Blue Cave is the most celebrated attraction of the Greek island of Kastellorizo.[citation needed] The cave lies on the SE coast of the island, and is named by the inhabitants phokialí (Greek for seal's refuge).[1] Being 40–50 m long, 25–30 m wide, and 20–25 m high, it is much larger than the world famous Grotta Azzurra on Capri, Italy.[1] The light of the sun, refracted through the sea, is reflected in the interior of the Grotto, thereby producing a dazzling blue colour. The Cave can be visited only by boat and, since the entrance is barely one metre high above sea level, only under calm sea conditions: the best time of the day to visit is early in the morning, when the sun is still low.[1]
