The Magic of the Dubrovnik Blue Cave

A journey to the Blue Cave on Koločep Island is the quintessential Dubrovnik sea adventure. Located within the stunning Elaphiti archipelago, this natural phenomenon occurs when sunlight reflects through the water and off the white limestone floor, illuminating the cavern in a brilliant, neon blue glow. Most tours combine this mesmerizing swim with visits to the 'Three Green Caves', the sandy shores of Sunj Beach on Lopud Island, and panoramic views of the Dubrovnik City Walls from the water. Whether you choose a high-speed adventure or a relaxed full-day cruise, these experiences offer a perfect escape from the bustling Old Town streets into the refreshing embrace of the Adriatic.

Great Experience

The boat ride can be a bit bumpy so be prepared, but the caves are incredible. We loved the snorkeling at the Three Green Caves even more than the Blue Cave!

Private Tour is Worth It

We booked a private speedboat for our family. It was more expensive but having the boat to ourselves and choosing our own pace was amazing. Highly recommend.

Beautiful Islands

The Elaphiti islands are stunning. We had enough time at each stop. Only wish we could have stayed at the sandy beach longer!
