The Blue Grotto is open daily from 9 am to 5 pm when weather and sea conditions permit. Boats can only enter the grotto when the sea is calm and there is no crosswind or high wave as the cave mouth is only a meter above sea level.
Unfortunately, the weather forecast can only give an indication as to whether the grotto will be open or closed. For a final decision, you have to wait until the skippers arrive at the cave entrance at 9 am to verify the weather and sea conditions and check that the cave can be entered safely. For updated information about whether the Blue Grotto is open or closed for the day, check this page.
Tickets to enter the Blue Grotto cost €14, with a discount for children.
The visit inside the grotto lasts about 5 minutes, but you can tip your skipper for additional time :)
No, it is both illegal and dangerous to swim in the grotto. That said, many people swim into the cave after it closes in the evening.
To avoid a long wait (which can reach up to two hours in high season), the best option is to leave for the grotto before 9 am so you are among the first to arrive in the morning. You can even arrive with the skippers on the first Motoscafisti boat from Marina Grande to the Blue Grotto in the morning. Midday is the most crowded time to visit the grotto.
The color is most intense inside the grotto at noon.
Yes, you can take the bus which departs from the center of Anacapri and stops near the entrance of the grotto. Take the stairs down toward the sea where you can take a rowboat inside the grotto.
No, you can only buy tickets for the boat transfer from Marina Grande to the Blue Grotto in advance. Tickets to enter the Blue Grotto must be purchased at the cave entrance upon arrival.
