Moulin de Vulvoz Waterfall

Highlight • Waterfall

It is not a simple waterfall.
Its interest, compared to the many waterfalls in the region, lies in the hole that has been dug in the rock over time.
So you can see the flowing waters of the Vulva flowing into the void, passing through this hole.

(Note: Shouldn't it be called 'Cascade de Vulvoz'?) This waterfall is beautiful! Also in October. We did not encounter any other hikers during the entire route, even at the waterfall we were completely alone. We started 'upstairs', also recommended. There are still walls with some windows still standing. And you see a bowl hollowed out by the water. Then we walked down - a slippery, steep path indeed. We thought it was worth it.

A wonderful walk, an easy, easily walkable route there and back, in September at 30 degrees. The forest, covered in lichen and moss, transports you to the land of the elves. The waterfalls directly from the high rock walls are impressive even in dry periods.

The waterfall is worth it and is a great reward! At the end of a descent into the enchanted forest, these monuments make the ground vibrate as much as the soul. The rest of the hike is memorable because of the positive elevation gain that challenges the calves and thighs. Thank you nature!
