From the hamlet of Charaillin in the commune of Chavornay, an ascent to Chanduraz at an altitude of 1218 metres on the Grand Colombier massif: at the belvedere, a very open view on the Valromey side; a connection is possible with Béon.
After a long climb, you will go back and forth on the rock of Chanduraz and will be rewarded with a breathtaking view of the Alps, the Rhône river winding in the south of Bugey. (The end of the cliff is inaccessible)
