The itinerary can be accessed in fine spring weather. However, the passes may still be snow-covered. The busiest period is between 15 July and 15 August. Accommodation will be more difficult during this period. From September-October, the fine late summer days are ideal for discovering the Hauts Plateaux in the beautiful light.

For quicker access to the wide open spaces of the Hauts Plateaux and to enjoy the Nature Reserve, you can set off directly from Corrençon. If you want to enjoy a magnificent view of Grenoble, take the first part of the GTV (Grande traversée du Vercors).

On the first part of the route (Saint-Nizier-du-Moucherotte to Corrençon en Vercors), you can sleep in gîtes and accommodation in the villages (Lans en Vercors, Villard de Lans and Corrençon en Vercors). You can also bivouac on this section. On the second part of the crossing (Corrençon en Vercors to Châtillon en Diois), you will be completely self-sufficient, with the option of staying in the unguarded huts on the plateau. You are also allowed to pitch your tent and bivouac for the night, but please follow the bivouac instructions. Here is the list of unguarded huts: https: //montourenvercors.com/organisez-votre-sejour/cabanes-et-sources/

Are there any water points? 💧

Water is a very rare resource in the Vercors. Before setting off on the traverse, make sure you take enough water with you. Many springs, even those shown on the maps, have actually dried up. List of water sources and their flow rates: https: //www.parc-du-vercors.fr/info-sources

What to do about patous (guard dogs)? 🐕

Patous may be present on your walk. They are there to protect the herds from any outside attack. Make sure you remain calm and adopt the recommended gestures when faced with these animals: signal your arrival, keep a safe distance, accept confrontation, don’t be aggressive and don’t run away.
