The best way to see the blue grotto is to get there early. You should take the first ferrys from wherever you're staying around 8:00. You should then take the first boat tour right from the marina at Capri that goes around the island. Otherwise, you may have to wait up to 2 hours or more during the high season and anyway the bigger boat tours only wait a maximum of 45 minutes and skip it otherwise. The other important thing to note is that its actually closed due to high sea level more often than not. I experienced that the boat tour ticket agents never give you straight answer on whether or not it's expected to be open or closed for the day you want, even on the morning of, where they should have a good idea about the tides. You also have to pay 18 EUR to enter, which I think is quite a lot for spending just a couple of minutes inside. So decide for yourself if you think it's worth it and the important thing is to get there early.

Whilst many operates promote the Blue grotto, do not get trapped, it is only open when the seas are calm. They show entrance is 18 euro, that may the true but there is a big cost getting there. We were lucky to be on a boat trip to Capri & they were advised at 11 am it was open. It cost us 41 euro each to get a private bus with 14 others included entry to the cave. The entry is via small wooden boats the takes 5 plus the oarsman, you lay down, & get pull by the Oarsman through the small tunnel top being about 3 ft above sea level into a cave , there will be about 8 other boats in there, you are in & out in about a minute, Is it worth it, no, it is an experience.

The Blue Grotto in Capri is a magical and unforgettable experience. The stunning blue glow that fills the cave creates a unique atmosphere. Though the entrance is narrow, the boat ride adds excitement to the visit. I recommend going at midday for the best light show. Don't miss it if you're visiting Capri!

A potentially pretty place spoilt by overselling, excessive tourism and boatmen hassling for tips. There are nicer places on Capri that have blue water and are not spoilt by tourism. It was good to visit once but would not go again.

I admit to being a little sold on the instagram hype but it definitely wasn’t worth the money and the time. I googled before so I knew to expect a wait on the boat before getting into the rowing boats but it was close to 90 mins for 5 mins max in the grotto. I also knew the guides of the rowing boats would tell us about an “extra charge” so we firmly said no to that! When you get into the little rowing boats they take you to another boat to pay for boat fee and entry fee which was about €18 each. The guides were saying “their” charge was €20 per person!! We genuinely had no cash but I also knew it was a play but I couldn’t believe the people handing over wads of cash when they had already paid. I don’t mind a small tip but €80 for 5 mins as a tip is laughable. The grotto itself is fine. Kinda cool and looks good in pictures but it was in no way a life changing experience. I’m disappointed that we wasted two hours of our day trip to Capri on this and wouldn’t do it again.

The Blue Grotto is a unique visual experience. Very pretty. We were on a tour that included the Blue Grotto. Our tour guide warned us that the boat driver might ask for a tip, but there was no obligation to comply. The boat driver harassed us to give 5 Euro. I gave 1 and a half Euro, and he was not pleased. "This is not church!" HA! We had already paid 18 Euro each.

Although waiting time was about 1 hours but it was well worth it. Tour from capri was well organized. Visited last time in 1998. This time came with my son and daughter who missed it last time.

The Blue Grotto on Capri is of course one of the must-do attractions on the island. Whether you enjoy it or not depends on how well you plan and whether you like spending time on the water. Here’s some hints and tips. This attraction can have huge wait times and if you don’t like boats it’s better for the wait time to be on land. Many people take a guided tour which involves a boat ride from Marina Grande around the island, waiting on the sea at the entrance to the grotto (which can take hours), transferring to one of the little row boats that are small enough to enter the cave entrance, 5 mins in the grotto and then the reverse trip back. This can take half a day and of course the cost is quite high. You can cut down on time and cost by 1) going as early as possible in the morning, 2) taking the overland option. We decided on the overland option which involved a bus from Marina Grande to Capri town, a second bus from Capri town to Anacapri, and a taxi from Anacapri to the Blue Grotto jetty at 40°33'39.4"N 14°12'19.4"E. There are a number of concrete steps down to the little pier where the row boats collect you and you pay the boat owner directly in cash. You still need to wait your turn to enter the cave (involving lying flat in the boat since the entrance is really low) before your 5 mins in the beautiful grotto marveling at the iridescent luminous blue water, and then back outside again. There is actually a bus that runs from Anacapri to the Blue Grotto and back so we took that on the return journey. The entire journey from start to finish would have taken about two hours (of which most of the time was spent in line on the concrete steps down to the jetty). It’s definitely worth doing but make sure you choose the option that is right for you.

So fun! Walked a block from the central square and took the Anacapri bus ... 2 stops and a short walk down to blue grotto. Getting into the boats from land seems easier than going from boat to boat
