What is the Torres del Paine W Trek?

Heading to Patagonia? Or already in South America? You've no doubt been advised more times than you can remember to explore the famed W trek of Torres del Paine National Park. But what exactly is the W trek? Where is it? Why should you explore it? What is there to see? Let's answer all these questions and more as we explore just what this trek is, and your options for experiencing it.

Base of the Towers

Where is the W Trek?

First off, let's establish the location. We're way down south in the Arctic regions of Chilean Patagonia, in the world-famous Torres del Paine National Park. Famed for its stunning vertical mountain peaks, crisp blue ice sheets, pristine lakes, and elusive yet awe-inspiring wildlife. Hiking the W trek is one of the top bucket list adventures in the world.

What is the W Trek?

Typically, hikers follow the east-to-west route when undertaking the W Trek, the first day you will start at Refugio Las Torres and conclude at Refugio Paine Grande where you will take a catamaran across Lake Pehoé to the Pudeto ferry port and then be transferred back to Puerto Natales. The route traverses three valleys, which together form the distinctive W shape that characterizes the trek. Within each of these valleys lies one of the park's most famous landmarks.

Phenomenal trekking opportunities ring the park's massif, creating the seven- to ten-day Torres del Paine' O' Circuit. However, the shorter and more manageable portion of this ring is known as the W trek – so-called as your route through the park will resemble a W-shape, as you can see in the map below.

Why Explore the W Trek?

Now that we've hammered out the what and where, let's dive into the most important question; why you should explore the W trek! Trust us, this hike packs the very best that Torres Del Paine has to offer into one adventure-filled day after another.

The primary sights will include the three iconic granite towers (torres), for which the park is named. The day-hike up to the main viewpoint is steep but well worth the sweeping views of steep mountain valleys and snowcapped mountains.

Your adventure will also take you deep into the park's inner realm via Frances Valley, where you'll see the magical indomitability of the massif's sheer granite walls, near-endless mountain top ice sheets, and raging rivers.

Continue following your distinctive 'W' path, and you'll find yourself overlooking the gargantuan Southern Patagonian Ice Field – which covers over 4,500 square miles! The sheer vertical ice wall that forms the northern end of Lake Grey (Lago Grey) is truly a sight to behold.

What is the best time of year to hike Torres del Paine?

The best time of year to hike Torres del Paine along the W circuit or O circuit,  is during the summer months of December through February (this is peak season in the park). This is when the weather is the warmest and the days are the longest, making it easier to complete longer hikes. However, the high season can also mean more crowds and higher prices. Spring (September to November) and Fall (March to May) offer cooler temperatures, fewer crowds, and the chance to see the changing colors of the park's foliage. However, hikers should be prepared for potentially unpredictable weather conditions during these shoulder seasons. Winter (June to August) is the least popular time to hike due to cold temperatures, snow, and shorter daylight hours.

What is the difference between the O trek and W trek in Torres Del Paine?

The O trek and W trek are two of the most popular multi-day hiking routes in Torres del Paine National Park, Chile. While both routes offer breathtaking views of the park's glaciers, mountains, and lakes, there are some key differences between the two.

The W trek is shorter and less physically demanding than the O trek, making it a great option for hikers with limited time or experience. The W trek takes around four to five days to complete and covers approximately 50 miles (80 km). The route is named after the W-shaped path it follows, which passes through the park's most famous landmarks, including the Grey Glacier, the French Valley, and the base of the Torres del Paine granite towers.

The O trek, on the other hand, is a more challenging and longer hike that takes around eight to ten days to complete. The trek is named after the circular path it follows around the entire Paine Massif, offering stunning views of the park's glaciers, mountains, and forests. The O trek covers approximately 70 miles (110 km) and includes more rugged terrain, steep climbs, and river crossings than the W trek.

Both the W trek and O trek offer unique and unforgettable hiking experiences in Torres del Paine. Hikers should choose the route that best suits their physical abilities, time constraints, and personal preferences.

