Les Cerfs Blue Trail at Le Tour, Chamonix, Mountain Biking, VTT Chamonix
The bottom half of Le Tour, the Upper half is called "Variante Chevreurils" that I have a video for as well on my channel. This trail is accessed by the Charamillion gondola - just up the road from Argentiere. Take the train to Argentiere, get off at Montroc - bike last bit to Le Tour base.
