Ferries and hydrofoils depart daily from the Sorrento port to Capri. From April to October, ferries can be very crowded and boat tours are an excellent alternative to save time. Small groups of 10-12 people depart from Sorrento for Capri, with the option of visiting the island and taking a dip directly from the boat just offshore.

Shared boat tours from Sorrento allow you to reach Capri on a small boat, first skirting the Sorrentine coastline and then cruising around the island of Capri. Some include stops to swim directly from the boat. These boats dock at the port on Capri so passengers can explore the island on foot for about four hours before the return trip to Sorrento. These small.-group boat tours are less expensive than private tours and include extras like docking fees.

On average, boat tours from Sorrento cost about EUR 100/person. There are less expensive tours on larger boats with larger groups and without the option of stopping to swim. Other shared tours have smaller groups and more stops to swim, but may be more expensive. Keep in mind that a round-trip hydrofoil ticket from Sorrento to Capri is around EUR 40 (plus EUR 20 if you want to take a boat cruise around the island). You may find a small-group boat tour a cost-effective option for visiting Capri, especially since many offer snacks and drinks on board and transfers from your hotel to the port.
Some tours that leave first thing in the morning also include a stop at the Blue Grotto (ticket not included).

Yes, you should always book at least a few days in advance. If you are visiting in July or August, be sure to book far in advance as boat tours almost always sell out quickly.
