About This Tour

A Full Day of Caves, Colour & Coastal Bliss

Set sail from Dubrovnik and head into the tranquil waters of the Elafiti archipelago aboard a comfortable boat. The journey itself is rewarding — turquoise bays, pine-covered islands, and the shimmering open Adriatic surround you before you even reach the first cave. Your knowledgeable guide will share the geology and local lore behind these extraordinary formations, making the experience as educational as it is visually stunning.

The Blue Cave on the southern coast of Koločep Island is the undisputed star of the tour. Sunlight filters through an underwater opening and reflects off the pale sandy bottom, flooding the interior with a luminous blue glow that seems almost digital in its intensity. Photographers and casual visitors alike are consistently left speechless. The Green Cave follows, offering a contrasting palette of vivid greens and teals that feel equally surreal and magical.

After the caves, the tour transitions into pure leisure. Snorkelling equipment is available so you can explore the rich underwater world at your own pace before the boat docks near Šunj Beach. This beautiful, shallow sandy beach is one of the few of its kind along the Croatian coastline, ideal for families and relaxation seekers. A bar set among the pine trees provides cool drinks and shade, giving you the perfect place to reflect on an exceptional day out.

Travel Guide

Blue Cave Dubrovnik Everything You Need to Know

Everything you need to know before you go

What to Bring & Pack

This is a full-day boat excursion that includes swimming and cave exploration, so packing smart is essential. Lightweight, quick-dry clothing is strongly recommended, and you'll want to wear your swimwear underneath your outfit to save time changing on the boat. The Adriatic sun is intense, especially when you're out on the open water, so sun protection should be at the top of your packing list.

Waterproof bags or dry pouches are a wise investment for protecting your valuables, camera, and phone during cave visits and snorkelling sessions. Footwear that can handle both the boat deck and a sandy beach is ideal — flip-flops or water shoes both work well. Pack light but pack smart, and you'll have everything you need for a comfortable, stress-free adventure.

  • Swimwear (worn under your clothes)
  • High-SPF sunscreen and lip balm
  • Lightweight cover-up or rash guard
  • Waterproof bag or dry pouch for valuables
  • Sunglasses and a wide-brim hat
  • Water bottle and light snacks
  • Flip-flops or water shoes

What to Expect on the Tour

The adventure begins at Dubrovnik's Old Port, where you board a comfortable speedboat and depart for the Elafiti Islands. The boat ride itself is scenic and refreshing, cutting through vivid blue waters as the city's historic walls fade into the distance behind you. Your guide sets the tone early — friendly, informative, and enthusiastic about sharing the secrets of this remarkable corner of the Adriatic coast.

After the cave visits, the pace slows pleasantly. The boat anchors in a sheltered bay so guests can swim and snorkel at their leisure before heading to Šunj Beach on Lopud Island. Here you'll have free time to explore the beach, take a dip in the gentle surf, or sit back with a cold drink at the beach bar in the woods. The return journey to Dubrovnik wraps up a perfectly balanced day of discovery and relaxation.

  • Board the boat at Dubrovnik Old Port and set off for the Elafiti Islands
  • Enter and explore the iconic Blue Cave on Koločep's southern coast
  • Visit the Green Cave and admire its contrasting emerald hues
  • Anchor in a clear bay for open-water swimming and snorkelling
  • Arrive at Šunj Beach on Lopud Island for free beach time
  • Enjoy drinks and relaxation at the bar nestled among the pine trees
  • Return by boat to Dubrovnik harbour

Good to Know Before You Book

This tour operates in a small-group format, which means a more personal experience and easier access to the caves without crowds. However, cave entry can depend on sea conditions — if the water is rough, the captain may adjust the route for safety. This is perfectly normal and a responsible practice; your guide will always communicate any changes clearly and offer the best available alternative.

It's worth noting that Šunj Beach has a bar but limited food options, so bringing your own snacks or eating a proper meal before departure is advisable. Motion sickness patches or tablets are recommended for anyone sensitive to boat movement, especially if seas are choppy. Book your spot in advance during the summer months, as availability fills up quickly for this popular excursion.

