What is the Blue Cave in Dubrovnik?
The Blue Cave, located on Koločep Island (part of the Elaphiti Islands near Dubrovnik), is one of the region’s most magical natural wonders. This mesmerizing sea cave is named for its glowing blue interior, created when sunlight reflects through the cave’s underwater entrance, illuminating the entire space in radiant shades of blue.
The phenomenon is most intense around midday, when the sun is at its highest point — making it the perfect time to visit.

- Swim inside glowing blue waters
- Accessible only by boat or yacht
- Great for photography and Instagram moments
