Spilia Sykias The Cave of the Fig Tree in SW side of the island is unique because it hides inside a lovely beach. Also known as the Emerald Cave is an amazing part of the cave whose roof has collapsed resulting in the sunbeams that penetrate to create a unique spectacle consisting of thousands of colors. Visited only by boat.
Like almost all beaches in the west side of Milos, Agathia is very difficult to access by land because of a bad road, but is totally worth it especially if you are unable to visit the beach by boat. Its turquoise waters and the wide sandy beach are waiting to reward you for your effort.
