The W Trek in Patagonia – All Your Questions Answered

Patagonia’s famous W trek is an adventure of a lifetime. The five days you’ll spend hiking from the foot of the Torres Del Paine to the Grey Glacier, may become some of the most memorable experiences of your life. However, before you fly halfway around the world, it is very important that you properly prepare for your treck. While I was doing the W Trek, I encountered people who came unprepared because they didn’t do enough research. This unfortunate situation resulted in some being stranded and getting escorted out of the park(story below). Keep reading to learn everything you need to know about Patagonia’s W Trek, updated for 2020 and 2021.

The very first morning of the W trek starts off with a hike to the base of Torres Del Paine. The lake at the foot of the mountains is a spectacular clear glacial mirror and the towers (they call them north, south and central tower) seem almost close enough to touch. On occasion there may be a climber on the tower although I am told they are pretty hard to see. The trek from your first Refugio to the base of the mountain is about 4 hours there and 4 hours back. The trail, as everywhere in the park is very well marked but also very crowded. Many people come from outside the park for just one day to see the lake so this is definitely the busiest portion of the trail. If you are the super adventurous type you can camp out close to the mountains in the Campamento Las Torres (reservations must be made in advance) and get to the lake before sunrise. Just a word of warning – you are very far south so sunrise is usually around 4 am. As for myself I made it there around 1 pm and it was just beautiful 🙂 #backpackerstory

The W Trek – The Complete Experience

Day 1: Torres Del Paine 

The very first morning of the trek starts off with a hike to the base of Torres Del Paine. The lake at the foot of the mountains is a spectacular clear glacial mirror and the towers (they call them north, south and central tower) seem almost close enough to touch. On occasion, there may be a climber on the tower although I am told they are pretty hard to see.

The trek from your first refugio to the base of the mountain is about eight hours roundtrip. The trail is well marked but also very crowded. This trail attracts day hikers so this is the busiest portion of Patagonia’s W trek. If you are the super adventurous type you can camp out close to towers in the Campamento Las Torres (reserve in advance) and watch the sunrise over the lake. However, keep in mind that you are very far south, so in the Chilean summer (December, January, February) sunrise starts as early as 3 am.

Travel Tip:

Torres Del Paine (the trek to the lake with the three mountains) is a trail many people do on a day hike. If you just want to visit the famous towers you can easily score a hotel in the park. You do not need to hire a tour company to visit Torres Del Paine.

Day 2: Lake Nordenskjold

On the second day of the W Patagonia trek, we walked from Refugio Las Torres to Refugio Los Cuernos. On this portion of the trek, you are walking between Lake Nordenskjold (named after the Norwegian explorer who first studied it), and Mount Almirante Nieto. This is an easy day with about 8 hours of trekking over what our guides called “Patagonia Flat” terrain. Be careful not to confuse “Patagonia flat” with “International flat.” Patagonia Flat can mean anything between 0 to 25-degree elevation, but usually, it also means there is no sustained trend up or down.

After a while “Patagonia flat” was the running joke, as we also got to experience a “Patagonia summer” (when it randomly began to snow on a 70-degree day) and Patagonia gravity (when our backpacks grew heavier by the hour, supposedly due to our proximity to the south pole).

W-Trek Travel Tip:

If you really want to go a little fancy with your hiking equipment invest in a higher-end backpack and high-end hiking boots. Go in-person to a specialty store such as REI where they will help you get a proper fit for both.

Day 3: The French Valley

Day 3 of Patagonia’s W trek takes you from Refugio Los Cuernos to Refugio Paine Grande. This is a long day since you are hiking the entire middle leg of the W trek. After making our way from Los Cuernos with our full backpacks, we stopped at Campground Italiano and switched to a daypack. We left our big bags at the campground and made our way up to the French Valley viewpoint. Some of our group decided to turn back about halfway through (it’s a very long way up to French Valley) but those of us who continued were rewarded with viewpoints at 1,100 meters. After making our way back to Camp Italiano we trekked with our full bags to Paine Grande for a happy end to a long and lovely day.

Day 4: The Grey Glacier 

On the fourth day of Patagonia W trek, you walk towards the Grey Lake and Glacier. The glacier is a massive ice structure and extends as far as the eye can see. The Grey Glacier is so-called due to a grey color in its sediment, different from most glaciers (which are blue).

Approaching this area the temperature drops and the winds pick up. On this day we got lucky, with no rain or snow in sight. The winds felt deceptively calm and the sun peaked through the clouds. The weather on the Grey Glacier side of the park is notoriously unpredictable and can be dangerous, as I learned the very next day. We would soon discover how quickly Patagonia’s weather can change and how important it is to be prepared for everything.

Day 5: (Optional) Paso John Gardener

The W trek traditionally ends at the Grey Glacier. Therefore, on day five you have a few options. The first option is to rest up after the trek. The second, to explore the glacier and the lake. The last is to forge ahead to the Paso John Gardener, the highest pass in O Circuit. The advanced O Circuit continues after the end of the W trek and requires about 10 days to complete. You won’t find any refugios after the Grey Glacier, so those adventurous soles who do the O circuit must carry their own supplies.

Our guides told us that those who wanted to climb the pass would have a long day ahead. In the end, only four of us opted for the hike – the rest spend several hours canoeing around the Grey Glacier, it looked like a lovely experience. The Paso John Gardner hike is very difficult, and I don’t recommend it unless you are in fantastic shape.  Make sure you have good equipment too. Although you can get away with Amazon type equipment during the rest of the trek, the pass calls for higher-end, professional supplies. We got caught in a terrible storm on a bare mountain, and my inexpensive windbreaker was not much help.
