The slope is quite steep and with a lot of rocks, but it can be climbed without putting your foot down. It's not particularly fun to descend. Better to take the surrounding enduro trails.

The small path is a dead end, unless you are on gravel. When you turn around, enjoy the magnificent view of the Vercors

Please note: dogs are not allowed in the castle gardens, even on a leash. This means you'll have to find a different route around the castle with a dog!