  • Cave entry depends on sea conditions — the captain prioritises passenger safety
  • Book in advance during peak summer season (June–August)
  • Bring motion sickness tablets if you are prone to seasickness
  • Food is not included — eat before departure or bring your own snacks
  • Snorkelling equipment is provided, but you may bring your own mask for comfort
  • Children are welcome; inform the operator of any special requirements at booking
  • Arrive at the meeting point at least 15 minutes before departure

Traveler Reviews

Blue Cave Dubrovnik What Visitors Are Saying

See why travellers call this the best blue cave Dubrovnik experience on the Elaphiti Islands.

★★★★★

"Absolutely magical morning on the water — the glowing turquoise light inside the cave took our breath away. Our guide was knowledgeable, funny, and made sure everyone felt safe during the swim stop. Šunj Beach was a perfect way to wind down after the caves, with crystal-clear water and a relaxed vibe. Easily the highlight of our whole Dubrovnik holiday."

"We almost skipped this tour because we were short on time, and I'm so glad we didn't. The Green Cave was stunning, but the Blue Cave genuinely looks like something out of a dream when the light hits the water just right. The boat was comfortable and never felt overcrowded, and the crew handed out snorkelling gear for the beach stop. Book it — you won't regret it for a second."

★★★★☆

"Really enjoyed this trip overall and would definitely recommend it to anyone visiting the area. The caves themselves are spectacular and the captain knew exactly when to position the boat for the best lighting effect. I'm knocking one star off only because the beach stop felt slightly rushed on our particular departure, but that's a minor gripe. The scenery along the whole route is gorgeous."

★★★★★

"Our family of four — including two teenagers who are notoriously hard to impress — all agreed this was the best excursion of our entire trip. Swimming inside the cave felt surreal, and the guides were patient with the kids the whole time. Šunj Beach gave everyone a chance to relax and grab a cold drink before heading back. A truly unforgettable few hours on the Adriatic."

FAQ

Blue Cave Dubrovnik Frequently Asked Questions

Everything you need to know before you set sail on this island cave adventure from Dubrovnik.

The Blue and Green Caves Boat Tour from Dubrovnik with Šunj Beach includes a guided speedboat ride out to the Elaphiti Islands, entry visits to both the Blue Cave and the Green Cave, a swim and snorkel stop at Šunj Beach on Lopud Island, and all necessary safety equipment. Bottled water is provided on board, and a knowledgeable English-speaking guide accompanies every departure. Transfers from your Dubrovnik accommodation are not included by default, so plan to make your own way to the departure point.
The full experience runs approximately four to five hours from the moment you board until you return to the dock. Departures typically leave in the morning, which also gives you the best natural lighting conditions inside the caves — particularly important for the famous blue glow. Exact departure times can vary by season, so check your booking confirmation for the precise schedule. Arriving at the meeting point at least ten minutes early is recommended.
The cave itself is a natural sea grotto on Bisevo Island and is generally accessible from April through October when sea conditions are calmest. Outside peak summer season the tours still run, but rough Adriatic weather can occasionally force a last-minute change of route for safety reasons. If conditions prevent entry on the day of your trip, the crew will do their best to substitute an equally impressive alternative stop. Always check the weather forecast the evening before your departure.
You do not need to be an experienced swimmer to visit the caves themselves — you'll view the glowing interior from the boat. However, the Šunj Beach stop involves an open-water swim, so a basic comfort in the sea is helpful. Life jackets and snorkelling equipment are available on board for anyone who wants extra confidence in the water. Children are welcome, and the guides are attentive to all ability levels throughout the trip.
Pack a swimsuit and a light towel, as well as sunscreen with a high SPF since you'll be on the open water for several hours. Sunglasses, a hat, and a small waterproof bag for your phone and valuables are also strongly advised. Comfortable non-slip footwear is useful for boarding and disembarking the speedboat. There are small beach bars at Šunj if you'd like to buy snacks or extra drinks during the stop.
You can reserve your place directly through Viator, where the Blue and Green Caves Boat Tour from Dubrovnik with Šunj Beach is listed with instant confirmation. Most departures offer free cancellation up to 24 hours before the start time, giving you flexibility if your plans change. Payment is processed securely at the time of booking, and you'll receive a voucher to present at the meeting point. Group sizes are limited, so booking in advance — especially in July and August — is highly recommended.
