One of the most difficult trails of the Salève by its duration, its elevation and including aerial passages. It is aimed at experienced hikers. Follow in the footsteps of Horace Bénédict De Saussure, a scientist and mountaineer from Geneva who discovered the Grotto, named after his guide: François Orjobet.

The Grotto is lit by natural openings and was entirely fitted out in 1905 by the Genevoise section of the Swiss Alpine Club with steps and cables to be able to cross it easily.

After crossing the cave, you will pass through the Crêts mountain pastures and their panoramic views of the Genevoise plain on one side and the Mont Blanc on the other.

During your descent you will also pass near the Trou de la Tine which is a kind of chasm whose bottom can be reached by a wide gap.

1 La grotte d'Orjobet

The cave is a large chimney which measures tens of metres high. It is lit by natural openings and has been entirely fitted out by the CAS with steps and cables in order to be able to cross it easily.<br/>In the winter it is not rare for the ground to be entirely covered in ice which makes its crossing quite difficult.
