This themed path allows you, with the aid of consoles, to discover the geology of Salève and its curiosities: The Grotte d'Orjobet, the Trou de la Tine, the arches of La Corraterie, the Grès des Rochers de Faverges and a 360° view of Geneva and Mont Blanc.

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.

1The Orjobet cave

The cave is a large chimney several dozen metres high. It is lit by natural openings and was fully equipped with steps and cables in 1905 by the Swiss Alpine Club.<br/>This cave is located on a difficult hiking trail. Hikers, be warned.

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

On your way back down, you will also pass near the Trou de la Tine, a kind of chasm whose bottom can be reached through a large breach.

In winter, it is not uncommon for the ground to be completely covered with ice, making it quite difficult to cross.
