sleeping bag liner and personal towel.

Also, drinking water is not treated at huts/campsites along the trail. Many hikers feel comfortable drinking the water along the route (including from rivers or streams). But, if you prefer additional protection and peace of mind, you can certainly bring your own portable water filter (e.g. Katadyn BeFree, LifeStraw, Grayl, Sawyer Squeeze, etc.). Some of these systems only weigh a few ounces!


Some hikers will go for a porter service on their W Trek trip to help carry baggage and equipment. That’s an optional extra with most providers. It can be expensive and I’d argue it’s not necessary because the W Trail isn’t the most challenging route out there.

My team at The Explorer’s Passage makes it easy for trekkers who plan their travels with us. Because the requirements for the W Trek change with the seasons and the sort of trek you go for, we can provide our guests with a full packing list so they’re fully prepared – just ask us!

11. Accommodations: Where to stay on the W Trek

There are two options when it comes to accommodations on the W Trek: camping tents or refugios. What is a refugio? It’s the local name for a refuge or shelter that’s essentially a mountain hut, lodge, or guesthouse that offers dorm-style accommodation. Refugios are rustic but comfy and typically have warm communal areas with dining halls where you can meet and mingle with other travelers on the W Trek. The best way to secure your place in a refugio hut is to go with an organized tour, as beds sell out fast on this ever-popular route.

Mountain hut and tents surrounded by Patagonian mountains

For the most part, the campsites on the W Trek are of very high quality, at least for true backcountry camps. They’re well equipped with all the things that trekkers might need, and even have extras that you could only dream of in the far-flung basecamps of other major trails. Take the site at Paine Grande for instance: it has hot showers during a few designated hours post-trek, a canteen and bar, and even pay-as-you-go WiFi.


The good news is that these accommodations are all located in the same places, or at least very close to each other. That means you won’t have to rearrange the route you hike to find the level of accommodation you’re after. The W Trek is punctuated with a host of rest areas and the conventional plan of the hike makes use of six or seven of these along the way. Let’s take a closer look at each rest site:

  • Central Sector – The Central Sector, also sometimes referred to as simply Central Camping, is the base of operations on the eastern side of the W Trek. It’s often used as the start point or end point of the whole journey and is one of the most developed sites of the lot. Tents here are pitched on purpose-built wooden platforms, there are hot showers, and designated picnic tables. Those wanting a touch of luxury can also swap out the canvas for a stay in the adjoining Refugio Las Torres or Hotel Las Torres.
  • Chileno – The second of the major Las Torres Patagonia sites on the route is wedged into the narrow valley that runs north to the base of the Las Torres themselves. It’s a pitstop for before or after seeing arguably the greatest vista on the W Trek and the location is one to match – scenes of snow-capped peaks and cascading pine woods dominate on both sides. The site is much like the Central Sector, with tents pitched on wooden plinths and hot showers on offer. Refugio Chileno is the hut option here. It’s a quality lodge with a fantastic outdoor area by a roaring river.
  • Los Cuernos – You’ll be greeted with sweeping 180-degree views of glimmering Lake Nordenskjöld when you enter the Cuernos campsite. Set on a soft slope right under the twisted tops of the Los Cuernos massif itself, this spot often marks something around the midway mark for through trekkers. In true Las Torres Patagonia style, it’s well appointed, with private tent pitches on timber platforms, along with extras like an onsite bar and a snack kiosk.
  • Francés – Remember when we said that the French Valley was one of our top highlights on the whole W Trek? Well…the Francés campground is the gateway to it all. Just two miles (3.2 kilometers) to the west of Los Cuernos, it’s an alternative midway option for hikers wanting to enter that secret Shangri-La of the Andes. It’s also just as comfy as the other sites listed here, complete with hot showers and glamping dome tents.
  • Italiano – This campground on the main course of the W Trek is a free-to-camp alternative at the base of the French Valley. Because it’s free, don’t expect the same amenities and frills as in the sites on the W Circuit. The basics are all taken care of: Running water, toilets, and a cooking shelter. There’s also an option to drop bags here for the up-and-back excursion into the French Valley.
  • Paine Grande – There’s a pretty slick lodge at the Paine Grande camp on the edge of Lake Pehoé that some people use as the first point of call on the W Trek. It’s got private rooms and dorm options. The adjoining campsite has space for up to 260 campers, a covered cooking area, and gender-specific hot water showers. Don’t miss the onsite Paine Grande Bar here – it’s a chance for a pre- or post-trek drink overlooking the serrated Paine Grande Massif.
  • Grey – Grey campsite marks the western end of the W Trek and, as such, is an important start point, not to mention connecting point for those looking to join with the larger O Trek. The lodge here is one of the best on the trail. It’s got 60 beds over a series of mixed dorms and a cozy lounge-restaurant to enjoy after dark. The campground has room for 120 people and offers a covered cooking space and shared toilets. There’s paid WiFi, if you need it.


