The Blue Grotto (Grotta Azzurra) is a sea cave on the northern coast of Capri, known for its intense blue light caused by sunlight passing through an underwater cavity beneath the Marina Grande shoreline. This natural effect produces a glowing blue hue inside the cave, drawing visitors from many countries. The grotto lies about 2 kilometers from the Piazzetta di Capri, the island's central square.
Visiting the Blue Grotto requires a boat trip, with access depending on weather and sea conditions. Entrance fees and boat service costs apply. The best months to visit are April through October when the sea tends to be calmer and daylight lasts longer.

What is the Blue Grotto on Capri and why is it famous?
The Blue Grotto is a natural sea cave on Capri recognized for its striking blue light caused by sunlight filtering through underwater openings beneath the cave’s entrance near Marina Grande.
This underwater illumination makes the water inside the cave glow with a deep blue tone, best seen from inside the grotto. Sunlight enters through a submerged cavity below the entrance, reflecting off the white sandy floor and lighting up the water.
The cave measures roughly 60 meters long and 25 meters wide, with a low entrance that requires visitors to board small rowboats to enter. Historically, Roman emperors such as Tiberius used the grotto as a private swimming spot, adding historical interest. Its blend of natural features and history has made it one of Capri’s most frequented sites.
When I first visited, I was struck by the way the light transformed the water into a glowing pool, almost surreal in quality.

How do I get to the Blue Grotto from Naples?
The Blue Grotto is reached via Capri Island, accessible by ferry from Naples' Molo Beverello port; from Capri town, local boats depart from Marina Grande to the grotto.
To get to Capri from Naples, take a ferry or hydrofoil from Molo Beverello port. The journey usually takes 40 to 50 minutes, with round-trip fares between EUR 20 and 30, varying by season and ferry type.
Once on Capri, you reach the Blue Grotto by boarding small wooden rowboats—called "gozzi"—that operate from Marina Grande, the island’s main harbor on the northern shore. The boat ride to the cave entrance lasts about 10 minutes, costing around EUR 14 to 18 per person round trip. Expect wait times that depend on weather and how many boats are ahead.
When I take friends here, I always suggest arriving early to avoid long lines at Marina Grande.

What are the visiting hours and best time to visit the Blue Grotto on Capri?
The Blue Grotto is open from 9:00 AM to 5:00 PM between April and October, with the best visits from late morning to early afternoon.
The cave closes in winter because rough seas and shorter daylight hours make visits unsafe. The ideal period to visit runs from April through October, when the Tyrrhenian Sea is calmer and sunlight is bright enough to create the blue illumination.
Visiting between 11:00 AM and 2:00 PM has the strongest blue light inside the cave. It’s wise to avoid weekends and afternoon hours during peak season to reduce waiting times. Weather conditions like strong winds or high waves can cause temporary closures, so check local updates on the day you plan to go.
From my observations, midweek late mornings tend to be the least crowded.

How do I enter the Blue Grotto and what should I expect inside?
Entry to the Blue Grotto is by small rowboat through a low cave entrance near Marina Grande; visitors must lie down briefly to pass inside safely.
The entrance measures about 1 meter high and 2 meters wide, so visitors board small wooden boats operated by local rowers. To enter, passengers lie back and lower themselves as the boat slides under the low opening just above sea level.
Inside, the cave extends about 60 meters with calm, clear water glowing from the blue light. The boat slowly circles inside the grotto for several minutes, giving visitors time to take in the water’s intense color and the smooth limestone walls. Photography is allowed but tricky due to low light. The cave air feels cooler and slightly damp. The whole visit lasts around 10 to 15 minutes.
I always find the silence inside the grotto striking, broken only by the gentle splash of oars and the soft murmur of voices.

What are the costs involved in visiting the Blue Grotto on Capri?
Visiting the Blue Grotto requires paying a EUR 14 per person entrance fee for the rowboat ride into the cave, plus the ferry or boat fare to Capri.
The rowboat fee is set by local authorities and covers the round-trip ride from Marina Grande to the grotto. This fee is paid in cash directly to the boatmen. Ferry or hydrofoil fares from Naples to Capri vary between EUR 20 and 30 for a round trip.
Some tour operators offer combined packages including transport and guided visits, usually starting around EUR 50 per person. I always recommend carrying cash for the boat fee since cards are rarely accepted. Be prepared for potential waiting lines during high season, which can add to the overall cost in time.

"To visit the Blue Grotto, head to Marina Grande early in the morning around 9 am when the boats start operating; the entrance fee is about 14 euros per person, and locals suggest pairing the trip with a lemon granita at Bar Tiberio on Via Roma afterward."

Are there any safety or accessibility considerations for visiting the Blue Grotto on Capri?
Access to the Blue Grotto requires boarding small rowboats and passing through a low cave entrance near Marina Grande, which may be difficult for people with mobility issues or claustrophobia.
Visitors must lie down in the boat to enter, and the ride involves some rocking on the water. The entrance is only open when sea conditions are calm; rough seas or high waves cause closures for safety.
There is no wheelchair access inside the cave, and boarding can be challenging for elderly visitors or those with limited mobility. Children should be closely supervised. Wearing non-slip shoes is recommended, and a light jacket is useful as the cave interior can feel cool.
My advice is to consider your comfort level with low spaces and boat rides before booking.

Arrive early at Marina Grande to avoid long queues and reduce wait times for the rowboat entrance. The Blue Grotto gets crowded during peak season, especially from 11:00 AM to 3:00 PM.
Check weather forecasts and sea conditions before you go, as the grotto can close suddenly if the sea is unsafe. Booking a guided tour or private boat trip often provides priority access and helpful information.
Combine your visit with a walk or cable car ride to Capri town center (Piazzetta di Capri) or a trip to nearby other Capri attractions to make the most of your day on the island.