Self- Guided vs Guided?

Whether to do a self-guided or guided trek in Torres del Paine National Park ultimately depends on personal preferences, experience, and comfort level with navigation.

A self-guided trek can offer more flexibility and independence in terms of pace and route, as hikers can plan their itinerary according to their preferences and interests. It can also be more cost-effective, as there is no need to pay for a guide's services. However, hikers must be experienced and confident in basic navigation, wilderness survival skills, and have the appropriate gear and equipment. In general the trails are very well marked and easy to follow, for this reason a guide is not needed even for first time hikers.

A guided trek can provide additional safety, support, and knowledge of the area from a local guide. The guide can help with navigation, offer insight into the flora and fauna, and ensure that hikers are properly equipped and prepared for the trek. However, guided treks can be more expensive and less flexible than self-guided options, and hikers must be willing to follow a set itinerary and pace of the greater group.

Where does the hike start and end?

You will fly into either Punta Arenas or Puerto Natales typically via Santiago,Chile or another location in Chile. All of the hikes depart from Puerto Natales via bus or private transfer. There are more consistent flight into Punta Arenas, however if you can book one into Puerto Natales that is typically more ideal saving you the 3 hour drive to Natales from Punta Arenas.

The starting and ending points of the hike in Torres del Paine National Park depend on the specific route or circuit that hikers choose to take. However, the most popular trekking routes in the park are the "W" Trek and the "O" Circuit.

The "W" Trek is a 4-5 day trek that starts and ends at Refugio Las Torres, located in the eastern part of the park. The trek takes hikers through the highlights of the park, including the base of the famous Torres del Paine, the French Valley, and Grey Glacier.

The "O" Circuit is a more challenging 7-9 day trek that covers a longer distance and includes additional areas of the park, such as the John Garner Pass and the backside of Grey Glacier where you will see the amazing hanging bridges. The trek starts and ends at the same location as the "W" Trek, Refugio Las Torres.

Both treks can be accessed by bus or private transfer from the nearby town of Puerto Natales, which is approximately 1.5-2 hours away by road.

Do you want to forget about the planning, permits, accommodations, meals, transportation.... We offer full package trips in camping, or the mountain refugios self guided or guided. Check out our full list of hiking packages here.

Refugios or Camping?

Refugios (refuges) are established rustic style lodge accommodations within Torres del Paine National Park, usually made up of shared bunk beds or private rooms, with shared amenities like kitchens, bathrooms, dining areas, and some spotty wifi that you have to pay for. They are generally more comfortable and convenient than camping, as you don't need to bring or rent your own tent, sleeping bag, or cooking equipment. All of the meals are served in the dining areas of the Refugios and bedding is also included.

On the other hand, camping along the W Trail in Torres del Paine involves pitching your own tent and carrying all your own gear, food, and water (or book our camping program where all the gear and meals are included and camp is setup each night allowing you not to have to carry and camping supplies or food). While it requires more preparation and effort, camping can offer a more immersive and authentic outdoor experience. It also allows you to be closer to nature and enjoy the stunning scenery of the park without any walls between you and the wilderness.

In terms of cost, Refugios are generally more expensive than camping. Additionally, Refugios and camping options require advance reservations, and typically the trails accommodations can book out well in advance 6+ months out.

Whether choosing the camping or refugio option, you can utilize all of the common areas of the refugios, including the dining and cooking areas, bathrooms, and buy snacks, beer or wine, and use outlets to charge your devices and stay warm after a long day of hiking.

Book a Self Guided Package: We recommend booking one of the self guided packages that include everything you need for the 5 Day W trek or the 8 Day O circuit. These packages allow you to arrive in Puerto Natales and all logistical aspects of your trip are made, accommodations booked weather camping or refugees, all meals, transportation via bus to/from the park, your catamaran tickets, park permits, entrance fees....etc -  if camping all gear is setup and included on each night of your trip. You don’t really save any money by booking it all on your own and it can be a real pain.

