The Blue Grotto (Grotta Azzurra) is one of the most famous attractions on the beautiful island of Capri, located in Italy’s Bay of Naples. This unique sea cave gets its name from the bright blue light filtering through the water by way of an opening below sea level. To enter the cave, visitors board a small rowboat and duck as they enter through a low opening. Once inside the cave, you’ll marvel at the glowing turquoise light.
A visit to the Blue Grotto is a must for visitors on a day trip or shore excursion from the Amalfi Coast, Naples, or Sorrento. You can reach the cave by water or land, but to enter the cave, you must board an official rowboat. Due to the high number of visitors, wait times can stretch for hours, though passengers of private boat tours are often given precedence. Book your boat transfer to and from the Blue Grotto in advance to avoid long lines, or reserve a private tour with a boat ride around Capri and the Faraglioni rock formations.
Things to Know Before You Go
- At the cave entrance, you must purchase a ticket from the floating ticket office and board a rowboat to enter. This is included in most boat tours.
- Due to the low cave entrance, the Blue Grotto is only open when weather conditions permit.
- You’ll have to wait to enter the cave aboard small, open-air rowboats, so bring a hat and sunblock.
- The journey to the Blue Grotto is not recommended for those who suffer from seasickness.
- Once inside the cave, many rowboat skippers will treat you to a serenade for a small tip.
How to Get to the Blue Grotto
You can reach the Blue Grotto by sea from the Marina Grande port or by land from the town of Anacapri.
When to Get There
The cave is most crowded in summer and during the midday hours, so plan to visit first thing in the morning to avoid a long wait to enter. Note that the Blue Grotto is open only when sea conditions permit, so when the waters are rough or there are high winds, the cave may close with no advance warning.
Capri by Land
The Blue Grotto can only be visited by sea, but the island of Capri has a number of attractions on land, as well. Take an island tour of Villa San Michele, with its sweeping views over the Mediterranean, the lush Gardens of Augustus, and the 14th-century Charterhouse of San Giacomo.
