The "Black Hole" of Mani, 50 meters long and 30 meters wide, is located near the village of Erimos in Western Mani. It is a mysterious big hole in an area full of stones and low vegetation. A place not seen by the hot sun of Mani and is called Vathia Mouzi according to the minimal information that exists about it.
Thanks to its vertical "walls" and its great depth, the ideal conditions are created for the existence of small forest inside the hole. The forest was created in the cave background, due to the climatic conditions that favor humidity, while the minimal sun that penetrates into the hole contributes to the growth of vegetation.
