Papanikolis Cave: One of the world's most renowned underwater caves, located in Lefkada -more specifically in the neighbouring Meganisi-, owes its name to Papanikolis submarine, which used the cave as a base of operations during World War II, and can be reached only by sea. With a total surface area of 3,800 sq.m., it has a length of 120 m., width of 60 m. and depth of 30 m., a lovely natural decor with impressive stalactites and a small beach inside. In case of bad weather, it provides "shelter" to yachts and boats.
Alabaster Cave: It is located in the southwestern part of the island, in the area of Agia Aikaterini, just 1.5 km. from the town of Lefkada. Its discovery dates back to 1970, which was accomplished through a gallery that was opened in a nearby quarry. The impressive stalagmites in its chambers, resembling alabaster decorations, gave their name to the cave, which occupies an area of 1,700 sq.m. The chambers are also named after the formations of stalagmites, such as Snail, Chamber of the Giants, etc. Note that some stalagmites are up to 5 m. long.
