In winter, the Gastlosen are the stage for a surprising spectacle.
The Grossmutterloch, literally grandmother's hole, lets sunlight pass through a crack in the rock, resembling a fireball. According to legend, this cavity that runs through the Gastlosen is the work of the devil. Angry with his grandmother, he propels her through the mountainside. With Véronique Borcard-Pury, a mountain guide, you will set off on the trail of the solar star. As with any natural phenomenon, numerous factors come into play. Luck will therefore need to be on your side, and nothing is guaranteed, except for a magnificent hike!
A picnic made up of products labelled Parc can be ordered.
The ride on the chairlift is not included in the price.
