At the most southern point of the island, Vlychada is considered a very special beach because of its volcanic landscape and the rocks that surround it.
The sea has formed many recesses and caves to explore. While there are umbrellas, you will not find it difficult to isolate yourself if you so desire.

In the secluded areas of the beach, once you get past the sun loungers and the picturesque beach bar built like a "natural cave in the rocks" you can get naked.
Extra bonus: at this point it doesn't catch the mobiles. At the end of the beach there is the Theros wave bar, built on a hill above the rocks, adapted to the aesthetics of the environment and with a special view
