A double waterfall, a 5-minute walk from the parking lot. It doesn't flow year-round, only after the rains, but it's worth the detour nonetheless. Let your imagination recreate it, or come back and see us in the spring!

In summer the waterfall always dries up. A small pond is left. From the top you have a great view.

The Estinettes cave is the resurgence of an underground river. It is therefore impassable in the event of heavy rain.
