Everything you need to know about the Torres del Paine W Trek

W Trek is the most popular and most celebrated route in Chilean National Park Torres del Paine. Its name comes from the shape the trek draws on the map and it can be completed in 3-5 days. The W Trek is almost 50 miles (80 kilometers) long. It is considered moderately difficult; the total elevation gain is 8,956 feet (2,730 meters), and unlike the O trek, the W trek is open all year. 

However, if you come to Torres del Paine during the winter season, you can only do the W Trek with a guide. You can walk the W Trek in two directions, either from east to west or from west to east. Both options have some pros and cons, but the great thing is that whichever direction you decide to walk, you will not miss any of the breathtaking views.

How many days do I need for the W trek?

We strongly advise allocating 4 or 5 days, with 3–4 nights spent in campsites or refugios in the Torres del Paine, to fully enjoy everything W Trek has to offer. 

If you don't have much time, you can still complete the W Trek in 3 days. In that case, be prepared for a tough walk and a busy schedule. Alternatively, you could skip some of the sights along the W Trek.

The points of interest along the W Trek

The W Trek takes you to some of Chile's most stunning locations. It usually begins or ends (depending on the hike’s direction) in the Ascencio Valley with the Base Torres lookout, then continues through the famous French Valley (Valle Francés), located in the heart of Torres del Paine, where you can truly appreciate the amazing Patagonian nature. And don't forget about Grey Lake and the Grey Glacier, where you can see massive icebergs falling from the glacier's base.

Torres del Paine Ascencio Valley

Ascencio Valley leads to one of the park's most iconic sights, the Base Torres, also known as Mirador las Torres. The valley is characterized by its dramatic landscape and changing scenery, surrounded by steep, craggy mountains. This part of the trek gets tough due to the steep ascents and rocky terrain.

The Base Torres (Mirador las Torres)

The Base Torres is, without a doubt, the goal of most of the visitors and is also what the park is named after. Once you reach the Base Torres viewpoint, you are rewarded with one of the most spectacular views in the park; three distinct peaks of the Towers of Paine rising above a turquoise glacial lake. 

Torre D'Agostini (also known as the South Tower), Torre Central, and Torre Monzino (also known as the North Tower) stand more than 8,200 feet (2,500 metres) tall.

Torres del Paine French Valley

The French Valley (Valle Francés) is one of the highlights of the Torres del Paine. It's situated between the highest peak in the Paine Massif, Cerro Paine Grande, with its hanging French Glacier, and Los Cuernos peaks. The route follows the French River through beech forests to Mirador Francés and Mirador Británico, where you can enjoy spectacular views of the surrounding peaks.

When planning this portion of the hike, keep in mind that the French Valley route (from Camp Italiano to Mirador Británico) is not open 24 hours a day. Typically, it closes in the afternoon. It means you have to start this portion of the trek before that. The closing time varies, so you may need to check when you arrive at the park.

French Glacier

The French Glacier (Glaciar Francés) is one of the most remarkable features of the French Valley, and it can be observed from certain points along the trail. French Glacier, like many glaciers in Patagonia, is active. This means it regularly calves large chunks of ice into the valley below.

Los Cuernos

Los Cuernos, also known as the Horns, is a breathtaking mountain formation known for its horn-shaped granite peaks and multicolored contrast due to the various types of rocks. It can be viewed from several locations along the northeastern shore of Lake Nordenskjöld.

Grey Glacier

A massive glacier is one of the most visited sights in the park. It is part of the Southern Patagonian Ice Field and measures about 30 meters high and 6 kilometers wide. It’s located in the western part of the W Trek and can be best observed from several viewpoints. You'll discover the most popular one near Refugio Grey.

How to walk the W Trek

This is the eternal question. Is it better to hike the W Trek from west to east or from east to west? In our opinion, it makes little difference. The west-to-east direction is more popular. It also allows you to witness the sunrise at Mirador las Torres (if you spend the night in Chileno). However, if you do not need to go there early in the morning to catch the sunrise, base your decision on logistics and personal preferences.

W Trek West to East

This direction follows the counter-clockwise path from the park's west to the east.

Points to consider

Gradual difficulty: Starting the trek on the west side allows for a more gradual increase in difficulty. In the beginning, the terrain is relatively easy, giving you more time to become accustomed to walking each day.

