The region of Asterousia has several small caves with few stalagmites and stalactites. They have great cultural interest as they have been used from prehistoric times until today as residences, shelters, hermit dwellings, or places of worship.
Many of the caves remain unexplored and are not open for visits. Some of the known caves of Asterousia are Kassiani, Sarakinospilios, Peristeria, Varvakospilios, Plakospilios and Ble.
The cave of Miamou and Eileithyia present archaeological interest, while the caves of Goumenospilios and Agios Antonios are inextricably linked with the religious and ascetic history of Asterousia. A path leads to the cave of Agios Antonios with its impressive decoration, 35m high entrance, a small church, and a magnificent view to the sea. Within the gorge of Agiofarago you can see Goumenospilios, one of the oldest hermit sites. The cave has a small entrance and an impressive, vaulted ceiling with an opening. According to tradition, 300 hermits used to live inside the cave and communicated between them only once a year, on the day of the Resurrection of Christ.
