The Jura Crest Trail (GTJ / GR509)

The Grande Traversée du Jura (GTJ / GR509) is a premier 400km long-distance trail snaking through the gentle, forested mountains along the French-Swiss border. Unlike the high-alpine peaks of the Alps, the Jura is characterized by vast limestone plateaus, dense spruce forests, and rolling sub-alpine meadows. The route is a contemplative journey through a 'Nordic' landscape, offering silence, deep isolation, and breathtaking views over Lake Geneva to the Mont Blanc massif. It is an accessible yet physically demanding thru-hike that showcases a unique mountain culture defined by isolated dairy farms and ancient spruce woods.

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.
