Description

Hike through breathtaking landscapes in the heart of the forest of the great Bournillon cirque

This hike invites you to explore some of the most remarkable sights of the Vercors region in the heart of an exceptional natural environment. In just a few kilometers, the route crosses a wide variety of landscapes, alternating between meadows, undergrowth, balcony paths, and viewpoints overlooking the surrounding mountains.

The route leads to the discovery of the spectacular Moulin Marquis waterfall, whose waters plunge nearly 400 meters down the cliff, as well as the mysterious Devil's Gate, a striking rock formation that has long fueled local imagination. Between natural caves, imposing cliffs, and forest settings, each stage holds its own surprises.

This walk also offers a chance to delve into the history of the area. In the 19th century, the inhabitants of Saint-Julien-en-Vercors used these paths to transport their wheat to the Moulin Marquis mill. Today, the forest has largely reclaimed the land and now envelops the vast Bournillon cirque, creating a wild and unspoiled setting.

Delicate passage

Be careful on the steep, rocky ascent and descent near the Devil's Gate. Attempting this route after rain is strongly discouraged, as the terrain can become very slippery. Appropriate hiking boots and extreme caution are essential.
