If your cruise stops in Naples, they will propose a visit to the wonderful island of Capri, the jewel of the bay, if you want to get there we suggest you do it by ferry, which you can reach in just twenty minutes (in the fastest), although if you want to enjoy the charms of the area, I would recommend the tour that takes 90 minutes and allows you to see more stops.
Most of the tours to Capri are made on timetables daytime And remember that the island of Capri is subject to a rigid regulation of maritime traffic, therefore access is limited.
Capri is right in front of the Sorrentine peninsula, it is a small island, only 10 square kilometers, but millions of tourists visit it every year ... and you know, millions of people can't be wrong.
To book your ticket, if your shipping company has not already provided you with this option, you will have no problem since there are several companies that make the route and all of them have a website from which to buy your tickets. The companies that make this crossing are SNAV, NLG & Alilauro and depending on the season you can choose between up to 66 daily ferry routes. But I would recommend, due to schedule reasons, that you buy the excursion that they propose from the boat and that it will surely include a guide to show you the charms of this romantic island.
All the ferries arrive at the port of Capri, known as Marina Grande. If you are not very tired or tired of sailing, I would recommend you take a barge, in which in about 2 hours they will give you an excursion, around the island to see different scenic enclaves of the abrupt coast of Capri, such as its famous Great Grotto , idyllic place where you will enter with the barge.
