The Blue Grotto (Grotto Azzura) was once a marine temple during the reign of the Roman Emperor Tiberius. Located on the Island of Capri off the coast of Sorrento, the name of the sea cave derives from the unusual bright blue color of the waters, which is caused by sunlight entering the cavern through an underwater opening directly above the cave entrance. (This impressive phenomenon is best observed around noon on a sunny day).
As your rowing boat drifts through the total darkness of the outer cavern, you will suddenly find yourself bathed in the brilliant blue light of the inner grotto – it is certainly a memorable experience.
Weather permitting, tours operate all day, but demand to see The Blue Grotto is at its highest (and queues are longest) around midday.
