Snorkeling in Dubrovnik: Blue & Green Caves with Speedboat
Swim inside caves where light turns the water electric blue.
A morning speedboat tour from Dubrovnik to the Elafiti Islands combines snorkeling at the Blue Cave and three Green Caves with swimming time and a beach break on Sunj. The 8:30 AM start avoids the larger groups that arrive later. The tour includes snorkeling equipment, bottled water, and a free drink (beer, wine or water for adults 18+), with an English-speaking guide leading a small group through four hours of stops and water time.

The experience
The boat leaves Dubrovnik at 8:30 AM and heads straight to the Blue Cave on Kolocep Island, where you'll spend about 40 minutes swimming and snorkeling in water so clear the light refracts off the sand below and fills the cave with blue. The color is the draw. It's the kind of thing that stops people mid-stroke. After that, you move to three Green Caves on the same island, another 45 minutes in the water with snorkeling gear, where the sea shifts between blue and green depending on the angle and depth.
By mid-morning you're at Sunj beach on Lopud Island with an hour and 40 minutes to decompress. The beach has three restaurants in the trees if you want to eat. Most people float in the shallows or sit on the sand. The speedboat and the small-group format mean you're not herding with fifty other people. The early start is deliberate, timed to hit the caves before the afternoon tour boats arrive.
Snorkeling equipment is on board, so you don't pack it yourself. Water and a drink come with the ticket. The guide speaks English and stays with the group the whole way. The tour runs June through mid-September, and the morning timing matters: the caves are lit best early, and the water is calmest before the afternoon wind picks up.
Is this one for you?Book this tour if you want to snorkel the caves when light and water conditions are best: the 8:30 AM start and small-group size keep crowds minimal during peak season.

Top questions
Can children come?
Yes. Ticket types: Child (under 1).
What happens if it rains?
It may be canceled due to bad weather. If that happens, you're offered another date or a refund. Free cancellation up to 24 h before the start.
What's the Blue Cave actually like when you get there?
The Blue Cave sits on the south side of Kolocep Island and fills with blue light created by sunlight refracting off the sand and water below. You swim and snorkel inside it for about 40 minutes, which is long enough to circle around and see how the color shifts as you move.
How much time do you actually spend in the water versus on the boat?
You're in the water for roughly 85 minutes total (40 minutes at the Blue Cave and 45 minutes at the three Green Caves), then you have an hour and 40 minutes at Sunj beach. The boat moves between stops but doesn't dock for long stretches.
Do I need to be a strong swimmer to snorkel on this tour?
The tour is not recommended for non-swimmers. The caves and beaches are in open water, and while the snorkeling is not technically difficult, you need to be comfortable in the sea and able to manage a snorkel and fins.
What's included in the free drink, and who can have it?
Beer, white wine, and water are available on board at no extra cost. The drinks are for adults 18 and above only. Bottled water is available to everyone.
Why does the tour start at 8:30 AM instead of later?
The early start is designed to reach the Blue and Green Caves before the larger afternoon tour groups arrive, so you get more space in the water and better light inside the caves.
What should I bring that's not included?
Bring a towel and sunscreen. The tour provides snorkeling equipment, water and a drink, but you'll need sun protection and a way to dry off between the water stops.
