Technical specifications
Road route at 95%. Two mule tracks: the round trip to the Col des Justices (approx. 4 km) can be tricky with 23/25 mm tyres, and the Golet aux Sourdes can be reached by carrying your bike for 400 m (round trip). Otherwise, the route is not particularly difficult, apart from a few steep sections on the climb up to Trou du Sac.
Important observations: in March 2025, the Cerdon road (N 1084) used for descending was closed to all motor traffic due to cliff reinforcement works following recurrent rockfalls between the villages of Labalme and Cerdon.
The beautiful descent along the road known as «Vieux Cerdon» is unfortunately regularly subject to traffic restrictions (D11).
