From Saint-Michel-les-Portes, it's about 7 km at an average gradient of 8%. The last few kilometers often reach double digits. A cruel climb if it's the last one of your day...

The Brion Bridge is a suspension bridge over the Hebron River, connecting the towns of Roissard and Lavars. The bridge has only one lane.

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.

It is from the road to La Corniche that we have the most beautiful views of Lake Monteynard
