Fantastic panoramic view, no matter which direction you look.

Large cave that is very easy to access, even if it is very slippery because it is wet. Even in summer, you can see your own breath after just a few meters inside. Unfortunately, I didn't know what the big pool in the cave was all about. There is a dilapidated house above, but that doesn't provide any clues either. A real highlight of the tour.
