A beautiful swimming spot where you can go by paddle boat. Afterwards you can take a break on the rocks and even jump in.

Arriving in front of this cave, two things strike you, the dimensions of this gaping mouth as well as the freshness which emerges from it. Truly impressive but not reassuring.

The visit to the cave is worth the detour, it is possible to go quite far inside. The ground is wet and sticky (like wet clay), there are beautiful cavities to observe. Provide a good flashlight because quickly you can no longer see the entrance or the light of day.

Bats live here, it is best not to go too deep into the cave so as not to disturb them

A great swimming spot with rocks in the water. In the rock face by the water there is an entrance to a cave into which you can go several meters. Has scary factor. ☺️
