The famous Blue Cave (Galazia Spilia) is also known as Parasta Cave and as Fokiaki from the seals that live there. It is a sea cave of astonishing beauty at the south side of Kastelorizo that will take your breath away with its incredible blue water and the countless white stalactites which are decorating the vast roof. It is 30 meters tall but its entrance is so low that you will have to keep your head down while the boat is passing inside.
