Lauterbrunnen to Wengen — The Steep Ascent

This is the classic pedestrian route connecting the 'Valley of 72 Waterfalls' (Lauterbrunnen) with the car-free mountain terrace of Wengen. The trail is a relentless but beautifully engineered series of switchbacks that climb directly up the eastern wall of the valley. As you gain height, the Staubbach Falls—one of the highest free-falling waterfalls in Europe—reveals its full scale. You walk through dense pine forests and past lush meadows where the sound of cowbells and the passing yellow-and-green Wengernalp train are the only distractions.

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.
