About This Experience

A Half-Day Escape to Dubrovnik's Hidden Island Gems

Departing directly from Dubrovnik's harbour, this exhilarating speedboat excursion whisks you to the Elafiti Islands archipelago in no time at all. The star of the show is the legendary Blue Cave on Kolocep Island, a natural sea cave where sunlight penetrates the water and bounces off the sandy bottom to fill the chamber with a mesmerising, otherworldly blue radiance. It's a phenomenon that no photograph can fully capture — you simply have to experience it in person.

Beyond the Blue Cave, the tour visits the equally stunning Green Cave, offering another chance to witness nature's incredible light-and-water artistry. Between cave visits, guests are invited to slip into the sparkling Adriatic for a swim or to strap on a mask and snorkel among the fish below. The water here is famously transparent — so clear you can see every detail of the seabed several metres beneath you, making it ideal for both casual swimmers and keen snorkellers.

The tour wraps up with free time on Šunj Beach on Lopud Island, a wide, gently sloping sandy shore that feels like a well-kept secret on this predominantly rocky coastline. Grab a cocktail or a cold drink at the laid-back bar tucked into the woods, settle into the shade, and let the tranquillity of island life wash over you before the speedboat returns you to Dubrovnik. Small group sizes ensure a personal, relaxed atmosphere throughout the entire journey.

Blue Cave Speedboat Tour Dubrovnik Everything You Need to Know

Everything You Need to Know Before You Go

What to Bring & Pack

This tour is spent almost entirely on and in the water, so packing smart will make a real difference to your comfort. Lightweight, quick-dry clothing is ideal for the boat journey, and you'll definitely want your swimwear on underneath from the start — you could be in the water within the first hour. Sunscreen is absolutely non-negotiable on the open Adriatic; choose a reef-safe formula to protect the pristine marine environment you'll be swimming in.

A small dry bag or waterproof pouch is one of the most useful things you can bring, keeping your phone, camera, and valuables safe while you swim and explore the caves. The speedboat ride can feel breezy even on warm days, so a light layer for the journey out is a sensible addition. Snorkelling equipment is provided, but if you wear prescription lenses or have a preferred mask, feel free to bring your own for maximum comfort underwater.

  • Swimwear (wear it under your clothes from the start)
  • Reef-safe sunscreen, SPF 30 or higher
  • Waterproof dry bag for phone and valuables
  • Light cover-up or layer for the boat ride
  • Towel (not always provided)
  • Water shoes or sandals with grip
  • Reusable water bottle to stay hydrated

What to Expect on the Tour

After meeting your guide at Dubrovnik's Old Town Harbour and a brief safety and itinerary introduction, you'll board the speedboat and head out across open water toward the Elafiti Islands. The boat ride itself is exhilarating — the Adriatic air is fresh and the views of the coastline and islands are spectacular. Your guide will point out landmarks along the way and share stories about the history and ecology of the area, setting the scene perfectly for the adventures ahead.

The Blue Cave visit is the undisputed centrepiece of the day. You'll enter the cave by boat and have time to absorb the magical light display before swimming in the calm waters inside. The Green Cave follows, offering a different but equally captivating colour palette. After the caves, the speedboat heads to Šunj Beach on Lopud, where free time allows you to swim at your leisure, explore the beach, or enjoy refreshments at the beachside bar before heading back to Dubrovnik.

  • Board the speedboat at Dubrovnik Old Town Harbour
  • Scenic speedboat ride to Kolocep Island
  • Enter and explore the glowing Blue Cave
  • Visit the Green Cave and swim in vivid turquoise water
  • Snorkelling stop in crystal-clear open water
  • Free time on Šunj sandy beach, Lopud Island
  • Return speedboat ride back to Dubrovnik

Good to Know Before You Book

The caves are natural formations and access can occasionally be affected by sea conditions, swell, or wind. On days when entry is not safe, your guide will offer the best available alternative — this is a standard caveat for any cave-visiting boat tour in the Adriatic and is entirely outside the operator's control. It's worth booking your tour for the middle of your stay in Dubrovnik rather than the last day, giving flexibility in case of a rare weather-related reschedule.

Motion sickness is worth considering if you're sensitive, as the open-water speedboat legs can be lively in choppy conditions. Take medication before departure if needed. Children are welcome, and the easy difficulty rating makes this genuinely suitable for most ages and fitness levels. Tips for the guide are not included in the price but are warmly appreciated. Confirm your exact meeting point and departure time when you receive your booking confirmation, as these can vary slightly by season.

