This is one of three mine shafts in the Mure basin. The shaft at La Motte d'Aveillans was closed in 1956. Today, it is a museum that traces the history of coal mining in La Mûre.

The little road that goes down from Cholonge is great and on arrival you have a superb view of Lake Lafrey

A pass of about fifteen kilometers, with a 1,000 m elevation gain. Almost always in the shade, with little traffic.

Along this path, you alternate between wooded corridors and open balconies. Here, precisely, you can admire the turquoise waters of Lake Petichet. A real call to swim. If you go back down, the lake is not that far.

A quiet road above the main road between Monteynard and La Motte-d'Aveillans, and below La Peyrouse. There are views of Mont Aiguille in the distance as you head towards Monteynard. In the other direction you have towards Le Grand Serre.
