For most visitors, a boat tour — not the ferry — is the way to actually see Capri. The ferry is cheap transport to Marina Grande, but the island's best parts sit at sea level: the Faraglioni, the grottoes and the hidden coves you can only reach by boat. A tour from Sorrento crosses in about 20–30 minutes, then circles the island so you spend the day swimming and sightseeing instead of queueing for the funicular.

The honest rule of thumb: if you only want to walk Capri town on the tightest budget, the ferry (about €40 round trip) is enough. If you want the coastline, the sea caves and a swim, the boat is the point. Two formats dominate from Sorrento — shared boats from $72 and small-group cruises capped at 8–12 guests. The Blue Grotto is a weather bonus on either: €18 cash, never included, and closed whenever the sea runs rough.
