Fodor's Expert Review Grotta Azzurra

Only when the Grotta Azzurra was "discovered" in 1826, by the Polish poet August Kopisch and Swiss artist Ernest Fries, did Capri become a tourist destination. The watery cave's blue beauty became a symbol of the return to nature. In reality, the grotto had long been a local landmark. During the Roman era it had been the elegant, mosaic-decorated nymphaeum of the adjoining villa of Gradola. The water's extraordinary sapphire color is caused by a hidden opening in the rock that refracts the light. Locals say the afternoon light is best from April to June, and the morning in July and August. The Blue Grotto can be reached from Marina Grande or from the small embarkation point below Anacapri on the northwest side of the island, accessible by bus from Anacapri. You board one boat to get to the grotto, then transfer to a smaller boat that takes you inside.
