Sykia is not quite a beach - it is a sea cave the roof of which has collapsed. As a result, a cave with an almost round shape has formed, and a "hole" in the roof from which the sky is seen. Inside there is a small corner of pebbles and stones resembling a miniature beach strip. The cave is accessible only by boat and is usually part of the excursions to Kleftiko
as both are very close.
The big excursion boats and yacht cannot pass through the cave opening, so they bring smaller inflatable boats to transfer tourists inside. The water within the cave has a transparent green-blue color but it is deep and cold.
