What I did in Capri:

      Boat tour from Sorrento
      Swam in the Blue Grotto
      Swam in the Green Grotto
      Walked around the island of Capri

The boat trip from Sorrento to Capri was one of the best days during the semseter. We had a lot of fun on the boat and were able to swim in the bluest water I have ever seen! I also really liked walking around the island of Capri, and would love to go back sometime soon.
