There are places that feel pulled straight from the imagination, where mountains shift color with the weather and wind roars across a landscape so vast it feels prehistoric. Torres del Paine is one of those places. Granite towers rise like giant stone sentinels above turquoise lakes, lenga forests shimmer in the Patagonian sun, and glaciers creak like ancient doors. For many hikers, the Patagonia W Trek is the most achievable way to experience it all.
Named for the shape it carves across the map, the W is the park’s signature multi-day adventure: a winding route through the valleys, lakeshores and glacier-cut canyons that define Chilean Patagonia. It’s not the longest trail in the region, nor the most remote, but it may be the most unforgettable.
This guide brings together everything you need to know to confidently plan and enjoy the W Trek, whether you’re going guided or putting the logistics together on your own.
What Is the Patagonia W Trek?
The Patagonia W Trek is a four- to five-day route through the heart of Torres del Paine National Park in southern Chile. It connects three of the park’s most dramatic valleys: the Ascencio Valley beneath the famous Towers, the Frances Valley, and the route along Lake Grey toward the massive Grey Glacier.
The trail is challenging enough to feel like a real adventure, but accessible enough for intermediate hikers with strong fitness. Along the way, you’ll come across hanging glaciers, towering granite walls, alpine lakes, windswept ridges, and some of the best-equipped refugios in the Andes.
Who Is the W Trek For?
The W is ideal for intermediate to advanced hikers who want an immersive backcountry experience without committing to long navigational challenges or very remote terrain.
If you enjoy hut-to-hut hiking & dramatic vistas, and can handle a few hours of sustained uphill each day, you’re in the right place.
Travelers who prefer tent camping will find abundant opportunities as well.
How Long Is the Patagonia W Trek?
The route runs roughly 70 to 85 kilometers (43–53 miles), depending on variations and side trips. Most people hike it in four or five days, although some of our stronger hikers sometimes complete it in three.
The terrain has steady climbs, rocky pathways, sections of exposed shoreline, and the famous steep ascent to the Base of the Towers.
How Much Time Does It Take to Walk the W Trek?
Most hikers spend four days on the classic itinerary or five days if they prefer a slower pace or more time in the Frances Valley. Guided Torres del Paine hiking tours typically follow a five-day schedule that balances exertion and rest.
Where Does the Route Start and End?
The W Trek traditionally runs from Refugio Central (near the Las Torres trailhead) to Paine Grande, finishing with a catamaran ride across Lake Pehoé. The reverse direction is also possible, though it changes the feel of the daily climbs.
It can be done in both directions:
-
East to west starts at Base Torres.
-
West to east starts at Grey and finishes with the Towers.
Both directions are equally beautiful, but sunrise under the Towers is a major reason why we recommend most hikers to start in the East.
The Main Patagonia W Trek Route
The classic route follows a well-marked path through three key segments:
-
Ascencio Valley to Base Torres
-
Frances Valley and Mirador Británico
-
Paine Grande to Grey Glacier
Each segment delivers a very different kind of drama: glacial basins, roaring waterfalls, hanging ice, sweeping ridgelines, and some of the most iconic rock formations in South America. The W Trek never feels stale, and that’s part of why it’s so popular.
Variations Worth Considering
There are several optional variations if you want to add mileage or improve logistics:
-
Hike to Mirador Británico and back for more views of Frances Valley.
-
Extend past Grey to Camp Paso if you want wilder terrain and selfies on glacier overlooks.
-
Add a sunrise hike to Base Torres if your schedule allows. Trust us.
-
Reverse the route if refugio availability is limited.
Guides can help you choose the variation that matches your fitness, interest in photography, and preferred level of solitude.
Patagonia W Trek Stages: Day-by-Day Overview
Below is a breakdown of the classic east-to-west four-day itinerary.
Day 1: Torres del Paine Welcome Center to Base Torres
The journey begins with a steady climb through lenga forests and the windswept Ascencio Valley. As you move higher, the trail narrows, and the mountains begin to close in around you. The final approach is a steep ascent across boulders to one of the most impressive amphitheaters in the Andes: the classic view of the three Towers rising above a milky-green glacial lake.
Distance: approx. 20 km
Time: 7–9 hours
Most hikers return to Refugio Central or Refugio Chileno for the night.
Day 2: Refugio Central / Frances to the Frances Valley
This is the day when the W shape becomes obvious. You trace the shoreline of Nordenskjöld Lake, watching the mountains shift in color as sun and cloud drift across the sky. After reaching Camp Italiano, the trail rises into the Frances Valley, where avalanches sometimes crack off the hanging glacier above.
Many hikers continue to Mirador Británico, one of the most celebrated viewpoints in the entire national park, surrounded by an arena of jagged granite spires.
Distance: 16–20 km depending on how far into the valley you hike
Time: 6–8 hours
Sleep at Refugio Frances or Refugio Cuernos.
Day 3: Frances to Paine Grande
The third day is gentler, and it’s often the most contemplative portion of the trek. You walk beneath towering cliffs and above a chain of lakes that change from turquoise to deep blue depending on the weather. The trail rolls gently until you reach Paine Grande, which sits at the crossroads of some of the park’s most dramatic landscapes.
