These gorges are particularly fascinating when the water flow is significant. My recommendation is to come and admire this jewel of Ain in spring, when the snow melts.

One of the most beautiful waterfalls in the region. Even if that day she was not too wet....The clear and fresh water of the Arena brings a little freshness!

Located inside the forest, this impressive example of a tufa waterfall is only accessible during heavy rain. Either way, it's worth taking a look.
