Grand Goulets

From Pont-en-Royans, a little town situated at the junction of the Vernaison with the Bourne, the road crosses the two rivers and continues southeast up the Vernaison valley to enter the picturesque Vernaison gorges. After passing through the Petits Goulets it climbs, with many bends, to the grandiose Grands Goulets, in which the road is caught between high rock walls above the foaming river. After passing through a series of tunnels and galleries it emerges suddenly into the green Vercors valley.
