The iconic cave located just outside Sami on the road to Agia Efimia
The cave is split into with two chambers separated with an island in the center.
The roof of one of the halls caved in centuries ago letting sunlight filter in.
The depth of the lake is 20 to 30 meters.
When the sun is right overhead at noon, the sunlight hitting the turquoise-blue waters create a magical illusion and the whole cave of Melissani suddenly feels lit with blue light.
