The west side of Paxos is dominated by wild landscapes. Sea caves, hidden into vertical cliffs, were sculpted by the waves, forming amazing geologic wonders. The locals call them “graves”. They were named after the vibrant blue color of the surrounding waters. Some are so big that ships can pass through them. It is said that, in the “Cave of Ypapanti”, the most famous one, the Greek submarine “Papanikolis” was hidden, during the Second World War. You can reach them by boat, following an organized cruise or renting a private vessel. When you get there, do not miss the opportunity to swim through them. It will be an unforgettable experience!
