The Vallon des Mottes is the work of glaciers and men.
Its slopes rounded by erosion shelter the remains of mining, visible everywhere for those who know how to see.
The routes, between farmland paths, forests and windswept mountain pastures, offer you superb views of the Vercors, the Trièves and the Matheysine.
A stop at the Mine Image museum will allow you to better understand what you will have glimpsed during your trail.
