Reception & Facilities

Welcome to the Furon Bas Canyon, the premier canyoning destination in Grenoble since the 1990s! Your CANRIV guide will welcome you and outfit you with a neoprene wetsuit, socks, a helmet, and a harness. After a 15-minute approach hike, the adventure begins.

On the Way to Adventure

It's a 15-minute walk to the entrance of the canyon in the Vercors Massif. It takes a moment to realize that you're just a few minutes from Grenoble and in such a wild setting.

Safety briefing and entry into the canyon

A comprehensive briefing is provided before entering the Furon Bas. The guide explains the obstacles, siphons, and available options. The route is tailored to each person’s skill level, with several possible entry and exit points.

The Canyon Adventure

The Furon Bas starts off strong with large-scale obstacles right from the beginning. The 20-meter rappel down a travertine waterfall is the canyon’s signature section—a moment no one forgets. The descent continues with optional siphons to explore, progressive jumps of up to 12 meters into deep pools, and natural slides. The water, fed by the Sassenage caves, is cold and crystal-clear. A short but intense canyon that surprises at every turn.

The Return of the Heroes

No walk back to Furon Bas—we exit directly at the finish line. A rare luxury in the world of canyoning.

Removal of Equipment and Return of Materials

We return the equipment and find our belongings dry. The water in the Sassenage caves was cold, but the wetsuit did a remarkable job.

A Fun Time & Memories

We’ll make the descent again, with the guide providing commentary. The 20-meter rappel and the siphons are always a hit. CANRIV offers souvenir packages to capture your canyoning adventure in Grenoble: professional photos and videos in the Standard Package, Couples Package, or Premium Package. Ask your guide for pricing on the day of the trip.
