This was the best day of our trip. We had a beautiful sunny day (wear a lot of sunscreen!) The boat was beautiful and clean, the driver, Hermes, was fantastic, and the ride around Capri, and the beautiful grottos was spectacular. They serve you prosciutto and melon, soft drinks, water, or Proseco. You get to swim in the bluest (or greenest) water and explore caves and grottos. We went to an authentic seafood restaurant in Nerano for lunch at Il Cantuccio which was SO much fun. You can choose to go up to the main towns of Capri, but it can be very busy and difficult to get a taxi during high season, so we just enjoyed the boat ride and the sea. Highly recommend!!!!
