No trip to Anacapri is complete without a visit to the famous Blue Grotto. This natural sea cave is renowned for its mesmerizing blue waters, which are illuminated by sunlight passing through an underwater cavity. To enter the Blue Grotto, you'll need to board a small rowboat and lie flat as you pass through the narrow entrance. Once inside, you'll be enchanted by the ethereal blue glow that surrounds you. The cave's interior is adorned with stalactites and stalagmites, adding to its otherworldly beauty. Winter is an ideal time to visit the Blue Grotto, as there are fewer tourists, allowing for a more intimate and peaceful experience.
