From the known caves, those with easy access to the public are Melissani, Karavomilos, and Zervatis.  Other caves are Chiridoni – Sotira and Agia Eleousa, with more difficult access that requires descent with ropes. The salty water is crystal clear with a constant temperature of 14 0C and in summer can reach up to 15 oC.

MELISSANI: Maximum depth of 30m expands to 540m, easily accessible through a drilled tunnel that drives visitors right in front of the lake. A dive (in the lacustrine part) is suitable for all divers with relevant experience. Diving in Melissani is a unique experience; the diffusion of light reflected the walls, and the crystal water gives a dreamy feeling. The illusion of flying into the colors is an image. This is a lifelong memorable diving experience.

The first is the lake’s median that leads to the entrance of the cave accessible to all divers.

The combination of biodiversity towering stalagmites and stalactites curtain gives the picture of a sea cave with land cave features.

Wreck Diving


The British submarine located in southern Kefalonia, sunk by a mine on Dec. 6, 1941. A challenging dive that offers the diver a unique diving experience facing one of the most impressive war machines of the Second World War.

The story of HMS PERSEUS is genuinely unique and has been studied by many historians and researchers. The submarine lies at a depth of 51 meters while maintaining an absolute shipbuilding shape, revealing a huge metal giant that offers protection to underwater life. Big amberjacks and dentexes fish appear unsuspected around the wreck that extends for about 80 m above the sandy sea bed. Genin by the conditions of its immersion and the presence of a single survivor (J.CAPES), who was not a member of the crew, make the legend of the sunken submarine even more mysterious. This wreck dive is ranked among the top 10 dives around the world.

Cristine Lome Wreck

This is a contemporary wreck of a small Ferry Boat of 40m that sank in 2011 near Agia Kyriaky bay. This is an easy dive at 20m depth, where divers may see the whole boat at the sea bed.
