12 Things To Know Before Hiking the W Trek in Patagonia's Torres del Paine in 2022 & 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. It’s not that physically challenging, but 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 mid-trek detour into the French Valley, which feels like one of the most untouched parts of the Torres del Paine. The French Valley reminds me of a hidden Shangri-La filled with wildflower meadows and chiseled sculpturesque mountains. Adding to the physical beauty of it all, the hiking route is fantastically well-organized with designated campsites 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. 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!
2. What are the best parts of the W Trek? (Trip Highlights)

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 for me were:
- 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.

- Los Cuernos – A set of twisted mountains dominating the northern view for much of the hike.

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. Read More...
