The W Trek is a trail of approximately 70 kilometers that passes through some of the most iconic places in the park. Its name is due to the "W" shape that it describes on the map due to its itinerary.
The route begins in the Pudeto sector, from where you can take a catamaran to cross Lake Pehoé to the start of the trail. From there, the trail heads west, bordering the lake and passing through the Valle del Francés.
Then, the route heads south towards the Glacier Grey sector, where visitors can see the impressive Glacier Grey and walk through the sub-Antarctic forest.
The last part of the route is the bottom part of the “W”, which includes the Valle del Ascencio and the view of the Torres del Paine, the three granite towers that are the icon of the park. To get there, visitors must climb a steep hill called Mirador Base Las Torres.
