Trail de descente uniquement, pas tres large et plutot naturel, attention pente forte et dever. Ca commence par des grands virages rapides a flan, pour arriver sur un step down a l'aveugle (mais roulable). Suivit d'un plat avec une toute petite relance mais assez raide, le trail continu sur la crete pour plonger dans le raide apres la traversé d'un chemin pieton. Des passages assez raide et en devers suivent pour finir sur des virages avec pas mal de flow.
Downhill trail only, not very wide and rather natural, beware of steep slopes and worms. It starts with big, fast flanking bends, to arrive on a blind (but rideable) step down. Followed by a flat section with a small but fairly steep restart, the trail continues on the ridge to plunge into the steep after crossing a footpath. Steep, banked sections follow, ending on a series of bends with plenty of flow.