  • Cave access depends on sea conditions — check weather forecasts
  • Book mid-trip not on your final day, in case of rescheduling
  • Take seasickness medication before departure if prone to motion sickness
  • Snorkel gear is provided — no need to hire separately
  • Bring cash for drinks at the Šunj beach bar (card not always accepted)
  • Arrive at the meeting point at least 10–15 minutes early
  • Photography inside the Blue Cave is stunning — keep your camera in a dry bag until then

★★★★★

"Absolutely the highlight of our entire Croatia trip. The speedboat skimmed across crystal-clear water and arriving at the Blue Cave felt genuinely magical — that electric blue glow inside is something photos simply cannot capture. Our guide Marko was knowledgeable, funny, and made sure everyone felt safe at every stop. We also loved the swimming break at the Green Cave and the quick explore of Korčula's old town."

"We booked this as a surprise for my partner's birthday and it completely exceeded every expectation. The small group size meant we never felt like we were on a crowded tourist conveyor belt, and the boat itself was comfortable and fast. Seeing the Elafiti Islands from the water gave us a totally different perspective from anything we'd seen on land. We would book this again without a second thought."

"Really wonderful day out from Dubrovnik — the cave itself is breathtaking and worth every cent. I'm dropping one star only because the Šipan stop felt a little rushed and I could have happily spent another hour there. That said, the guide was excellent, the snorkeling spots were pristine, and the on-board snacks and water were a nice touch. Definitely recommend bringing an underwater camera."

"I've done several island boat tours around the Mediterranean and this one ranks right at the top. The route cleverly mixes dramatic sea caves, charming island villages, and open-water swimming so the day never drags. Our skipper timed the Blue Cave visit perfectly to hit the best light around midday. If you're visiting Dubrovnik and love the sea, this excursion is genuinely unmissable."

FAQ

Blue Cave Speedboat Tour Dubrovnik Frequently Asked Questions

Everything you need to know before you climb aboard — common questions answered so you can book with total confidence.

The Blue Cave and Elafiti Islands Speedboat Tour from Dubrovnik includes round-trip transport by private speedboat, a certified English-speaking skipper-guide, entrance fees to the Blue Cave on Biševo, and stops at the Green Cave, Stiniva Cove, and at least two of the Elafiti Islands — typically Šipan and Lopud. Snorkeling masks, fins, and safety equipment are provided on board, and most departures also include bottled water and light refreshments. Lunch is not included but there is time to eat at a local konoba on one of the island stops.
The full-day excursion typically runs around 10 to 12 hours, departing from Dubrovnik's Gruž harbour early in the morning — usually between 7:00 and 8:00 am — and returning by early evening. The early start is intentional: it lets the boat reach the Blue Cave before the midday crowds and catch the optimal light inside the cave. Exact departure times are confirmed in your voucher after booking.
Yes, families with children are welcome and the tour is generally suitable for kids aged six and above. Life jackets in children's sizes are carried on board, and the guide will always brief the group on safety before any swimming stop. Non-swimmers can still enjoy every cave visit and island walk — swimming is optional at all stops. If anyone in your group has limited mobility or serious motion-sickness concerns, it's worth contacting the operator before booking, as the open Adriatic can be choppy on windy days.
Pack a swimsuit, towel, sunscreen (reef-safe is appreciated), sunglasses, and a light cover-up for the island village stops. Sturdy sandals or water shoes are more practical than flip-flops on rocky beaches and boat boarding steps. A small dry bag or waterproof phone case is strongly recommended because sea spray is common at higher speeds. Bring some euros in cash for lunch, a coffee, or any souvenirs on the islands.
Safety is the operator's top priority, so departures may be postponed or cancelled if weather conditions make navigation hazardous. In the event of a weather cancellation you will receive a full refund or the option to rebook on an alternative date, subject to availability. Bookings made through Viator are covered by their standard cancellation policy, which typically allows free cancellation up to 24 hours before the scheduled departure. Always check the specific terms on your booking confirmation, as cut-off times can vary by departure slot.
The tour departs from Gruž Harbour, which is roughly three kilometres west of Dubrovnik's Old Town and easily reached by local bus (lines 1a and 1b), taxi, or rideshare app in about ten minutes. If you are driving, paid public parking is available in the Gruž area, though spaces fill up quickly in peak summer months so arriving early is advisable. Your booking confirmation will include the precise pier number and a contact number for the skipper in case you have trouble locating the boat.