Since each campground site is run by one of three companies and itineraries often require a separate reservation, booking accommodations can be a chore. It doesn’t have to be though! The Explorer’s Passage makes visiting Torres del Paine easy. Book your trip to Patagonia with us and let us take the stress out of planning so you can focus on hiking the W Trek. Also, all meals are included from the start of the hike to the finish with us.

12. W Trek permits

In planning this journey, you may ask yourself “Do I need a permit for the W Trek?” Although you’ll need an entrance ticket to enter Torres del Paine National Park, there’s no official permit system for the W Trek a la Machu Picchu. There are, however, regulations on the number of trekkers that are allowed to stay in the park’s campsites and huts. That acts as a sort of de facto limit on the number of people who can do the trek, governed mainly by who was quick enough to book their accommodations. 

My advice? Start planning early to avoid disappointment. Better yet, plan to travel with us now through 30 April, 2023 and our experienced team will take care of all the important details for you, including campsite bookings.

13. Getting to the start of the W Trek

Most people start the W Trek hike with an organized bus transfer from the city of Puerto Natales to Torres del Paine National Park.


Your journey to the trailhead of the W Trek will depend on which direction you will be hiking it: either from east-to-west, or vice versa. At The Explorer’s Passage, we recommend east-to-west, primarily because you get the hardest day of hiking (to and from Las Torres Lookout Point) out of the way on the first full day, when your legs are still fresh. However, some prefer to save the view of these granite towers as a reward for the final day, so they start the journey in the west and head east. As with all adventures, there are pros and cons to each option!

  • To hike the W Trek from east to west, you will get off the bus at the park office at Laguna Amarga, then head to the Central Sector.
  • To hike the W Trek from west to east, you can get off at the Pudeto stop and catch the catamaran across Lake Pehoé to the refugio at Paine Grande. There are boat departures throughout the day, but be sure to check the schedule before you depart because they can change at short notice.

All of the above trips can be done from Punta Arenas, but expect transfer times to the trailhead to be in the region of five to six hours, instead of a two to three hour bus ride from Puerto Natales.


14. Sample W Trek 4-Day Hike itinerary

As noted in the prior section, at The Explorer’s Passage we recommend hiking the W Trek from east to west. Below you will find a sample itinerary for this option (visit our W Trek trip page to download the full detailed itinerary):

  • Day 1: Puerto Natales to Torres del Paine National Park – After breakfast at your hotel in Puerto Natales, you will have the morning to explore the town a bit more. Later, you will travel by bus to Torres del Paine National Park. Enjoy dinner in the Central Sector as the excitement builds for the days ahead, where you will have the rare privilege of exploring one of the planet’s most striking national parks!
  • Day 2: First Day of W Trek (Las Torres Lookout) – Today, you will start early and begin your hike of the W Trek – one of South America’s most famous trails. Today’s destination is the iconic Las Torres Lookout Point! During the first stretch, you will walk through the pampa, cross the Ascencio River, and then hike up to Los Vientos Mountain Pass, where you will enjoy amazing views of the valley and lakes. You will continue your journey to the Chileno Mountain Refuge, and then go deep into a lenga beech forest up to La Morrena, where the hardest part of the day’s hike begins. From there, you will follow a rock trail to the spectacular Las Torres Base Lookout Point. Later, you will return to the Central Sector to have dinner and rest.
  • Day 3: Second Day of W Trek (Nordenskjöld Lake & Francés Sector) – Today is your 2nd full day of hiking the W Trek. You will walk along the shores of Nordenskjöld Lake, below the peaks of Almirante Nieto and the striking Cuernos del Paine. During the hike, you will enjoy magnificent views of Los Cuernos, hanging glaciers, lakes, and the abundant vegetation and wildlife. You will have dinner and sleep in the Francés Sector.
  • Day 4: Third Day of W Trek (French Valley) – This day features one of the most memorable portions of the W Trek: the Valle Francés. You will start early with a light hike to the Italiano Campsite. From there, you will progress through the woods up the Francés River Valley. You will continue to the Francés Lookout Point, where you will enjoy one of the most breathtaking views of the trek: the view of the valley framed by the Paine Grande, Catedral, Hoja, Máscara, Espada, Aleta de Tiburón, and Cuerno del Norte mountains. The landscape will undoubtedly leave you speechless! Later, you will begin the descent to the Paine Grande Sector for the evening.
  • Day 5: Fourth Day of W Trek (Grey Glacier & Pehoé Lake) – On this day, you will reach the third major milestone of the trek, the incredible Grey Glacier. The trail goes around the Paine Grande, the highest peak in the mountain range (3,050 m), with incredible views of its hanging glaciers. Walking amidst Antarctic beech trees (ñirre), Dombey’s beech (coigüe), and Chilean firebush (notro), you will reach the first lookout point of Grey Lake, where you will spot floating pieces of glacier. You will continue hiking north towards the imposing view of Grey Glacier to reach the Grey Mountain Refuge. Then, after fully taking in the sights of the massive glacier, you will return to the Paine Grande Sector and board the catamaran that will take you across Pehoé Lake to Pudeto station. There, you will take the bus back to Puerto Natales.
    • Note: we can arrange optional add-on excursions in the Grey Glacier area if you are interested: kayaking (~3 hour activity) and/or ice hiking (~5 hour activity). These activities will require more time on your itinerary, and potentially an additional overnight in the park.

