Blue Cave Croatia: how to get there, price and best time (2026 Guide)

Dubrovnik aside, the Blue Cave on Biševo is the most photographed sight in Croatia. And yet few travellers arrive having done their homework: they confuse the Blue Cave with the Green Cave, think it can be visited from Dubrovnik (it can't – that's a different one), or turn up in July at four in the afternoon to find the cave closed.

This guide explains everything you need to know to plan your visit properly: exactly where it is, how to get there from each city on the Dalmatian coast, how much entry costs in 2026, what time you should be inside to see the famous blue glow, and which other stops are worth it on the same day.

We've been answering questions about Croatia since 2005 and, since 2014, organising Blue Cave tours for travellers. Here's what works and what doesn't.

What the Blue Cave is and why it's special

The Blue Cave (Modra špilja in Croatian, Blue Cave in English) is a sea cave on the small island of Biševo, about 5 nautical miles south-west of the island of Vis. At certain times of day — when the sun strikes an underwater opening at just the right angle — the light reflects off the limestone seabed and bathes the whole cave in an unreal silvery blue. It's one of those places where photos don't do it justice: it's hard to believe water can look lit from within.

The cave is about 24 metres long and 12 wide, with a narrow entrance you have to duck through inside the boat. It has been open to the public since 1884, when part of the entrance was blasted to allow access by boat. Since then it has been strictly protected: no motors allowed inside, no swimming, and the only boats permitted are small wooden boats with a local boatman who rows you inside.

The visit inside lasts between 5 and 15 minutes. Short, but enough.

Where exactly the Blue Cave is

The Blue Cave is on Biševo island, a small 6 km² island with barely twenty inhabitants, next to the island of Vis in the central Dalmatian archipelago. The access port is called Mezoporat and it's where all the tours dock before you board the small boats that go into the cave.

Important: don't confuse the Blue Cave on Biševo with the so-called 'blue cave' on the island of Koločep, near Dubrovnik. They're different caves. The real, famous Blue Cave — the one on all the postcards — is on Biševo, and there are no direct tours from Dubrovnik because it's more than 200 km away.

How to get to the Blue Cave

You can only get there by sea. There's no direct ferry, airport or bridge. These are your real options:

From Split (the most popular option)

Split is the usual departure point. The crossing by motorboat takes between 1 hour 15 minutes and 2 hours, depending on the boat and sea conditions. Almost all tours leave around 7:00-8:30 in the morning to reach Biševo before the crowds and with the best light inside the cave.

Besides the cave, the classic day itinerary from Split includes Stiniva Bay (on Vis), the Blue Lagoon at Budikovac, Palmižana Bay in the Pakleni Islands and Hvar town. It's a long day — 10 to 11 hours in total — but it's worth it because you use the same journey to see five islands.

Our Blue Cave and 5 Islands tour from Split follows exactly this route.

From Trogir

Trogir is 30 km west of Split and works as a practical alternative. The sailing time to Biševo is very similar (1h30-2h) and so is the itinerary. The advantage is avoiding Split's traffic and boarding at a quieter harbour. If you're staying in Trogir, central Split, Podstrana or Kaštela, leaving from Trogir is often more convenient.

This option is available on our Blue Cave and 5 Islands tour from Trogir.

From Hvar

Hvar is, in fact, the closest point to the Blue Cave. The crossing takes around 1 hour, which means more time enjoying the stops and less time out at sea. That's why, if you're staying in Hvar for a night or two, it's much better to do the tour from there rather than from Split.

The itinerary from Hvar usually includes the Blue Cave, the Green Cave (on Ravnik island, 10 minutes from Biševo), Medvidina Cave, Stiniva Bay, the fishing village of Komiža and a stop in the Pakleni Islands on the way back.

Our Blue Cave and 3 Islands tour from Hvar covers this route in 8 hours, departing around 10:30.

What about from Dubrovnik?

There are no day trips to the Blue Cave from Dubrovnik. The actual distance (over 200 km as the crow flies) makes it impossible in a single day. If you're in Dubrovnik and want to see the Blue Cave, you have two options: change part of your route to spend a night in Split or Hvar and go from there, or visit the Elafiti Islands from Dubrovnik, a beautiful alternative with beaches, caves and picturesque villages, though without Biševo's light phenomenon.

Can you go independently?

Technically yes, but almost nobody recommends it. The DIY route involves:

1. Jadrolinija ferry from Split to Vis town (~2h15).
2. Bus or taxi from Vis to Komiža (about 15 km).
3. Water taxi from Komiža to Mezoporat, on Biševo.
4. Queue at the Mezoporat ticket office and a small boat into the cave.

The problem isn't the money — it usually works out about the same or even more expensive than a tour — but the logistics: if one leg is delayed or you miss the ferry back, you're stuck on Vis for the night. For a short, stress-free day, a guided tour is almost always the best option.

Price: entry and tour

Two separate costs that are important to tell apart:

1. Blue Cave entry (compulsory payment at Mezoporat):

• Low season (April, May, October): 12 € per adult
• High season (June-September): 18-24 € per adult
• Children under 7: free
• Important: paid in cash in euros. Cards are rarely accepted.

This entry fee isn't usually included in the tour price and has to be paid on the spot before you board the rowing boat that goes into the cave.

