Highlight • Mountain Pass

Small pass easily accessible from the Ruchère Nordic Center, via a snowshoe trail. The path is often quite well-packed, so snowshoes should remain on your bag.

If you walk from the Col de la Ruchère down to the Habert de Billon, there's a perfect picknick spot just under the col, at the edge of the woods.

Ruchère Pass

Highlight • Mountain Pass

Also worth the climb if you do not continue to the Petit Som or the Grand Som. The view down the valley of Saint-Bruno, with the Charmant Som at the opposite side is pretty good.
