In a fantastic scenery, not far from Villefort in Lozère, the Haut Chassezac is one of France most famous canyons.
No doubt this is the most beautiful in the area and it deserves to be done in its full version.
We can find there everything we expect while canyoning: abseils, slides, jumps from different hights, and special secret passages!
A nice video to have a look at it here.
No need to be an expert, and technical skills will come along, but the course is long therefore it's important to be in a very good physical condition.
