Blue Grotto Tour
The top attraction on the isle of Capri, the Blue Grotto is a natural sea cave that fills with water while sunlight filtering through the entrance illuminates it in an electric blue glow. It’s an awe-inspiring sight that can be enjoyed on a boat tour with most traveling into the narrow entrance in a traditional fishing vessel with low sides. Swimming is no longer allowed as the water is often choppy with the cliff face looking at the open sea, but it’s well worth the trip.
