Visiting Capri for a full day, or even just a few hours, is certainly possible, thanks to the short ferry ride and the many Capri boat tours that leave from the Amalfi Coast area. However, most visitors fall in love with the island and want to stay much longer! If you're coming over for just a day, prioritize a boat tour or rental that will take you to places like the Blue Grotto and Faraglioni Rocks.
