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

To be done in dry weather, route that can be dangerous in wet weather. A good part of the route is on the T3 side: difficult. A good pair of hiking boots and good experience are necessary

The hiking trail along the stream is not in very good condition. Falling rocks and trees obstruct the path. Progress is sometimes tricky. I recommend reaching the large waterfall via the northernmost path, and then turning around.
