Blue Cave Tour from Split: Everything You Need to Know (2026)

What Is the Blue Cave?

The Blue Cave (Modra špilja) is a sea cave on the island of Biševo, about 90km south of Split. Inside the cave, sunlight enters through an underwater opening and reflects off the white limestone seabed, filling the cave with an electric blue glow that has no equivalent anywhere in the Mediterranean.

It lasts about 10 minutes. Those 10 minutes are extraordinary.

The best light is between 11am and noon when the sun is directly overhead. Every tour from Split is timed to arrive during this window.

How to Get to the Blue Cave from Split

There is no direct public transport to the Blue Cave. You need a boat tour. The cave is on a remote island — the only way to visit is by organised trip or private boat.

From Split harbour, the journey to Biševo takes approximately 2-2.5 hours each way on a standard group tour speedboat. This is why most Blue Cave tours are full-day (8-10 hours) — the travel time alone is 4-5 hours.

Types of Blue Cave Tours from Split

Standard Group Tour (Most Common)

Departs Split harbour every morning between 7-9am. Visits Blue Cave plus 4-5 other stops — typically Green Cave, Stiniva Bay on Vis, Pakleni islands, and Hvar Town. Returns to Split around 6-7pm.

Price: €70-90 per person (Blue Cave entry fee of ~€20 not always included — check when booking)

Group size: 12-100 people depending on the boat

Best for: First-time visitors, solo travellers, budget-conscious tourists

Small Group Speedboat Tour (Best Value for Quality)

Same route as the standard tour but on a smaller speedboat with 8-12 passengers. Faster travel, more flexibility on stops, better guide-to-passenger ratio.

Price: €90-120 per person

Best for: Those who want a better experience without going fully private

Private Boat Tour (Best Experience)

Hire a private boat and skipper — your group only, your route, your schedule. You still need to follow the Blue Cave entry queue system, but everything else is flexible.

Price: €500-900 for the boat (split across your group)

Best for: Groups of 4-8 people, special occasions, those who want the best possible experience

What Nobody Tells You About the Blue Cave Tour

The Queue

In July and August, boats queue to enter the Blue Cave. Your 10 minutes inside the cave might mean 30-60 minutes waiting in the sun on the boat outside. This is normal and unavoidable during peak season — but worth knowing in advance.

You Transfer to a Small Rowing Boat

The entrance to the Blue Cave is very low — about 1.5 metres above the water at ideal conditions. You transfer from your tour boat to a small rowing boat that takes you through the entrance lying down or crouching. It's part of the experience but worth knowing if you have mobility concerns.

The Light Depends on the Weather

On overcast days, the blue glow is significantly less impressive. The best Blue Cave experiences happen on cloudless days with flat seas and strong midday sun. You cannot control this — but if you have flexibility, check the forecast before booking.

The Tour Is Long

8-10 hours is a full day. Bring sunscreen (reapply throughout the day), a hat, water shoes, and more water than you think you need. The sun on an open speedboat for 8 hours is intense.

Is the Blue Cave Worth It?

Yes — unambiguously. The Blue Cave is one of the genuine natural wonders of the Mediterranean and the 10 minutes inside justify the entire day's travel. The additional stops — Stiniva Bay, the Pakleni islands, Hvar — add to a day that most visitors describe as the best of their entire trip to Croatia.

Book early in summer. This is the most popular day trip from Split and boats sell out days ahead in July and August.

Practical Tips

Book in advance: July and August — book at least 3-5 days ahead. June and September — 1-2 days is usually fine.

What to bring: Sunscreen, hat, water shoes, cash for Blue Cave entry and any restaurant stops, seasickness medication if needed.

Seasickness: The open Adriatic can be rough, especially on the return in the afternoon when the maestral wind builds. Take medication the night before if you're prone to motion sickness.
