The island of Capri, having no natural port, was accessible only from a small beach, which was probably one of the reasons the emperor Tiberius preferred it but the need to provide berths for ships of the fleet of Misenum made it necessary to build a port. Somewhat to the west, at Point Vivara, one can still recognize the ruins of the ancient Roman port, giving direct access to the Imperial Villa of Palazzo a Mare. Today, the port is further east, and every day boats and hydrofoils go from here to other points of the Bay of Naples. Within the port there is the tourist marina, where, especially in Summer, moor many yachts and beautiful sailing boats from all over the world.
As soon as you disembark from the boat or the hydrofoil, you will find the Public Tourist Office where you can get maps and other information. From "the Piazzetta of Capri", there is the funicular which will take you, in a few minutes, to Capri center or you can go to Anacapri by bus. You can also make the trip by taxi.
