Veyrin is a small village rich in curiosities. You can find an old bread oven, a mural on iron, and metal sculptures there. A beautiful place to stop for a moment.

The pass, located at an altitude of 1,050 meters, offers you a magnificent view of the Alps and the Rhône valley. Like most of the peaks in this region, it sometimes allows you to see Mont Blanc.

Nice single-track trail along the stream. Downhill it's okay but sometimes you have to put your foot down. Uphill...good luck! In the wet season, there are small fords. Nothing extreme but you must already have a small level