Hiker with outstretched arms on a cliff by a glacial lake and Las Torres granite tower peaks on the W Trek in Patagonia

If you prefer to hike the W Trek from west to east, culminating with an up-close encounter with the iconic towers themselves, here is a sample itinerary:

  • Day 1: Puerto Natales to Torres del Paine National Park  You can get an early pickup in the towns to the south of the Torres del Paine National Park and then a transfer north to the Hotel Lago Grey. From there, a ferry whisks you across Grey Lake (Lago Grey) with the icy tongue of the colossal Grey Glacier looming ahead. This is your first chance to catch a glimpse of the famous Torres massif highlight, with a broadside of the twisted tops of the Cerro Paine Grande rising to the east. Your destination is the campsite and hut at the base of the Grey Glacier, a starting point for the west-to-east W Trek route. An alternative option here is to catch the catamaran ferry across Lake Pehoé (Lago Pehoé) and then walk to the Grey Glacier lodging from there.
  • Day 2: First Day of W Trek (Grey Lake & Glacier)  Your W Trek hike starts by skirting the milky waters of Grey Lake going southwards. This is right beneath the Cerro Paine Grande and the Paine Horns, which are some of the most famous mountain summits in South America. Before setting off, I’d recommend taking some time to visit the Mirador Glaciar Grey. It adds a few hours of walking but offers a sweeping panorama of the point where the ice meets the frigid waters, with the potential to see calving ice sheets.
  •  Day 3: Second Day of W Trek (Paine Grande to French Valley)  For many, this day is the highlight of the whole W Trek. The path bends eastwards and north from your second campsite, taking you deep into the heart of the Torres del Paine National Park. The first step is the trek along the south side of the massif to the Italiano campsite. You can leave your main bags there for the expedition into the French Valley. Then, take the north spur into that famous cleft in the Andes, which soon becomes a lush land of twisted pine trees and meadows beneath the hanging French Glacier. If the group is walking well, the aim will be the jaw-dropping Mirador Británico at the end of the valley, all before a return to the Italiano campsite.
  •  Day 4: Third Day of W Trek (Nordenskjöld Lake and Frances Sector) – You’re now back to skirting the southern edge of the Torres del Paine. Head east from the Italiano campsite and join the path that circles Nordenskjöld Lake (Lago Nordenskjöld). It will take much of the day to link up to your next W Trek overnight spot, but there are some fantastic lookouts along the way. They’ll put the high peaks of the Torres just behind and the rolling tundra of Chilean Patagonia in front, not to mention the placid waters of numerous alpine waters in the foreground.
  • Day 5: Fourth Day of W Trek (Las Torres Lookout) – After an early morning start, you will begin a tough uphill ascent through the craggy easternmost valley of the Torres massif. It’s steep but opens the way to the Mirador Las Torres, which is surely one of the most unforgettable viewpoints on the planet! There, you’ll see the three jagged peaks that give this region its name and reputation, jutting straight up from pearly blue waters. You should finish with photos around mid-morning, because you’ll be descending back down to the Central Sector and then to Laguna Amarga to board a bus back south to Puerto Natales (or Punta Arenas, for a longer journey).

These sample itineraries are just a start and the opportunities are endless. Regardless of whether you’re traveling solo or in a group of any size, our expert Adventure Consultants will craft extraordinary itineraries for your private travel needs.

