One of the special highlights in this area. An almost balanced granite rock that you can rock at a certain point - provided you have enough strength. Unfortunately, there are often larger hiking groups with informative guides here...

Essential flashlight and clothing against humidity highly recommended! The cave is considered the longest natural cave in Finistère (180m).
