The access is very well signposted, and you can do a lovely loop hike, starting from Saint-Même-le-Haut, or from Saint-Pierre-d'Entremont for the more adventurous. At the end of winter, the water level can be very high.

It is one of the waterfalls of the Alloix, not the highest, but one of the most beautiful.

Magnificent! But be careful on the second part it is much more technical so hiking is ok, running less so :/

A refreshing and almost magical stopover. I recommend swimming just below the waterfall!

Easy to access, don't take into account the time and mileage, I mishandled it. Allow 30 minutes of walking from the village

At the very bottom of the Saint-Meme cirque, when the walls prevent you from going any further, nature offers a magnificent spectacle. In total, four waterfalls follow one another on the steep cliffs of the cirque, in a grandiose natural setting.
