Melissani lake

I recently visited Melissani lake on the island of kefalonia, it is a unique cave structure which is 160m long with a water depth of 39m. 

In 1952 when a huge earthquake hit the island the roof off Melissani lake fell in which now creates wonderful colours on the lake, which constantly change as the sunlight falls on it. 

                              

I recommend that anyone visiting any of the ionian Islands takes a trip to kefalonia to see the idyllic location.
