Alta Via 1 (Dolomites)

Alta Via 1 is a primary long-distance mountain trail in the Italian Dolomites, extending from Lago di Braies in the north to Belluno in the south. The trek traverses significant limestone massifs including the Fanes-Sennes-Prags Nature Park, the Tofane, Pelmo, and Civetta. Far from the more technical via ferrata-heavy routes in the range, the standard Alta Via 1 (High Route 1) is an established high-altitude hiking path accessible to fit hikers without technical climbing equipment. The route stays predominantly on high-alpine balconies and plateaus, offering a comprehensive transect of the Central Dolomites.

The trek to Laguna de los Tres is one of the primary day activities in Los Glaciares National Park, providing a close-perspective view of the granite massif of Mount Fitz Roy (3,405m). The route follows an out-and-back trail through mixed forest and glaciated valleys, passing the Piedras Blancas viewpoint before the final ascent. The journey is defined by a significant transition from the low-lying valley floor to the high-alpine environment of the lagoon, which sits directly below the main peaks.
