We took a tour around the island of Capri and stopped to see the Blue Grotto. This is a small cave nestled by the sea and when you go into the cave you are not only struck with how dark it is, but also how bright blue the water is.
The cost is about 10.50 euros per person to go into the cave. Here are the boats with people waiting to be transferred to a little row boat to get into the cave.
Here is what it looks like inside the cave....dark walls and brilliant azure blue water. It is magnifico!
