We highly recommend this excellent, authentic Italian restaurant that is up in the mountain overlooking the beautiful city of Positano. We recommend going during sunset and they have a shuttle service to take you to and from your hotel.
Take a ferry over to Capri for the day to enjoy some great shops and restaurants. There is a chairlift service in Anacapri to the highest point on the island called Monte Solar with 360 views of the Mediterranean that is breathtaking. Villa San Michele is an incredible museum worth checking out if you do make it over there. Want to get in the water? Check out the Blue Grotto or "Grotta Azzurra" in Italian.
Looking for a night out with some music and dancing? Check out Music on the Rocks located on the beach in Positano.
