The cave’s name is borrowed from the historic submarine “Papanikolis” who used to use the cave as a refuge base during World War II.

​

Thanks to its size, the cave of Papanikolis is the largest sea cave in the world.

The cave's entrance leads to a 120 meters tunnel, which is 60 meters wide to start with, tapering to 23 meters as you advance.

​

Every year attracts visitors to admire the magnificence of its natural beauty. You can reach the cave only from the sea.

The water inside the cave is so crystal clear that you can see the bottom of the sea and beautiful stalactites hanging on the roof. Inside the cave, there is a small beach carefully preserved.

​

Definitely, one of the most amazing sites you can swim in the world.
