This article is the second in a series of five detailing each day of the W-Circuit trek in Torres del Paine National Park. The trek was completed starting with the Glacier Grey leg and going west-to-east, though it can be completed in the opposite direction as well.
The second day of the W-Circuit is a fairly short one, you'll backtrack along Lago Grey to Paine Grande and stay there for the night. You may encounter very high winds in the pass between Lago Grey and Lago Pehoé as there is a bit of a wind tunnel effect.
The Paine Grande refugio and campground can be seen below.
There is a trail nearby Paine Grande overlooking Lago Pehoé. You'll probably have some time to kill in the afternoon so this is a good option.
