Sikia is one of the most beautiful and biggest sea caves of Milos. It is located in the southwest part of the island, 13,6 nautical miles from Adamantas. You can approach it with boats that tour around the island. Ask, before you book, if they stop for swimming in Sikia cave. A lot of them, only stop outside the cave without go inside. Characteristic of this cave is that a boat can pass through its entrance. And this is because it has a height of 5m and width of 20m.
A natural skylight was created after the fall of the roof that filled the cave with light. Sunbeams light the cave's interior and make beautiful colorings that charm sensations. It is a once in a lifetime spectacle that only the visitor of Milos can experience!
