This is one of the more secluded beaches of Santorini. In Koloumbos, the rocks towering around the beach provide natural shade from the sun and the waters are warm, since the most active underwater crater on the island is located here.Arriving at Koloumbos, you leave your car on the road and follow a narrow trail down the rockssurrounding the beach,but you will be fully compensated for this small inconvenience.
