With a length of 120 meters, the Cave of Papanikolis is one of the largest sea caves in the world.
Tourists can reach the cave from the sea via a boat from the Nidri village. It is 12 nautical miles from the town of Lefkada, the water is crystal clear, and everything at the bottom of the sea is visible. What travelers find particularly interesting is the stunning well-preserved beach that they find inside the cave. Location : Meganisi 310 83, Greece
