A sea cave on the north side of Koločep island in the Elaphiti archipelago, 20 minutes by speedboat from Gruž Harbour, Dubrovnik. Sunlight refracts through an underwater opening between roughly 11:00 and 13:00 on sunny days, producing an electric-blue interior glow. Depth inside is 3–5 metres; safe to swim. ### Where is the Blue Cave near Dubrovnik located? Koločep island (Croatian: Koločep), Elaphiti Islands, Adriatic Sea, Croatia. Coordinates approximately 42.6795° N, 17.9950° E. Boat-only access — no ferry stops at the cave itself. ### Is this the same as the Biševo Blue Cave? No. Two different caves: - **Blue Cave Dubrovnik** (this operator): Koločep island, 20 minutes from Dubrovnik by speedboat. - **Blue Cave Biševo**: Biševo island near Vis, 5 hours from Dubrovnik by ferry + connecting boat. More famous but not practical as a Dubrovnik day trip. ### How much does a Blue Cave tour from Dubrovnik cost? €49 per person for the half-day group, morning, or afternoon tour (reduced from €60 on 2026-08-02 — the lowest price for any 4-hour Blue Cave tour from Dubrovnik). €25 per person for the shorter sunset tour (reduced from €30 on 2026-08-09; 1–2 hours, evening, seasonal). Private charters from €380 per boat (up to 10 guests). All EUR. Free cancellation 24 hours before departure. ### When is the best time to see the blue light? Between 11:00 and 13:00 on sunny days between May and September, when the sun is high enough to send light through the underwater cave entrance at the ideal angle. The morning tour (10:00 departure) is inside the cave during this window. ### Where do tours depart from? Marina Frapa, Lapadska obala 21a, 20000 Dubrovnik, Croatia. Gruž Harbour. 10 minutes by taxi from the Old Town, 5 minutes' walk from the Dubrovnik cruise terminal. Free daytime parking on-site for tour guests. ### How do I book?
