Although relatively short, this route is technical and physically demanding, with some dangerous passages at the start, and some sections where you will have to carry your bike at the bottom of the Lestarrezou valley, in the south-eastern part of the route.
The Pédestarrès peat bog is an exceptional ecosystem with a unique flora and fauna. A fun nature trail allows you to discover this mysterious and surprising world, classified as a sensitive natural area. Accessible from the D35 (off the track).
