Blue Grotto (Grotta Azzurra)
An emblematic tourist attraction, the Blue Grotto (Grotta Azzurra) is reason enough for any visitor to Naples to make the short trip across to the island of Capri. A world-famous sea cave, the Blue Grotto is perpetually filled with brilliant sapphire light, caused by sunlight entering through an underwater cavity and shining through the seawater from beneath. The cave also contains a smaller opening right at the level of the water-line, through which bright sunshine pours, and through which tourists are admitted by row-boat. Gaze in wonder at the spectral water, more light-filled than the air in the cave, and be sure to dip your hands and watch them glow an eerie silver-blue. Since row-boats entering the cave can only take a maximum of three passengers, you are ensured a private and truly unforgettable experience in the Blue Grotto, one which you will treasure for the rest of your life. Blue Grotto Tours is a popular tour company which guides trips into the mystical blue cave and has earned rave reviews from tourists. Of course, the island of Capri is beautiful and a hop across the water from Naples is worthwhile just to see the lovely landscape and experience the atmosphere of this famous island.
