Melissani Cave in Greece, Europe :
Greece has one of the most beautiful and hidden Caves in the world. This cave has a small lake present in it and the water of that lake is so pure that even a boat rowing on it , looks like it’s flying in the air due to its water being crystal clear.
But the bad news related to this cave is that it is believed that the cave is named after a nymph, who committed suicide by jumping in the lake because the one she loved didn’t love her back.
But you must visit this awesome place if you ever go to Greece and take as many pictures as you can because it is a place worth remembering.
