Very technical course. At the beginning, a nice short and fast climb, a good warm-up, leading to the Thivoley ponds appreciated for their calm. Recurring wood cutting, prefer weekends.

Panoramic view of the lake rewarding a 2nd ascent on a slope.
Herons and frogs welcome mountain bikers after a very stony descent. Trail sometimes muddy. The end of the circuit zigzags in the plain of Blaune and returns via the old Chartreuse, the Sylve Bénite and the village of Le Pin.

FIELD NEWS (June 2022): recurring woodcutting. For your safety, do not enter the area if construction sites are in progress. Prefer the weekend!

Additional information : Water point and public WC at the start of the circuit.
