Grotta del Pozzo del Diavolo (Monte Venere)

Monte Venere is part of the Monti Cimini group and stands right in front of the waters of Lake Vico.
It is a mountain of volcanic origin that reaches a height of 835 m asl.

The description and pictures on the internet appealed to me, a fantastic hiking car park with a picnic area, a hiking map with a description and signage. Curious, we started the ascent on a well-worn root path, soon you reach the top, still good markings. The path becomes rocky and suddenly a hole. A few meters further down you stood in front of the large entrance to the cave. There is even a rope attached here that you can use to rappel down into the cave, which we didn't do.

Please don't enter into the cavity "Pozzo del Diavolo". It's a shelter for bats and people inside could create noise that disturbes colonies. It is also dangerous to enter: we must report several accidents occourred in this point.