15. The 5-Day W Trek Circuit

The W Trek circuit is often completed in four full days of trekking. However, approximately 30% of our travelers elect to do it in five days and spend a night at the Grey Mountain Refuge by Grey Glacier, either camping or in huts.

With this 5-day hike option, the fourth day’s 13.5-mile (22-kilometer) hike is essentially split in half and shared between Days 4 and 5: from Paine Grande Sector to Grey Sector on the fourth day and then back to Paine Grande Sector the next day to catch the catamaran across Lake Pehoé.

Trekkers who select the 5-day option and spend a night in Grey Sector also have the opportunity to take an ice trekking excursion on Grey Glacier (with crampons and ice axes) or go kayaking in Grey Lake, with amazing views of the massive glacier. Both of these adventure activities are offered multiple times per day, and are a great way to complement a trek in Torres del Paine.

16. W Trek Express

Most experts agree that this is the single most incredible trek in the whole of Patagonia, both on the Argentinian and Chilean sides of the border. However, not all travelers have the time to complete the entire adventure, which is why a more condensed version of the W Trek is now on the menu…

Cue the W Trek Express route. This cuts down your travel time by one day but still ensures you get to see all the legendary parts. Your travel from Puerto Natales to Torres del Paine will take place on the same day that you begin trekking. It runs east to west, starting with the dramatic outlook over the Torres del Paine on an up-and-back route. Day two skirts the top end of Nordenskjöld Lake beneath the amazing Los Cuernos peaks. Day three is another there-and-back hike into the heart of the French Valley before a final day that whisks you across Lake Pehoé to be collected.

The whole Express W Trek can be self-guided or guided and done with hut accommodation or camping. One other important piece of information to note, since the Paine Grande hut does not typically open until October 1 each year, then your only option to do the W Trek trail in September is via the Express route.

17. Alternative routes to the W Trek (O Circuit and Q Circuit)


The W Trek may be the most popular trail in Torres del Paine but it certainly isn’t the only walking route that will let you experience this awesome corner of Chilean Patagonia. Usually open from November to April, there are also two route extensions that take you counterclockwise on the trail but promise to whisk you even higher into the clouds as you explore the mountains and glaciers. They are:

  • The O Circuit (6-10 days) – Also known as the Paine Circuit, the O trek is the full circuit around the Cordillera del Paine mountains within the national park and includes the W route. It’s definitely a tougher and longer route, but its lesser traveled 74 miles (119 km) of pure Patagonian wilderness will take you to the heights of the John Gardner Pass at about 4,000 feet (1,219 m) above sea level. O Circuit trail highlights you’ll see include the reflective Lago Paine, a mesmerizingly turquoise lake, and the mountains from
    the northern section of the park.
  • The Q Circuit (7-11 days) – The Q Circuit is the longer version of the O Circuit. The Q route includes one extra day of trekking past Lake Pehoé. This one’s for the most dedicated of trekkers who have the most time (and money) to spare. 

If you have more time to spare and are up for an extended trek, definitely try out one of the treks above.

18. Where to go after the W Trek

You’ve got a few options for onward travel once you’ve finished the W Trek. The most obvious and popular place that hikers return to is Puerto Natales. Many trek packages even include a drop-off back in that town, which has become a bit of a buzzy outdoors hub in recent years, touting craft beer emporiums and wine tasting establishments. Puerto Natales also happens to be the best base for launching boat trips through the stunning fjords of Chilean Patagonia, including to the far-flung Tierra del Fuego for penguin watching and the Serrano Glacier a little closer by.

You might also want to use this opportunity to cross over into Argentinian Patagonia. The W Trek takes you very close to the border and there are regular buses that make the trip up to towns like El Calafate (five hours) and El Chaltén (nine hours) from Puerto Natales. It’s a top option for continuing your adventures through the Andes, opening up hikes under the Fitz Roy (arguably the most famous mountain in Argentina) and visits to the Perito Moreno Glacier (a UNESCO site that showcases huge chunks of ice peeling off a glacier tongue).

19. Visas for Chile

There’s a long list of 90 countries that get visa-free access to Chile, including virtually all of the European Union, the United Kingdom, and the United States. That means administrative work at the border or prior to departure shouldn’t be too much of an issue if you’ve got your heart set on the W Trek. Notable exceptions include Australian citizens, who are no longer charged a hefty reciprocity fee when they enter but do need to go through the process of pre-applying for a single- or multiple-entry visa. All travelers should have at least six months’ validity left on their passport before traveling.

So there you have it, a comprehensive guide to 19 things you should know before hiking the W Trek in Chilean Patagonia!
