The Famed Grotto Azzure
This was the most touristy thing we did. You line up in your transport boat in front of this little cave with a floating concession stand and a bunch of row boat drivers who take you through this small hole into a beautiful cave that was said to be Tiberious' swimming pool. They sing to you while you are in there and I took some video on the camera that was really pretty cool, but I don't think it will work on the blog.
