Blue Cave in Kastelorizo (Megisti), Dodecanese, Greece

"This little known underwater cave is one of the largest in the Mediterranean Sea, often visited by sea lions native to these waters. Kastelorizo being one of the smallest Greek islands in the Dodecanese is known more to sailors than to the general traveler but if you do find yourself on this charming island a visit to the "Blue Grotto" is a must. 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."
