It's really cool for doing jumps! Be careful not to go too fast especially if it's the first descent here

From the Croix du Bois park, you just have to enter the forest to have fun. The paths and trails are technical, bumpy and sometimes steep. The perfect mix for a great mountain bike ride.

Great spot for mountain bikers looking for thrills! Tested with a gravel bike, I would have preferred to have had a mountain bike, but with caution I was still able to have fun!
