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.

It is remarkably rare for a major European capital to have a pristine expanse of ancient primeval forest just 20 kilometers from the city center. Tyresta National Park is Stockholm's wilderness backyard. The premier hike is the purple-blazed Tyrestarundan (The Tyresta Circuit), a 14km (8.7-mile) loop that functions as a highlight reel of Swedish nature. The trail takes hikers through dark, moss-draped ancient pine forests (with trees over 400 years old), past three distinct glass-like lakes, and directly through the stark, silver skeletons of the 1999 forest fire zone. It is immaculately maintained, featuring fire pits with supplied wood, making it the significant accessible day hike.
