The Gaisalmsteig — Achensee’s Fjordside Path

The Gaisalmsteig is one of the most scenic lakeside trails in the Alps, often described as 'Tyrolean Fjord walking'. Connecting the villages of Pertisau and Achenkirch along the western shore of Lake Achen (Achensee), the trail is only accessible by foot or by the Achensee boat service. The path alternates between wide forest tracks and narrow, rocky ledges that drop directly into the turquoise water. Halfway through, the Gaisalm mountain inn provides a secluded retreat with no road access, reachable only by those who hike or take the ferry.

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.
