12 Stunning Natural Swimming Pools

Blue Grotto, Capri

Blue Grotto, Capri

This beautiful cave is located on Capri Island in Italy. The water is as blue as you see it in the photo, which is due to sunlight coming through another opening in the cave and reflecting off of the water surface. The grotto was once used as a private bath by emperors Augustus and Tiberius. (Image source)
