To the west of the park and off all of the main trails, this mirador ('look-out point') offers a unique perspective on the national park and you're unlikely to see more than a handful of people on the trail. It's a fairly steep 2 hour climb, from the parking area next to Hotel Grey, up a well marked path to the top. Up top you are pretty free to rome and find a sheltered spot to admire the Paine Massif, the Grey Glacier and most of the lakes of Torres del Paine National Park's lakes, each a different shade of blue.
