Very rocky underfoot and quite steep in places, with narrow walkways and steep drop-offs. A beautiful route full of history, not for beginners as quite physically taxing at times and technical in places,

A very beautiful hike above the Gorges de l'Enfer, very narrow. It took us more like 4 hours because we were slower, with photo stops. The hike is indeed intermediate level. However, the magnificent passage of the mast path has no guardrail on the side of the void, and is sometimes narrow. I do not recommend it for people with vertigo, or for young children. Part of the hike, on the flat area after the two refuges, is in the shade of oaks and ash trees, welcome to the climb!

We have visited it a couple of times even with children (quite responsible), highly recommended and risk-free. Very hot in central summer hours
