A blue grotto or cave is a natural phenomenon wherein the sea water reflects off natural light on to the surrounding area resulting in a spectacular blue hue – for both the water and the walls of the cave. The effect that you can view up close is fantastic and absolutely transfixing.

The Blue Grotto at Capri is usually considered the most famous of them all; however it is not the only such cave. There are many other beautiful blue grottoes in the world, and incidentally quite a few of them are located in the coastal regions of Italy and Greece.

Travelerati presents you a list of the 11 Most Breathtaking Blue Grottoes and Sea Caves  that emanate a magical effect.

A formation of many interrelated caves over the sea makes up the Blues Caves in Paxos. The country of Greece is associated with many mythological tales of gods and goddesses, with Poseidon being one of them.

The region of Paxos itself has its origin related to this Greek god. It is believed that he struck the tip of Corfu with his trident, and thereby separated the landmass which forms Paxos.

The western side of Paxos has numerous cave formations which reflect the natural light from the sea surface off their walls. The area is easily accessible through the many large boats that ply frequently.