2. Tour price:

• Group day tour from Split: 100-130 € per person (entry and food not included)
• Tour from Hvar: 90-110 € per person
• Tour from Trogir: similar to Split
• Private tour for up to 6 people: from 600 € for the whole boat (~100 €/person with 6 on board)
• Private tour for up to 12 people: from approximately 900 € for the whole boat

If you're after an unhurried experience with a flexible itinerary, the private option pays off from 5-6 people. There are two formats in our range: the private tour for up to 6 people and the private tour for up to 12 people.

Best time to visit the Blue Cave

The time of day you go completely changes the experience.

The magic window: 11:00 to 13:00. The sun has to be high enough for its rays to pass through the underwater opening and bounce off the seabed. Before 10:00 the light is too oblique and the blue looks much duller. After 14:00 the sun starts to drop on the other side and the effect practically disappears.

That's why all tours plan the day to enter the cave during this window. If you can choose, going in around 11:30-12:00 usually gives the best blue.

Other factors that affect the experience:

• Calm sea: when there are waves, access to the cave is suspended because the boats can't get through the narrow entrance safely. This happens several times a month, especially in spring and autumn. A good tour will refund you or change the date at no cost if the cave is inaccessible.
• Cloud cover: if the sky is overcast, the effect is weaker. Sunny days give the classic electric blue.
• Crowds: between 11:30 and 13:00 there can be a queue of boats waiting to go in. The usual wait is 15-30 minutes.

Best time of year

May-June and September are the ideal months: warm water (20-24°C), the best light, fewer people than in August, more reasonable prices and settled weather.

July and August have the warmest sea (25-26°C) but are also the busiest and most expensive months. If you're going in August, book your tour at least two weeks ahead and set off early to get into the cave before 12:00.

April and October are shoulder months: fewer crowds and low prices, but the sea tends to be rougher and cancellations due to waves are more likely. If that's when you're travelling, make sure you have a spare day in your itinerary in case you need to reschedule.

From November to March many tours don't run because of the weather and because Biševo is small and access to the cave in winter is very irregular.

What to see nearby: make the most of the day

Spending 10 hours just to see a cave for 10 minutes wouldn't make sense. That's why all tours include several stops to round off the day:

• Stiniva Bay (Vis island): an incredibly narrow cove sheltered by two vertical cliffs that almost close at the entrance. Voted best beach in Europe in 2016. You can only reach it by sea or on a 40-minute walk down a steep path.
• Green Cave (Ravnik island): bigger than the Blue Cave, with an opening in the roof through which light enters, creating green reflections. Here you can swim inside.
• Komiža: a fishing village on the island of Vis, with traditional architecture, restaurants serving fresh fish and one of the most authentic old towns in Dalmatia. Some scenes from Mamma Mia 2 were filmed here.
• Blue Lagoon at Budikovac: a sheltered cove with turquoise water, perfect for snorkelling and a swim between stops.
• Palmižana Bay (Pakleni Islands): an idyllic setting opposite Hvar town, very popular for lunch at the beach restaurants.
• Hvar town: the final stop on most tours from Split. Free time for lunch, a stroll around the Old Town and a climb up to the fortress.

Practical tips

• Bring cash in euros for the cave entry (20-25 € per person is usually enough).
• Sun cream and a cap: the boats have little shade, especially the RIBs.
• Quick-drying clothes: you'll get wet getting on and off the boat. Swimwear underneath and a light T-shirt is the ideal combo.
• If you get seasick, take a travel-sickness tablet 30 minutes before boarding. The Split-Biševo crossing can be bumpy when it's windy.
• Set your phone camera to HDR or auto mode and raise the exposure by one step. Inside the cave the light is deceptive and many photos come out dark.
• Don't try to get to Biševo independently if your flight leaves Split in less than 48 hours. If there's a storm or the ferry is delayed, you could be stranded on Vis overnight.
• Always check that your tour gives a 100% refund if the cave is closed due to sea conditions. Not all of them do. Ours do.

Blue Cave FAQ

How long does the visit inside the cave last?

Between 5 and 15 minutes. It's short by design: only a few boats go in at a time, to protect the phenomenon and keep visitors rotating.

Can you swim inside the Blue Cave?

No. Swimming is strictly forbidden to protect the balance of light and the seabed. If you want to swim in sunlit waters, the Green Cave (on the neighbouring island of Ravnik) does allow it.

Is Croatia's Blue Cave the same as the one in Capri?

No, they are different caves. The one in Capri (Italy) has a similar blue light effect, but it is smaller and much busier. Visitors who have seen both tend to prefer the Croatian one for being larger and more spectacular.

Is it suitable for children?

Yes, although full-day tours (10-11 hours on a boat) can be tiring for children under 6-7. Not recommended for pregnant women or people with back problems, because of the waves.

What happens if the weather is bad on the day of my tour?

If the cave is closed due to rough seas, a good operator will refund 100% or change the date free of charge. Always check this policy before booking.

How much does the tour cost in total per person (tour + entrance)?

Between 110 € and 160 € per person, depending on the departure point and season. Included: speedboat transfer, skipper, island stops. Not included: cave entrance (12-24 €), food and drinks.

Can I reach the Blue Cave from Dubrovnik in a day?

No. The distance makes it impossible. From Dubrovnik the best alternative is the Elafiti Islands, another lovely option with beaches and authentic villages, but without the light phenomenon.

Do I need to book in advance?

In July and August, yes, at least 1-2 weeks ahead. In May, June and September 3-5 days is usually enough. In low season you can book the day before, weather permitting.
