- The Great and Small Goulets
This corbelled road, accessible since 1854, runs along the Vernaison valley, between Sainte Eulalie en Royans and Les Baraques en Vercors. Laces, aerial sections in cornice, tunnels alternate this route where belvederes allow to admire the cliffs, the Vernaison below and to smell the magical nature in this place.
Arrived at Les Baraques, after having crossed the tunnel built in 2008, to secure this historic road which has become dangerous (the great gullies are no longer accessible) your journey can continue towards Vassieux, La Chapelle-en-Vercors and the Rousset pass, towards the south or up towards Saint-Martin en Vercors, les 4 Montagnes...
- The Col du Rousset and its tunnel: open door, between the Vercors and Provence!
The first tunnel built in 1866 (replaced by a new one in 1979) connects Pont-en-Royans directly to Die, without going through the banks of the Isère. Orientation tables provide a magnificent panoramic view from where you can also observe the majestic flight of vultures reintroduced into the Vercors in 1996.
Die - Bridge in Royans: the RD76 for 60 km
Opened in 1872, it is a road under surveillance and under regular work to secure its route. Even if it has lost some of its plume, this road remains unavoidable, especially in winter, when it is overhung by ice stalactites, causing a "freezing" feeling.... Its construction was a strategic priority to trade with the Pont-en-Royans region and the southern plain of Grésivaudan, then tourism.

- The Gorges du Nan: impressive sensations....
Since 1894, this route has been narrow, dizzying and sensational. Its route, created with rudimentary techniques, has retained its authenticity and provides access to the village of Malleval, a protected site since 1945. Adrenaline lovers will be delighted!

- Combe Laval - Le col de la Machine
Its creation in 1898 was strongly driven by the charcoal makers who exploited the immense forest of Lente. Also built by hand, this road, which hangs on the cliff and overlooks "La Combe", is one of the most popular with tourists. The views extend over the Isère valley and as far as St-Jean-en Royans.

- Ecouges; a strategic necessity!
Based in Saint-Gervais, 800m below the Ecouges forest, the Royal Foundry of Louix XIV's naval guns created an access road to quickly supply the charcoal needed to operate the blast furnaces. But it was in 1883 that a real road was built, between meadows and orchards, and then snaked between the limestone walls and waterfalls, without forgetting the crossing of the narrow and dark tunnel... an entrance into the bowels of the Vercors.