The best for last: If you consider the Base Torres to be the park's highlight, save this experience for your final day.

Transportation: It’s often easier to start the trek in the west because of the catamaran from Pudeto to Paine Grande. 

W Trek East to West

This direction follows the clockwise path going from the park´s east to the west. 

Points to consider

Starting strong: If you begin at the east, you will tackle the most challenging parts of the trek in the first two days and then you can relax more and enjoy relatively easy terrain.

Less crowded: More people choose to head in the opposite direction. This can sometimes mean that you will see fewer hikers in the early morning.

How difficult is the W Trek?

The W Trek is considered moderately difficult, but this can vary. It really depends on your experience, fitness level, and the weather conditions.

Every day, you walk for 6-8 hours and cover a distance of approximately 9-12 miles (14-20 kilometers). In addition, the terrain in the French Valley and the hike to Mirador las Torres are steep and physically demanding for those unfamiliar with multi-day hiking.

Remember that the weather in Patagonia can be unpredictable, and you may experience sun, rain, snow, and winds all on the same day. That means you must be prepared and have the proper equipment.

The good news is that there are many accommodation options along the way where you can at least take a break. Also, the trail is well marked, and the park is frequented by hikers, making it difficult to get lost.

 When is the best time to hike the W Trek?

In general, the best time to visit Torres del Paine National Park is during the summer months, which in Chile are December through February. The weather is milder, the days are longer, and everything is open, including campsites and restaurants. The park is bustling, and there are numerous hikers. However, if you prefer to visit the park during the off-season while still having access to the majority of the facilities, come in April. The rates can be slightly reduced, and it is much easier to find available accommodations.

From November until early December

Patagonia's spring will be your favorite season. The park is a little less crowded, wildflowers are blooming, and nature is awakening. However, the weather can be unpredictable.

Mid-December to February

Definitely the peak season. The weather is warmer; however, the trails and accommodations are usually crowded.

March

It is still considered the peak season, but the crowds begin to thin out as time passes. It's a popular time for those who want to enjoy the park with fewer visitors.

April

As autumn approaches, the park becomes less crowded, and the landscape bursts with autumn colors. However, the weather cools and the days get shorter. We recommend this time of year for more experienced hikers.

What to pack for the W Trek?

Packing for the W Trek requires careful consideration of the changing weather conditions. It also depends on whether you're renting camping gear, staying in refugios, etc. Check out this list of essential items to pack for the W Trek in Torres del Paine National Park.

Backpack: A comfortable and durable backpack (40-70 liters) is ideal for transporting all of your gear. However, if you have reservations for refugios or tents with sleeping bags and have also made meal reservations, a smaller backpack for your clothing will be adequate.

Clothing: Keep in mind that the weather in Patagonia can be unpredictable, so pack at least two sets of clothing. You may get wet during the day, so have a spare set of clothes to keep you dry and warm at night. To protect your clothes, consider using a plastic bag or waterproof case. Here are some suggestions for what you might need.

• Base layers: moisture-wicking underwear and thermal base layers for warmth
• Outer layers: waterproof and windproof jacket and pants
• Trekking pants
• Fleece or down jacket
• T-shirts: both short-sleeved and long-sleeved for layering
• Quick-drying underwear and socks
• Gloves and a warm hat
• Sunglasses

Footwear

• Sturdy, waterproof and broken-in hiking boots with ankle support
• Gaiters to keep dirt and moisture out

Gear (if staying in the camp most of the time)

• Tent
• Sleeping bag (suitable for low temperatures)
• Sleeping pad to provide insulation and comfort. Even during the summer, temperatures in Torres del Paine can drop significantly at night. The ground can be very cold, and a sleeping pad provides a barrier between you and the ground, keeping you warm throughout the night.
• Headlamp and extra batteries
• Trekking poles (only if you are used to trekking with them)
• Multi-tool or knife
• Water purification method (iodine tablets or a filter)

Cooking and eating

• Lightweight stove and cookware

• Water bottle or hydration system

Personal items

• Insect repellent
• Toiletries (toothbrush, toothpaste, biodegradable soap)
• First aid kit
• Dry bags or plastic bags to keep clothing and electronics dry

Miscellaneous

• Cash
• Permits, identification, and confirmations about the reservations

Keep in mind that the key to comfort is layering, as the weather can change rapidly. Remember to pack light, as carrying too much weight can make your trek more challenging.
