If you’re looking for a mix of adventure, privacy, and freedom on the Adriatic, renting a speedboat to visit the Blue Cave on Koločep Island is the way to go. Unlike group tours, this option lets you explore the Elaphiti Islands at your own pace — and trust us, the view of the shimmering Blue Cave from your own boat is something you’ll never forget.
Here’s how to make it happen!
The Blue Cave (Modra Špilja) is located on the southwestern side of Koločep Island, part of the Elaphiti archipelago just northwest of Dubrovnik. The cave is known for its magical glowing blue water — the result of sunlight bouncing off the white sandy seabed through a small underwater entrance.
There are many boat rental companies in Dubrovnik that offer half-day or full-day rentals, with or without a skipper. But choose the best and trustfull company.
Once you’re on the water, getting to the Blue Cave is a scenic ride that takes about 30–45 minutes depending on sea conditions and your boat’s speed.

The Blue Cave on Koločep Island is a mesmerizing natural wonder nestled along the southern coast of this peaceful Elaphiti Island, just a short boat ride from Dubrovnik. This sea cave is famed for its stunning, ethereal blue light — a magical effect created when sunlight filters through an underwater entrance and reflects off the white limestone floor beneath the crystal-clear Adriatic waters. The result is a glowing, almost surreal azure hue that fills the cave’s interior, enchanting every visitor lucky enough to swim inside.
Unlike larger and more tourist-heavy caves, Koločep’s Blue Cave offers a quieter, more intimate experience, making it a perfect spot for adventurers, snorkelers, and nature lovers who want to connect with Croatia’s pristine marine beauty. The cave can only be accessed by swimming or small boats, adding a sense of mystery and exclusivity to the visit.
Surrounded by rugged cliffs and lush Mediterranean vegetation, the Blue Cave is not just a visual spectacle but also a serene retreat from the bustling mainland, inviting visitors to soak in the magic of the Adriatic’s hidden gems.
