Laguna Torre is a 16.6 mile out and back trail located near El Chaltén, Santa Cruz, Argentina that features a lake. The trail is rated as difficult and primarily used for hiking, walking, and backpacking.
Hikers hoping to get a perfect view of Cerro Torre should set off for Laguna Torre, a glacial lake at the foot of the mountain. The lake is a reasonable turn-around point for a day hike out of El Chaltén, and is reached via an interesting, but not overly taxing, trail. The trailhead on Calle Riquelme is marked with a sign, and, after leaving town, the path closely follows the Río Fitz Roy valley. At the end of the trail, you will have to ascend a small moraine and some sand dunes, but it is the view of Cerro Torre, rather than the climb, that is likely to take your breath away.
Go to Argentina!!!
This is a great hike. I consider it moderate, not hard, unless you have a guide to take you across the river to the glacier.
