Le Bout du Monde (Sixt-Fer-à-Cheval)

Translated literally as 'The End of the World', this spectacular 8km loop is located in the immense limestone amphitheater of the Cirque du Sixt-Fer-à-Cheval. Surrounded by towering 2,000-meter cliffs, this is a predominantly flat, welcoming walk that traces the Giffre river to its source. It is perfect for those seeking high-alpine drama without the grueling climbs usually required to find it. Note: Compiled from public sources — not a field report.

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.
