The Blue Cave in Croatia (Modra Špilja) is one of the country’s most mesmerizing natural wonders, famous for its ethereal blue light that fills the cavern during certain hours of the day.
This spectacular phenomenon occurs when sunlight reflects through the sea floor and illuminates the white limestone bedrock, creating a glowing aquamarine hue that captivates every visitor.
Located on Biševo Island, just off Vis Island — the furthest inhabited island in Croatia — the Blue Cave is about 40 nautical miles from Trogir (around a 1 hour and 30-minute boat ride, depending on weather conditions).
Joining a Blue Cave boat tour from Trogir is one of the best ways to explore this Adriatic treasure.
Most tours begin early in the morning and include additional stops at nearby islands such as Hvar, Vis, and the Pakleni Islands. Upon arrival at Biševo Island, visitors transfer to small wooden boats, as the cave’s entrance is only 1.5 meters high and 2.5 meters wide — too narrow for larger vessels. Once inside, prepare to be amazed as the sunlight filters through the underwater opening, flooding the cave in glowing blue light that seems almost magical.
✨ Fun Fact: The best time to visit the Blue Cave is between 09:00 am and 12:00 pm, when the sunlight hits the sea at the perfect angle for the most vibrant colors.
You can reach the Blue Cave by organized boat tours from Trogir, Split, Hvar, or Vis.
Tours typically operate from May to October, when sea conditions are calmest and the Adriatic is at its most inviting.
A typical Blue Cave day tour from Trogir includes:
🚤 A scenic speedboat ride across the Dalmatian archipelago
⛵ Transfer to a small cave boat at Biševo Island
🏝️ Stops at other highlights like Komiža, Stiniva Bay, and Hvar Town
🌞 Free time for swimming, snorkeling, or lunch
