Blue Cave Croatia – What You Should Know | Discover the Magic of the Blue Cave

Hidden on the small island of Biševo, near Vis, the Blue Cave (Modra špilja) is one of Croatia’s most stunning natural wonders.
Famous for its glowing aquamarine light, the cave amazes visitors as sunlight enters through an underwater opening. The rays reflect off the white limestone seabed, filling the interior with a soft, surreal blue glow. It’s a natural show you’ll remember forever.

Why You Should Visit the Blue Cave

🌊 A Unique Natural Phenomenon

Between 11:00 a.m. and 12:00 p.m., sunlight reaches the perfect angle. It reflects under the sea and makes the cave sparkle with an incredible blue light.

🏝️ A Remote Adriatic Gem

The cave lies about 40 nautical miles from Trogir, near the island of Vis, Croatia’s most remote inhabited island. The area is peaceful, wild, and filled with unspoiled beauty.

🚤 An Adventure by Sea

A visit to the Blue Cave is often part of an island-hopping boat trip. You can stop at hidden coves, charming fishing villages, and crystal-clear swimming spots along the way.

Your Boat Excursion from Trogir and Split

⏱️ How Long It Takes

The trip takes around 1 hour and 30 minutes by speedboat, depending on weather conditions.

📍 Getting There

You can reach the cave from Trogir, Split, Hvar, or Vis. Most tours depart early in the morning to reach the cave before the crowds.

🛶 Entering the Cave

When you arrive at Biševo, you’ll switch to a small wooden boat. The entrance to the cave is only 1.5 meters high and 2.5 meters wide, so smaller boats are the only way inside.
