Laguna Torre (Cerro Torre)

One of the most frequented day hikes from El Chaltén, the route to Laguna Torre leads to a glacial lake at the base of the Torre massif. The 18 km out-and-back trail follows the Fitz Roy River valley, moving through sub-antarctic forests of ñire and lenga. The terrain is primarily well-maintained gravel paths and packed dirt, with a short initial ascent followed by mostly level walking through the glacial valley. The destination offers direct views of Cerro Torre (3,128m) and the Adela range, with icebergs frequently calving from the Torre Glacier into the lake.

The Wonderland Trail is exactly what its name implies: a grueling, spectacular, 93-mile (150km) circumnavigation of Mount Rainier, the most glaciated peak in the contiguous United States. This premier backpacking route is notoriously difficult, rarely offering a flat section of trail. Hikers are either painfully ascending a massive, forested ridge or steeply descending into a deep, glacier-carved river valley, only to repeat the process the very next day. The trail passes through towering old-growth rainforests, crosses roaring and milky glacial rivers via demanding suspension bridges or log jams, and traverses stunning, high-alpine wildflower meadows like Summerland and Panhandle Gap where the mountain's massive ice fields feel close enough to touch.
