Description

A rolling and very varied route with alternating single track and undergrowth paths. It crosses the Vassieux plateau from east to west, passing through the Trompe forest, the Serre Charbonnière woods and the Libouse valley.

The first part leads to the Museum of Prehistory, which houses a flint knapping workshop found intact, as it was 5000 years ago! The route alternates between single tracks, paths, and a few short sections of road, crossing the Vassieux plateau from west to east. A steep, but short, climb on a track takes you to the "Raphaël Poirée" biathlon stadium. You then dive into the Trompe forest via a pleasant track, dotted with small steep slopes and beautiful clearings, up to the Pas du Souillet. At Fouletier, the track descends to the causse; along the way, you will notice the ruins of the windmills and the small Saint Mamert chapel.
