Blue Cave Croatia Tours & Travel Guide | Visit the Blue Cave on Biševo Island

Discover Croatia’s Famous Blue Cave

On Biševo Island, near Vis, lies one of Croatia’s most spectacular natural attractions — the Blue Cave (Modra Špilja). This small sea grotto glows with an otherworldly blue light, a sight that draws travelers from all over the world.

The cave is about 24 meters long and 11 meters deep, with a narrow entrance only 1.5 meters high. The magic happens between 11:00 a.m. and 12:00 p.m., when sunlight hits the white seafloor and reflects a brilliant blue glow through the water. For a few unforgettable minutes, the entire cave shimmers like liquid sapphire.

How to Visit the Blue Cave

You can reach Biševo Island only by boat. The easiest way is to join a Blue Cave tour from Split, Hvar, or Vis. These speedboat excursions usually include transport, the cave entry ticket, and visits to nearby attractions.

Once you arrive at Mezoporat Bay, you’ll check in at the ticket office and wait for your turn to enter. Grab a drink at the nearby café while you wait. When your group is called, a small wooden boat will take you inside the cave. Within seconds, you’re surrounded by glowing blue light — a truly unforgettable moment.
