What Makes the Blue Grotto Blue?
Excerpt from A Child’s Geography: Explore the Classical World
If you look north across the bay, you can see Mount Vesuvius off in the distance. Directly on the other side of the bay is the city of Naples. Now, if you look due west you can see an island on the distant horizon. That is the beautiful and mysterious Isle of Capri. Capri is home to the enchanting Blue Grotto. Have you ever heard of it? The Blue Grotto is a sea cave, famous for its glowing blue waters. Mysteriously, sunlight shines through an underwater cavity and illuminates the waters creating the blue glow. The cave is tricky to get into but well worth the effort. This looks like the perfect place for pirate treasure, don’t you think?
