Iconic Croatia Day Trip
Blue Cave Boat Tour from Split, Croatia
The Blue Cave (Modra špilja) on Biševo Island is one of Croatia's most iconic natural wonders — and seeing it from Split is a real day trip, not a quick stop. This guide walks you through what the Blue Cave actually is, how the tours from Split work, and how to pick one that fits your day.
What is the Blue Cave?
The Blue Cave (Modra špilja in Croatian) is a small sea cave on the southwest coast of Biševo Island, about 5 nautical miles off Vis. It's only ~24 meters long and ~12 meters wide — but at midday, sunlight enters through an underwater opening and reflects off the white limestone seabed, lighting the whole cave in a glowing electric blue.
You enter by small boat through a low entrance (you have to duck during higher seas). Inside, the water glows blue from below — silver fish appear black against the light, and the rock walls shimmer. It's a 10-15 minute visit on a separate small boat, with a ticket bought at the entrance (around €15-20 per person, not included in most Split tours).
Note: the Blue Cave is NOT the Blue Lagoon — that's a separate (closer) swimming spot near Šolta. Blue Cave tours from Split are full-day excursions, mostly by speedboat, because Biševo is 2-2.5 hours away. Most tours combine the cave with Vis, Stiniva Beach, the Green Cave, and the Pakleni Islands.
Why Visit the Blue Cave from Split
Bucket-list Croatian wonder
The Blue Cave is on every 'top sights in Croatia' list for a reason — the blue glow is unlike anywhere else in the Adriatic. Most visitors call it the highlight of their Croatia trip.
Five stops, one day
Tours from Split typically include the Blue Cave, the Green Cave, Stiniva Beach (voted Europe's best beach), the seaport town of Komiža on Vis, and the Pakleni Islands or Hvar Town on the way back.
Speedboat-fast
Modern RIB and catamaran speedboats reach Biševo in about 2 hours from Split — half the time of older slow boats. That leaves more time at each stop and a less rushed day overall.
Lunch in Komiža
Most tours stop for lunch in Komiža on Vis — an old fishing town with traditional konobas serving the day's catch. The meal is usually 1-1.5 hours of free time, included as a stop but paid separately.
Private Charter Boats to the Blue Cave
No fixed-schedule Blue Cave tour matches today — but these private charter boats can run the route on demand. Build your own day: cave, Vis, Stiniva, and back at your pace.

What to Expect on a Blue Cave Tour
07:30-08:30 departure from Split or Stobreč
Most Blue Cave tours leave early — the cave is best visited between 11:00 and 14:00 when the sun is overhead, so an early start is needed for the 2-hour ride.
Blue Cave entry + Green Cave
Your captain anchors near Biševo; a small local boat takes you through the cave entrance (10-15 minutes inside). Some tours also stop at the nearby Green Cave for swimming.
Stiniva Beach swim stop
Vis Island's Stiniva — a tiny cove flanked by 70m cliffs that voted Europe's best beach in 2016 — is on most itineraries. Expect 30-45 minutes of swimming and photos.
Lunch in Komiža
Old fishing port on Vis. Traditional konobas, fresh seafood, narrow stone streets. About 1-1.5 hours free time to grab lunch (own expense, usually €15-25).
Pakleni Islands / Hvar on the way back
Returning to Split, most tours stop at the Pakleni Islands or briefly in Hvar Town for one last swim or coffee. Back in Split around 18:00-19:30.
Iconic Croatia Day Trip
Honestly? Many guests prefer the Blue Lagoon
We get it — you searched for the Blue Cave because you saw the photos. They're real, the blue glow is striking, and the day on Vis is memorable. But after running both tours for years, we'd be doing you a disservice if we didn't tell you what most of our happiest guests say: when the goal is a relaxed Croatian day on the water, the Blue Lagoon tends to win.
