8 Blue Grotto Cave

For visitors that enjoy the ocean and caves, the Blue Grotto Cave in Capri, Italy is the perfect place to visit. This cave is a well-known sea cave in Capri that is off the coast of the island. It gets its name for the brilliant, glowing blue that the water gets from the light that filters in from the small entrance and the bigger hole just beneath the entrance.
