Kato Merdipos is a cave in the village of Erimos in the Lakoniki Mani. Before the first houses of the village follow a short dirt road for 50 m to the SE. Behind the oaks, locally called "phrygana" the Merdipos abyss drops some 70 m deep. Access is only possible via ropes, as the walls on all sides are overhanging and lose rocks.
