Countless caves are hidden around the island, which was a veritable pirates’ lair for centuries. The pirates spent the winters on the island enjoying the bounty of their catches from around the high seas. The most well-known is the cave of Vromolimni which can be accessed by donkey, by foot or by boat from the main port. The cave of Gerakia is also worth visiting with its pumice. Other caves are carved out of the rock in the same area, some of which are reputed to still be unexplored.
