Biševo · Vis archipelago, Croatia
Where the Adriatic glows electric blue
Late-morning sunlight enters an underwater opening and lights the sea inside this small cave a luminous blue. It’s one of Croatia’s most spectacular sights — and a short, magical visit you need to time right.
Why go
A natural light show, a few minutes long
The Blue Cave (Modra špilja) is a sea cave on the small island of Biševo, southwest of Vis. Around midday, sunlight passes through an opening beneath the water and reflects off the white seabed, filling the cave with an unreal blue glow.
Visitors transfer into small official boats at the entrance and glide inside for a few minutes. Most people come on a speedboat day trip from Split, Hvar or Trogir that combines the cave with Vis, Stiniva cove and the Pakleni islands — a long, beautiful day on the water.

Frequently asked questions
How much is the Blue Cave ticket?
The ticket is usually paid on site and not included in most tour prices. Published 2025 rates were around €18 in shoulder months and €24 in peak summer for adults. Check the latest prices before you go.
When is the best time to visit?
Between roughly 10:00 and 14:00 on a sunny day, when the light through the underwater opening is strongest. Late morning is usually the most intense.
Can you swim in the Blue Cave?
No. Swimming inside the cave is not allowed. Many tours include swim stops elsewhere, such as Stiniva cove, Budikovac or the Pakleni islands.
What happens if the sea is rough?
The cave closes when waves make the low entrance unsafe — a southerly swell can close it entirely. Tours usually adapt the route; check your operator’s weather policy before booking.
How long does a tour from Split take?
Most speedboat tours from Split are full-day trips of around 9–11 hours, with roughly 1.5 hours each way at sea. From Hvar the crossing is shorter.
Is it worth it for only a few minutes?
The cave visit is short, but the day around it — Vis, Stiniva, island swims — is a highlight of any Croatian holiday. Go on a clear day for the best effect.
