This technical route, located at the top of the commune of Saint-Martin-de-Queyrières, offers a cool, sporty ride through larch forests.

This mountain bike route takes you to one of the main climbing sites in the Pays des Écrins, known as La Roche Baron. Next, you'll reach two small hamlets in the commune of Saint-Martin-de-Queyrières, both built around their mountain pasture chapels. Both villages lie on the banks of the torrent that shaped the Saint-Sébastien valley. The route ends downhill in a coniferous forest overlooking the village.
