Tour des lapiaz de Zanfleuron

High-altitude hike from the Col du Sanetsch (2,252 m) across an other-worldly landscape of sculpted rock formations below the Tsanfleuron Glacier. Refreshment stop at the Cabane de Prarochet.

The "Tsanfleuron Lapis" is an impressive rocky area sculpted by the forces of nature, which lies below the Tsanfleuron glacier. On the upper part, until recently covered with ice, the rock is smooth and rounded, polished by the glacier. Below, the rocks released from the ice thousands of years ago provide an eroded and cracked karst landscape over time and with the flow of water. Between the two areas are the moraines that the Tsanfleuron glacier left until 1850. Today, the glacier is about 2 km from this incomparable place in Europe. The hike makes a wide loop around this lunar landscape. The path begins in the hamlet of Tsanfleuron in the direction of the glacier, until the hut of Prarochet (2'556 m), built by the ski club of Savièse. From mid-June to mid-September, this hut is the ideal place to stop and have a refreshment. From there, you can enjoy the view of the Diablerets ski lifts, the impressive "Quille du Diable" rock formation and several 4,000 meters peaks from Valais. The path then leads along the northern side of Tsanfleuron's lapis to the Sanetsch Pass.   Highlights: Spectacular drive up (by car or postal bus) from the Rhône valley Les Lapis de Tsanfleuron – karst landscape of sculpted limestone Cabane de Prarochet – welcoming mountain refuge near the foot of the glacier

Turn-by-turn directions


From the hamlet of Tsanfleuron, follow the yellow hiking trail signs pointing to the Cabane de Prarochet. The second part of the path is then indicated by cairns or painted on the stones. From the Prarochet hut, it is easy to lose the way, so be careful of the markings on the stones to continue northeast towards the Sanetsch Pass.

  • Inform others of the route you plan to take. Whenever possible, avoid going alone.
  • Do not venture onto glaciers without a mountain guide.
