My friends and I are going to be in Sorrento for a day in late August. Instead of just swimming on the beaches, we were wondering if it was possible to hire a boat to take us around the coast so that we can swim in the open water. Most of the stuff I've found online are long and pricy excursion tours. Does anyone know the name of a company I can call ahead and make reservations? Do you think this is something I can find in a private beach club?
