Blue Grotto Capri: Frequently Asked Questions

The Blue Grotto (Grotta Azzurra) is a sea cave on Capri whose water glows an intense blue. Sunlight enters through a large opening below the surface; the water absorbs the red light and lets blue through, so the whole cave fills with azure light and silvery reflections.

Plan for about 18 to 19 euros per person, paid in cash at the floating ticket office by the cave. That combines a cave-entrance ticket and the rowboat transport. The exact amount is set locally and can change, so treat it as a guide and carry cash.

It varies by tour. On many boat trips the grotto entry is an optional add-on you pay on the day; on some it is already included. Check the individual tour listing before booking so the on-the-day cost is clear.

Most visitors arrive on a boat tour that sails from Sorrento, Naples, Positano or Capri's Marina Grande and stops at the cave as part of an island cruise. You can also take a ferry to Capri and reach the grotto by local boat or by land from Anacapri.

Yes, often. The entrance is barely a metre high above the water, so rough seas, high winds or high tide make it impassable and it closes with little notice. It is also largely closed in winter and always closed on 25 December and 1 January.

The rowboat stays inside for about five minutes. The experience is short by design, so much of the time is spent reaching the cave and waiting in the boat queue rather than inside.

You can visit independently by reaching Anacapri and going down to the cave by land, or by taking a local boat from Marina Grande. Many people find a guided boat tour simpler because it handles the timing, the cruise and often the tickets.

Roughly 9:00 AM to 5:00 PM, weather permitting. Hours shorten outside summer and access can stop at any time if the sea picks up, so aim for a calm morning.

Late morning to early afternoon on a sunny day, when the sun is high and the underwater light is strongest. Earlier arrivals also face shorter boat queues.

Late spring through early autumn offers the calmest seas and the most reliable opening. July and August are busiest, with the longest queues; May, June and September balance good weather with smaller crowds.

In quiet periods you may wait under an hour on the water. At the height of summer the boat queue to enter can reach up to two hours, so start early.

Not during opening hours. Swimming is not permitted while the rowboats are operating. Some visitors swim near the entrance outside those hours, but that is at your own risk and outside the official visit.

No. Reaching the water by land involves stairs, and entry requires transferring into a low, unsteady rowboat and lying flat. It is not suitable for wheelchairs or strollers, or for anyone with significant mobility limits.

Older children usually manage the rowboat well, but the transfer into a small moving boat and the need to lie flat make it awkward for babies and very young children. Consider a wider island boat tour if you are travelling with little ones.

Wear light clothing you can move in, bring a hat and sun protection for the open boat, and carry cash for entry and a tip. Secure phones and cameras, as the rowboat is cramped and moves.

The open transfer and the swell at the cave mouth can be challenging if you are prone to seasickness. Take a remedy before you sail and choose a calm-sea day. A larger tour boat rides more steadily than the small rowboat.

A small tip is customary for the boatman who rows you in and often sings inside the cave. Keep a little cash aside for it alongside the entry fee.

Yes. From Anacapri you can walk down Via Pagliaro and Via Grotta Azzurra, about 3.5 km, or take the local bus from Piazza della Pace and then the stairs to the water, where you join the rowboat queue.

It sits on the water right by the cave entrance. You buy the cave ticket and pay for the rowboat there, in cash, before entering.

Yes, plan to pay in cash at the floating ticket office. Card payment is not reliable at the cave, so bring enough euros for the entry and a tip.

If the sea is too rough, the rowboats do not run and you cannot enter. Boat tours usually continue around the island's coast and other sights, so the day is not wasted, but the cave visit itself may not happen.

Refund rules depend on the operator and on whether grotto entry was a separate add-on. Check the cancellation and closure terms on your tour listing before you pay, so you know where you stand if the sea closes the cave.

The cavern is roughly 60 metres long and 25 metres wide. Despite the size inside, the sea-level entrance is tiny, which is why access is by small rowboat only.

The mouth is about two metres wide but only around one metre high above the water. Passengers lie flat in the rowboat so the boatman can guide it through.

A boat tour adds a scenic island cruise and usually smoother logistics, while a land visit from Anacapri can be cheaper and lets you go at your own pace. Sea conditions decide entry either way.

Private boats offer the most flexibility and shortest waits but cost more; small-group tours balance price and pace; larger day trips from the mainland are the most economical and cover the most ground. Pick by budget and how much you value a personal pace.

Yes. Many island boat tours pass the Faraglioni sea stacks and other grottoes, and a land visit pairs naturally with Anacapri, Monte Solaro and the town. Full-day trips often combine several of these.

For many the light inside is unforgettable, but the visit is brief and depends on the weather and queues. Going in with realistic expectations, on a calm morning, gives the best chance of a memorable trip.

In peak summer, popular boat tours sell out days ahead, so book several days in advance for July and August. In shoulder season a day or two is usually enough, though calm-weather days fill quickly.

It was used by the Romans as a marine grotto linked to Emperor Tiberius, then known locally for centuries before being brought to wider fame in 1826 by the writer August Kopisch. You can read the full story on the history page.

Yes. Capri also has the Green Grotto and the White Grotto, among others, and many boat tours pass several of them on a coastal loop around the island.

You can, but the rowboat moves and the light is low, so photos are hit or miss. Keep your camera or phone secured with a strap and expect a few quick shots rather than a careful set-up.
