Gorges du Nan

Highlight (Segment) • Natural Monument

Connecting Cognin-les-Gorges to Malleval-en-Vercors, in the Vercors massif, the Nan Gorges are a canyon through which the Nan River flows.

A cantilevered road clinging to the rock face, it features three tunnels spread over 200 meters and requires no lighting.