Want more comfort or a private room each night? We suggest booking our EcoCamp program or the Hotel Program at Hotel Las Torres. Both of these utilize private accommodations and guided day treks and activities into the iconic parts of the park. Please note that the refugio or camping option can be done guided or self guided, but these accommodations are the only way to hike the W or O trek in a thru hike way from lodge to lodge or campsite to campsite.

The EcoCamp - W Trek Experience

W Trek: East to west vs West to East

The W Trek in Torres del Paine National Park, Chile, is one of the most popular treks in Patagonia. It can be done in either direction: east to west or west to east. Each direction offers different experiences and has its own set of advantages and disadvantages. Here's a detailed comparison to help you decide which direction might be better for your trek:

East to West


  1. Iconic Finale: Finishing at the Grey Glacier can be a grand finale to your trek, leaving you with the stunning views of the glacier as your last memory.
  2. Gradual Build-Up: The trek starts with the iconic Torres del Paine (the Towers), giving you an early highlight and then continues through scenic valleys and lakes. Your legs will be fresh for the biggest climb of the 5 days.
  3. Crowd Management: Many guided tours and independent trekkers prefer the west to east direction, so going east to west might offer a slightly less crowded experience.


  1. Potential Wind Challenge: Patagonia is known for its strong winds, which often blow west to east. Hiking against the wind can be challenging and exhausting.
  2. Early Major Ascent: The trek to the base of the towers involves a significant ascent early in the trek.

West to East


  1. Wind Advantage: The predominant winds are usually at your back, making the hike physically easier and more enjoyable.
  2. Easier Start: Starting from Paine Grande to Grey Glacier is a relatively moderate start, allowing you to ease into the trek before tackling more challenging sections.
  3. Scenic Progression: The scenery becomes progressively more dramatic as you approach the Towers, making for a climactic end.


  1. Crowded Finale: The approach to the base of the towers can be crowded, especially on the final day, as many trekkers converge here.

Key Considerations

  1. Weather: Check the weather forecast and wind direction during your planned trek dates. Strong winds are a significant factor in Patagonia.
  2. Fitness Level: Consider your physical condition. If you prefer to start gently and build up to more strenuous sections, west to east might be better.
  3. Accommodation and Campsites: Ensure that you book your campsites or refugios well in advance (book here), as spots fill up quickly. Availability might influence your direction choice.
  4. Personal Preferences: Think about whether you prefer a gradual build-up to a dramatic finish (west to east) or starting with a major highlight and ending with a spectacular glacier (east to west).

Both directions offer stunning landscapes and unforgettable experiences, so your decision should be based on what kind of trekking experience you prefer and the logistical aspects of your trip. Opinion - Both are great options, in the end it doesnt really matter what direction you go.

Hiking the W Trail Alone

Should I solo hike the W trail? Embarking on a solo journey along the W Trail can be a thrilling and rewarding experience for many hikers. The trails are well used so it is easy to make new friends along the trails and in the camping and lodges along the trails. You can also book a group trek in one of our fixed guided departures if you prefer to hike with a group.

Recommendations for hiking alone:

Firstly, it is crucial to register with the park authorities before you commence your hike. This allows the rangers to keep track of your whereabouts and ensure your safety.

Secondly, be sure to pack appropriately for the conditions you will face along the trail. This includes adequate clothing, equipment, and provisions. It's also advisable to bring a reliable map, compass, and/or GPS device to help navigate the trail and SOS anyone in the case you are not near anyone on the trail and you need help.

Thirdly, make sure you are familiar with the trail's route, terrain, and potential hazards. Stay alert for changes in weather conditions, which can be unpredictable and potentially hazardous in this region.

Lastly, it's recommended that you inform someone of your plans and expected return date, so that they can alert the authorities if you fail to return on schedule.

By following these precautions, you can have a safe and enjoyable solo adventure on the W Trail.
