• With a tour boat: at Marina Grande's port, you can purchase tickets for tours of the island by sea or a roundtrip ticket to the Blue Grotto at the ticket offices of the Motoscafisti and Laser Capri charter companies. If you purchase the "Island Tour by Sea + Stop at the Grotto", the tour boat will take you on a complete tour of the entire island including a stop at the entrance to the Blue Grotto. Here you will have to disembark from your tour boat and take one of the small rowboats to enter the cave itself.

• With a private boat: if you are visiting Capri island with your own private boat and want to tour the Blue Grotto, you can anchor at the buoys near the cave and signal to one of the waiting rowboats to be picked up. You can also hire a private "gozzo" with skipper from Marina Grande. These traditional island boats carry a maximum of seven passengers (thought there are larger versions available, as well) and the rate for a two hour tour starts from EUR 200.

• Walking or by bus: from the center of Anacapri, first walk down Via Pagliaro then down Via Grotta Azzurra (3.5 km). There is also a public bus which leaves from Piazza della Pace. From the final stop, take the stairs down to the seaside where there is the queue to the rowboats. Along the stairs, there is a small concession stand (open only in summer) which sells drinks, snacks, and souvenirs.

The famous light that illuminates the inside of the cavern is at its strongest between noon and two in the afternoon, though the reflections are spectacular all through the morning hours. Avoid visiting the grotto on heavily overcast days (when the effect of the sunlight inside the cave is much less dramatic). There is often less of a wait in the afternoon (after 3:00 p.m.), but the seas can become rough resulting in the cave closing to the public.

Tickets cost EUR 18 and are purchased from the floating ticket office (EUR 12 for the rowboat).
Discounts: Children entrance under 6 years old: free. For citizens of the European Union younger than 18 entry is free, so tickets must be purchased solely for the rowboat (EUR 12). For citizens of the European Union between 18 and 25 years of age, the entry ticket is EUR 2 , for a total cost of EUR 14.
Tickets for the Blue Grotto are in addition to tickets for boat tours from Marina Grande. For boat tours by sea of the island or for a roundtrip transfer to and from the Blue Grotto, the ticket price per person is EUR 24.
The rowboat skippers who take visitors inside the grotto usually ask for a tip, though this is at the discretion of passengers.

Visitors are not allowed to swim into the grotto or dive from rowboats to swim inside the cavern. Many visitors wait until after 5:30 p.m. when the rowboats leave and the ticket office closes to swim inside. This is illegal and dangerous, as the high waves can slam swimmers against the stone of the low cave mouth.

There is no minimum age to visit the Blue Grotto, though the use of rowboats to gain access to the cave can be hard on small children and infants, as there is often a long wait under the sun.

The visit inside the grotto on rowboats lasts about five minutes. However, the wait to enter the cave can be long, reaching an hour during high season at peak times of the day. The average time for a tour of the island by sea plus a visit to the Blue Grotto is about two hours. For a simple roundtrip transfer and visit to the cave, plan for about an hour.

In case of strong winds or rough seas, entrance to the grotto will be suspended; often, the grotto will open and close a number of times on the same day when the weather is unstable. Unfortunately, it's hard to forecast closures due to weather, though if the weather forecast reports rough seas, the grotto will probably be closed. , You can check if the cave is open by looking at the signal at the top of this page, after 9 AM. The signals works from March to lat October. During the winter the Grotto is mostly closed.

In case of mild weather, the Blue Grotto is open during the winter months. That said, the grotto is often closed between November and the beginning of March due to adverse weather conditions. If you are visiting during the winter, you can check up-to-date closures at the Marina Grande port by asking at the ticket windows for Laser Capri (Pier 21) or Motoscafisti di Capri (Pier 0), or by calling the Motoscafisti di Capri pier after 9 am. If both ticket offices are closed and no one answers the telephone, the grotto is closed.

The bright azure color of the water inside the cave is due to the sunlight which enters the cavern through an underwater opening which is positioned exactly under the cave's mouth. As the light passes through the water, the red reflections are filtered out and only the blue enter the cave itself. The famous silver reflections of objects in the water are caused by tiny bubbles covering the outside of objects underwater, which causes the light to refract differently than that of the surrounding water and causes this silvery effect.

During the reign of Tiberius in Roman times, the grotto was used as a marine temple, and ancient Roman statues found here are now on display at the Casa Rossa in Anacapri. For many years afterwards, the Blue Grotto was avoided by sailors, as local legends told of spirits and demons living there. One day in 1826, however, local fisherman Angelo Ferraro accompanied German author August Kopisch and painter Ernst Fries to the cave, and their tales of its marvels have led to the grotto being one of the must-see sights on any visitor to Capri's itinerary.
