No trip to Capri is complete without a visit to the famous Blue Grotto. This natural sea cave is known for its mesmerizing blue waters, created by sunlight passing through an underwater cavity. To enter the 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. The experience is truly magical and a highlight of any trip to Anacapri.
