Manival singletrack

After going up the left bank forest path, this little single track on the other bank will be more fun for the descent. The strongest can try the climb from this side 🏆

Tour d'Arces and View of the Grésivaudan Valley

Highlight • Castle

First in the snow for this winter.
It's not the best to leave at past 3:30 p.m. for "a little tour" without light... It's a nice descent without visibility, with some nice slips or falls when stones appear unexpectedly under the snow! 🤪