Distance: 13 km
Time: 4–5 hours
Spend the night at Refugio Paine Grande, famous for its incredible sunsets.
Day 4: Paine Grande to Grey Glacier and Return
Your final day leads toward the immense southern face of Glacier Grey, one of the principal tongues of the Southern Patagonian Ice Field. Icebergs often drift along the shoreline, and the wind can be powerful enough to feel like a living presence. Miradors along the route will deliver unforgettable views of the glacier’s fractured blue surface.
Distance: 22 km round trip
Time: 7–8 hours
End the trek with the catamaran back across Lake Pehoé. It’s a fittingly scenic finale.

What’s the Best Time to Hike the Patagonia W Trek?
The main season runs from October through April, which corresponds to late spring, summer, and early fall in Patagonia. Weather here is famously unpredictable, but each month offers different benefits.
-
October–November: Wildflowers, energetic waterfalls, fewer crowds.
-
December–February: Warmest temperatures and the longest daylight.
-
March–April: Crisp air, autumn colors, quieter trails.
Winter trekking is possible with special permissions and full mountaineering gear. For most hikers, however, the traditional season is the safest and most enjoyable window.
How Difficult Is the Patagonia W Trek? Can Beginners Do It?
The W is not technically difficult, but it is physically demanding. Daily distances often range from 12 to 22 kilometers, and the trail includes steep climbs, uneven rock, and exposure to strong Patagonian wind.
Fit beginners who train beforehand can absolutely complete the trek. The most important factors are preparation, appropriate clothing, a steady pace, and realistic expectations about Patagonia’s weather.
Where Should I Stay Along the W Trek?
Most hikers stay in a combination of:
-
Refugios – Hostels with beds, meals and heating
-
Campsites – Platforms or grassy tent areas with bathrooms
-
Full-service camps – Tents already set up for you
Popular options include Chileno, Central, Cuernos, Frances, Paine Grande and Grey. These must be reserved well in advance, especially in high season. Guided treks simplify this process because outfitters secure accommodations ahead of time.
What Will I Eat on the Trek?
Refugios offer hearty meals such as soups, pasta, chicken, rice dishes and plenty of bread. Breakfast often includes eggs, oatmeal and fruit. If you camp, you can purchase meal packages or bring your own dehydrated food. Water is generally safe to drink directly from streams, though many hikers prefer to filter it.
How Safe Is the Patagonia W Trek?
Torres del Paine is considered very safe. There are no dangerous animals on the trail, and navigation is straightforward. The primary risks are wind, rain, hypothermia, dehydration, and ankle or knee injuries. Weather can change rapidly, so carrying proper layers and paying attention to ranger advice is essential. Guided groups benefit from expert leadership and real-time decision making.
Can I Bike the Patagonia W Trek?
The W Trek is not a biking route. Regulations prohibit bikes on the hiking trails due to erosion risk and narrow terrain. However, the park offers bike-legal gravel roads and scenic cycling loops that you can enjoy before or after your trek.
Do You Need a Guide for the Patagonia W Trek?
Hiking without a guide is completely allowed, but many travelers prefer an all-inclusive guided W trek tour because it removes the stress of bookings, transportation, meals, and weather decisions.
A local guide can also enrich your trip with stories of the region, insights into the geology and wildlife, and a deep understanding of how to read Patagonia’s mercurial winds.
Travelers new to multi-day trekking often find that going with a guide allows them to focus on the landscape instead of logistics.
Frequently Asked Questions About the Patagonia W Trek
Do you need permits for the W Trek?
You don’t need a formal hiking permit, but you must reserve every night in refugios or campsites before entering the park. Rangers will check your bookings at multiple checkpoints.
Can you drink the water?
Yes. Patagonia’s water is famously clean, especially when drawn from fast-moving streams. Many hikers drink it untreated, though filtering is recommended for peace of mind.
Are hiking poles necessary?
They aren’t mandatory, but they are incredibly helpful during steep ascents and descents, as well as when wind gusts test your balance. Many guides consider them essential for Base Torres and Frances Valley.
How far in advance should I book?
For peak season, bookings often fill six to nine months in advance. If you are flexible or visiting in October or April, it’s easier to secure last-minute spots.
Is solo trekking allowed?
Absolutely. Many hikers complete the W alone, on self-guided tours. The trail is well marked, refugios are friendly, and there are always other trekkers nearby. Still, solo hikers need to prepare for fast-changing weather.
The Patagonia W Trek Awaits
The W Trek is more than a journey across a map. It is a walk through one of the last great wildernesses on Earth, where granite towers glow pink at sunrise, and the wind carries the sound of distant glaciers shifting in their sleep. Whether you come for the challenge, the photography, the solitude, or the companionship of fellow trekkers from around the world, the W delivers an experience you’ll remember for decades.
If you want to deepen your connection with the region, traveling with a local guide can transform the trek into something richer. Their knowledge of the land, its stories, and its rhythms brings Torres del Paine to life in a way few guidebooks can match.
Whenever you choose to go, lace your good boots, pack your layers, and step into one of the most breathtaking landscapes on the planet.
