The climb is on a forest road, tarmacked for the most part, with the less steep part closer to the white path. It should be possible to reach the Col de Menthières by mountain bike, but it's a dead end by road.

Montée sur Route Forestière, goudronnée dans l'ensemble, la partie la moins raide étant plus proche du chemin blanc. En VTT il doit être possible de rejoindre le Col de Menthières, mais en route c'est un cul de sac.