The Blue Cave is a 15-minute look-through, weather-dependent, with a separate €15-20 entry ticket and (in summer) a 15-30 minute queue at the entrance. The boat ride is 4+ hours out of your day. The Blue Lagoon is only 30-45 minutes from Split — you spend 2-3 hours actually swimming in turquoise water, total cost is lower, and the bay stays open even when the wind picks up.
If a 'wow' photo on a fast-boat day is your priority, the Blue Cave is still the right pick. If it's a relaxed swim in postcard water with a real lunch and unhurried free time, give the Blue Lagoon a look. Both leave from Split — choose what fits your trip.
How Much Does a Blue Cave Tour Cost?
Group speedboat tours from Split start around €100-130 per adult, with kids' rates available. That's for the boat + captain + the day's route, NOT the cave entry ticket (which is €15-20 paid at the cave itself).
Private speedboat charter for up to 12 guests is the comfortable option — usually €700-1,200 for the day depending on the boat. You get the same itinerary but pick your own pace, swim spots, and lunch break.
Most tours include water, basic snacks or fruit, fuel, and the local boat fee inside the Blue Cave. They typically do NOT include lunch in Komiža or the cave entry ticket — budget another €25-45 per person.
Best Time to Visit the Blue Cave
The Blue Cave shows its glow only between roughly 11:00 and 14:00, when the sun is high enough for rays to enter through the underwater opening. Cloud cover or rough seas can dim or close the cave entirely — check the forecast.
May, June, and September are the sweet spot: warm enough to swim, calm enough seas, and far fewer queues than July-August. In peak summer, expect a 15-30 minute wait outside the cave entrance.
Insider Tips
Bring cash for the cave entry ticket — many of the local boats inside Biševo don't take cards. €20 per person covers it with a bit to spare. Also bring a quick-dry towel and reef-safe sunscreen.
If the Blue Cave is closed due to weather, tours typically substitute the Green Cave (Zelena špilja) on Ravnik island — still pretty, fully swimmable, no ticket. A few operators refund the cave portion; most don't.

Frequently Asked Questions
How long is the Blue Cave tour from Split?+
Full-day, typically 9-11 hours. Departures are around 07:30-08:30 from Split or Stobreč harbor; return is usually 18:00-19:30. The actual Blue Cave visit is only about 15 minutes — the rest of the day covers Vis, Stiniva Beach, Komiža lunch, and the Pakleni Islands or Hvar on the way back.
Is the Blue Cave entrance ticket included?+
No — almost no tour from Split includes the €15-20 Blue Cave entrance ticket. It's paid at the cave itself, in cash, to the local Biševo boat operators who run the tiny boats that take you inside. Bring euros.
What's the difference between the Blue Cave and the Blue Lagoon?+
Two completely different places. The Blue Cave is a sea cave on Biševo Island, 2+ hours from Split — a quick guided look, no swimming inside. The Blue Lagoon is a swimmable bay near Šolta, 30-45 minutes from Split — sandy bottom, hours of swim time. Many people confuse the names. If you want a beach day, that's the Blue Lagoon. If you want the iconic blue-glow cave, that's the Blue Cave.
Can the Blue Cave be closed?+
Yes — and it happens. The cave entrance is low, so it closes during high seas or strong winds (mostly bura or jugo). When the cave is closed, tours typically still run and substitute the Green Cave on Ravnik island. Most operators don't refund the cave portion if the substitution is made; a few do — ask before booking.
Is the Blue Cave tour suitable for kids?+
Yes, generally — most tours accept kids from age 3+. The boat ride is the longest part of the day, so a calm forecast matters. Kids 12+ are charged adult rates on most tours; younger kids get reduced rates or are free.
What should I bring on a Blue Cave tour?+
Cash (€20-25 per person for the cave ticket + tips), reef-safe sunscreen, a hat, a quick-dry towel, swimsuit under your clothes, water-proof phone case, and a light jacket for the speedboat ride. Lunch money for Komiža — €15-25 per person at most konobas.
