The blue Grotto
It is the most famous grotto on the island. it is about 60 m long and 25 m large. To visit it, you need to take a small more rowboat which passes through a very narrow entrance. For this reason you must lie down on the bottom of the boat and when the sea is rough, it is not possible to enter.
The special light effect is due to the fact that there is a second underwater entrance which is much larger than the first one. And the Special atmosphere inside the grotto is caused just by the Light passing through the underwater entrance.
Once you are inside a surrealistic sight opens in front of you: the blue colour of the tranparent water gives you the impression that you are sailing in a crystal Blue Sky.
