The tip about the hiking poles was very helpful, because the last 150 meters to the waterfall are tough for inexperienced hikers. But the view is very beautiful. We were able to watch a group abseiling down the waterfall

The Morgon cirque is a natural cirque whose arc faces north. It forms a beautiful plateau halfway between the valley and the crests of Morgon. Thus, the base of the cirque constitutes a superb preserved natural site, out of the way, where wildlife likes to take refuge.

Near the Serre-Ponçon dam, you can enjoy this picturesque and dizzying road with almost no traffic to overlook the Blanche River. Be careful on the road though, it is not uncommon for small landslides to occur and stones to be found in the middle of it.

A wild and picturesque place and very rich in environmental terms: exceptional plants (orange lilies, goat's beard, coal, yew) colonize its inaccessible walls. The waterfall offers us, through its different lighting, and throughout the seasons, a very beautiful and always renewed spectacle. It is also an archaeological site since in 1953 workers discovered over the waterfall, under a rock, about forty ancient weapons dating from the 4th century BC. They are currently stored in the Digne les Bains museum.
