Hiking in Chile
The Sendero de Chile trail runs 18 km from the Serrano Conaf lodge up along the western side of Lake Pehoé, via Las Carretas campsite and Mirador Pehoe lookout, ending at the Pehoe Conaf lodge, and offers views of the Cordillera del Paine, Grey Glacier and Lake Pehoé. 
There are several other well-known hiking trails within Torres del Paine National Park, including the “W”, which leads in and out of the valleys on the south side of the Paine massif, and the “Full Circuit”, which continues on around the less-visited north side of the massif.
