Blue Cave Boat Tour Dubrovnik

About the Blue Cave Boat Tour from Dubrovnik

This is our only group tour — every other Mala Mara experience is fully private. We run this Blue Cave boat tour Dubrovnik route because the Blue Cave, Green Cave, and Sunj Beach on Lopud combine into a half-day that consistently delivers, and offering it as a group tour means more people can experience it at an accessible price point.

The Blue Grotto is intimate, not vast. That’s what makes it work. Sunlight enters through an underwater fissure in the limestone and refracts off the white seabed, filling the chamber with this luminous aquamarine that shifts with the hour. Before noon the blue runs electric, almost violet at the edges. By mid-afternoon it softens — warmer, more teal, like light through bottle glass. I’ve watched hundreds of people try to photograph it. The phone never gets it right. Your eyes will.

After the Blue Cave, we head to the Green Cave — a different light phenomenon, where sunlight filtering through an overhead opening paints the water in vivid emerald tones. You get around 30 minutes here to swim and explore.

The final stop is Sunj Beach on the island of Lopud — a long, sandy crescent with shallow turquoise water. You get around an hour and 45 minutes of free time here to swim, sunbathe, grab a bite at one of the beachside spots, or simply relax. It’s the kind of beach that makes people rethink their afternoon plans.

What’s Included in the Blue Cave Tour

A 4-hour group tour covering the most spectacular natural sights accessible from Dubrovnik by boat. You’ll visit the Blue Cave (Blue Grotto), the Green Cave, and spend around 1 hour 45 minutes on Sunj Beach on Lopud Island. Up to 12 guests per departure. The pace is relaxed — there’s time to properly experience each stop without rushing.

Blue Cave Boat Tour Itinerary — Hour by Hour

1. Depart Old Town Port — Board below the walls. Quick safety brief, engine on, and the city falls behind.
2. Blue Cave (20-30 min) — Enter the grotto and experience the luminous blue light phenomenon. Swimming inside when conditions allow; the skipper makes the call.
3. Green Cave (30 min) — Swim beneath the emerald light filtering through the cave’s natural opening. Snorkel gear provided.
4. Sunj Beach, Lopud (~1h 45min free time) — Sandy beach, shallow water, beachside restaurants. Swim, sunbathe, explore the island, or grab a bite at your own pace.
5. Return to Old Town Port — Scenic cruise back along the coastline.

Route adjusts with wind, swell, and sea conditions. Your skipper selects the best approach in real time.

What’s Included in the Price

Skipper, fuel, full safety kit, insurance, quality snorkeling gear, fresh water, and a cooler packed with ice. Bring your own towel, drinks, and whatever you want to snack on — the cooler is there for you. Tips are welcomed, never expected.

Why Book the Blue Cave Tour Direct (Not Through Viator or GetYourGuide)

Same Blue Cave boat tour, same skipper, same boat — 25–30% cheaper when you book direct here. OTAs like Viator and GetYourGuide charge a 20–25% commission on every booking, which gets passed to you. Booking direct means:

• Lower price — you keep the OTA commission instead of paying it
• Direct WhatsApp with your skipper — no support ticket loop through a platform
• Weather cancellation: 100% refund, guaranteed — not the OTA’s reschedule-only policy
• Real-time questions answered by people who actually run the tours, not a third-party call centre

Departure Times & Meeting Point

Two departures daily, April to October: 10:00 and 14:30. The morning tour gets the strongest blue inside the cave — the sun is high and the light enters through the underwater opening at the best angle. The afternoon tour is warmer for swimming and quieter at Sunj Beach.

We leave from Old Town Port, right below the city walls next to the Ploče gate. Be there 15 minutes before departure. You’ll receive the exact meeting point on a map by email and WhatsApp as soon as you book.

Is This Tour for You?

Yes, if you: want to see the Blue Cave without giving up a whole day, are travelling with kids (we’ve had guests from age 3), have limited time in Dubrovnik, or simply want a morning or afternoon on the water with swimming stops that cruise-ship excursions skip.

Probably not, if you: are looking for the Biševo Blue Cave near Vis (a different cave, a full day from Dubrovnik), or want a boat to yourselves. For a private option, see our Elaphiti Islands private tour.

What to Bring

Swimwear, a towel, sunscreen and a hat. Water shoes help at the rocky cave entrance if you swim. Snorkel gear, fresh water and a cooler with ice are on board. Bring your own drinks and snacks for the cooler, and a card or some cash for a coffee or lunch at Sunj Beach.

Weather & Sea Conditions

We check sea conditions every morning. If the swell makes the cave unsafe to enter, we’ll contact you to move your booking or run an alternative coastal route with swimming stops. If we cancel because of weather, you receive a 100% refund of your deposit — no questions asked.
