Presentation
The Grosdar river is located 5 minutes from Saint-Claude in the Jura. It's the most vertical canyon in the Jura massif in its upper section. For the half-day trip, we do the lower part, which is much less technical but much more playful.
It's a canyon that can be explored in a half-day for beginners or families wanting to discover this activity.
The lower part of the Grosdar canyon is a beautiful walk with your feet in the water, featuring numerous small, sometimes technical jumps as well as natural slides in a lush environment.
