One of the many caverns in these hills. In this cave a utensil was found in the shape of a beetle (coléoptère).

The front part of the cave is an open grotto, at the back there is a barred gate that blocks access to the actual cave.

December 10, 2023, Sainte-Anne Cave and Rocks

Via a stone staircase you reach the rocks of Tilff, a fairly well-known massif where you sometimes see climbers in action, and the Sint-An cave just next to it, where cavers have been doing their thing for many years. You can only view the beginning if you are not a caver.
