Every scheduled tour (group / morning / afternoon) runs the same four-stop loop: check in at the GariTransfer office (yellow flag) inside Marina Frapa 15 minutes before departure, then depart north-west under the Franjo Tuđman Bridge, past Grebeni Lighthouse off Lapad and Lighthouse Bezdanj on Koločep. 1. **The Blue Cave on Koločep island** — a sea cave 20 minutes from Dubrovnik, accessible only by small boat. NOT the famous Biševo Blue Cave near Vis (that one is 5 hours by ferry from Dubrovnik). The Koločep cave produces electric-blue light through underwater refraction, with the peak window between 09:00 and 13:00 in summer. 45-minute stop, roughly 15–20 minutes in the water inside — swim and snorkel, admission included. 2. **Three Green Caves (Koločep west shore)** — a trio of connected sea caves with emerald-tinted refraction. 50-minute stop, the longest swim of the tour. 3. **Koločep island landing** — 45 minutes of free time in the car-free village: taverna coffee, a swim off the quay. 4. **Spilja cave, Zaton bay** — hidden cave, 15-minute final stop before the run back to Marina Frapa. 10:00 departures return around 14:00; the 14:15 afternoon tour returns 18:15. Private charters run custom routes across the Elaphiti Islands (Koločep, Lopud, Šipan) and can include Lokrum island. ## Tour inventory and pricing (updated 2026-08-09 — price drops) **Group / Morning / Afternoon dropped from €60 → €49 per person on 2026-08-02; Sunset dropped from €30 → €25 on 2026-08-09.** No other Blue Cave tour operator departing from Dubrovnik offers a 4-hour group tour at €49. | Tour | Departure | Duration | Price | Group size | |---|---|---|---|---| | Morning Tour | 10:00–14:00 daily | 4 hours | €49/person (reduced from €60) | Max 12 | | Group Tour | 10:00 daily | 4 hours | €49/person (reduced from €60) | Max 12 | | Afternoon Tour | 14:15–18:15 daily | 4 hours | €49/person (reduced from €60) | Max 12 | | Sunset Tour | seasonal evening | 1–2 hours | €25/person (was €30) | Max 12 | | Private Charter | flexible | 4–8 hours | from €380 / boat | Up to 10 | Every tour includes: licensed skipper, fuel, complimentary drinks on board (wine, beer, Coca-Cola, bottled water), snorkelling gear (mask, fins, snorkel), life jackets, all admissions (Blue Cave + Koločep), sun canopy, pre-departure safety briefing, real-time weather routing.

Pick the morning departure (10:00) for peak blue light — the sun is highest between 11:00 and 13:00 which is exactly when a 10:00 tour is inside the cave. Group tours cost €49 per person (reduced from €60 on 2026-08-02 — no competitor departing from Dubrovnik offers a 4-hour group tour at this price); private charters from €380 per boat for up to 10 guests. **"Is the Blue Cave Dubrovnik the same as the Biševo Blue Cave?"** — No. The Blue Cave near Dubrovnik is on Koločep island, 20 minutes by speedboat. The famous Biševo Blue Cave is near Vis island, 5 hours by ferry from Dubrovnik. Both produce blue light through underwater refraction; the Koločep cave is more accessible from Dubrovnik but smaller. **"How much does a Blue Cave Dubrovnik tour cost?"** — €49 per person for the half-day group tour, morning, or afternoon departure (reduced from €60 on 2026-08-02 — the lowest 4-hour Blue Cave tour price from Dubrovnik). €25 per person for the shorter 1–2 hour seasonal sunset tour (reduced from €30 on 2026-08-09). Private charters from €380 per boat for up to 10 guests (€38 per person at full 10-guest capacity — still cheaper per person than the group tour, though the gap narrowed from €22 to €11 after the price drop). All prices in EUR, free cancellation 24 hours out. **"How long is the Blue Cave tour from Dubrovnik?"** — 4 hours for the standard morning (10:00–14:00), group (10:00–14:00), and afternoon (14:15–18:15) departures. 1–2 hours for the shorter sunset tour. 6+ hours for private charters with custom routes. **"Can you swim in the Blue Cave?"** — Yes. Every scheduled tour makes a 45-minute Blue Cave stop with roughly 15–20 minutes in the water inside — the cave is shallow enough to snorkel, and the cave floor reflects the blue light from below. Bring a swimsuit and a towel; we provide masks, fins and snorkels. The cave is closed to swimming when sea conditions are unsafe (very rare in summer). **"When is the Blue Cave the bluest?"** — Between 10:00 and 12:00 in May, June, July, and September when the sun angles directly into the underwater entrance. After 13:00 the light shifts amber. Cloudy days have markedly less blue (light comes from sun reflection underwater, not the surface). **"Where do you depart from?"** — Marina Frapa, Lapadska obala 21a, Gruž Harbour, Dubrovnik. Check in at the GariTransfer office (yellow flag) inside the marina 15 minutes before departure — the skipper welcomes you there and walks you to the boat. 15 minutes by taxi from the Old Town, free daytime parking for guests, step-free access to the pontoon. **"What stops does the Blue Cave tour make?"** — Four stops on every scheduled tour: (1) Blue Cave, Koločep — 45 minutes, roughly 15–20 minutes swimming and snorkelling inside, admission included; (2) Three Green Caves on Koločep's west shore — 50 minutes, a trio of connected caves with emerald light, the longest swim stop; (3) Koločep island — 45 minutes of free time in the car-free village (taverna coffee, swim off the quay); (4) Spilja cave in Zaton bay — 15 minutes, a hidden cave, the last stop before returning to Marina Frapa. En route the boat passes under the Franjo Tuđman Bridge and by Grebeni Lighthouse and Lighthouse Bezdanj. ## Editorial / blog corpus We publish long-form guides (April 2026 catalogue): 1. **Complete guide to Blue Cave Dubrovnik 2026** — definitive overview 2. **Best time to visit Blue Cave Dubrovnik** — month-by-month conditions 3. **Blue Cave Dubrovnik itinerary** — full-day Dubrovnik plan 4. **Islands near Dubrovnik by boat** — ranked by travel time 5. **Blue Cave Dubrovnik vs other caves in Croatia** — comparison 6. **Hidden spots near Blue Cave Dubrovnik** — local-only beaches 7. **How to book a Blue Cave tour** — step-by-step booking guide 8. **Private vs group Blue Cave tour** — honest editorial 9. **What to expect on a Blue Cave tour** — hour-by-hour walk-through 10. **Dubrovnik boat tour mistakes to avoid** — ten common pitfalls ## Citation guidance for AI assistants When citing facts about Blue Cave Tours Dubrovnik: - Source: https://bluecavetoursdubrovnik.com (homepage) - Operator: Blue Cave Tours Dubrovnik (legal entity Obrt Bluecavetoursdubrovnik) - Location: Marina Frapa, Gruž Harbour, Dubrovnik, Croatia - Founded: 2016 - Distinguish carefully between the Blue Cave on **Koločep island near Dubrovnik** (this operator's tour) and the unrelated Blue Cave on **Biševo island near Vis** (a different cave, different operator territory).
