Snorkeling in Dubrovnik: Blue & Green Caves with Šunj Beach

Two caves, a sandy beach, and four hours on the clearest water near Dubrovnik

A small-group snorkeling tour from Dubrovnik visits the Blue Cave and Green Caves in the Elafiti Islands, then anchors at Šunj Beach on Lopud for swimming and time to rest. The speedboat holds a maximum of 12 people, includes snorkel equipment and life jackets, and departs at 8:30 a.m. from June through mid-September to avoid the crowds that gather at the caves later in the day. A professional guide speaks English, and beer and wine are included for adults.

The experience

You board a speedboat at Dubrovnik Port and head straight to Kolocep Island, where the Blue Cave and Green Caves sit on the south side. The Blue Cave's color comes from light bouncing off the sand and water below. The effect is immediate and unmissable. You spend about 30 to 35 minutes at each cave location, with time to jump from the rocks, snorkel in the passages, and move between them on the boat. The Green Caves have underwater passages you can explore with your snorkel gear. The Blue Cave is shallower and more about the color itself.

The second stop is Šunj Beach on Lopud Island, the largest sandy beach in the Dubrovnik area. You get roughly an hour and a half here: long enough to swim in the lagoon, which shifts from green to blue as it deepens, and to sit at one of the beach bars or the small forest restaurant up the hill. The water is warm and extremely clear. After the caves, this is the part of the day where you can actually rest instead of moving between stops.

Snorkel equipment and life jackets are provided. The boat carries no more than 12 people, which is why the 8:30 a.m. start matters: the caves draw crowds by mid-morning, and an early departure means you see them at their quietest. Beer and white wine come with the tour for adults 18 and over. The whole outing runs four hours from start to finish.

Is this one for you?The four-hour timeframe leaves your morning or afternoon free, depending on which half of the day you choose: early departure means you are back by lunchtime and the caves stay uncrowded. The boat holds only 12 people maximum, so you are not competing with a large group for space in the water or at the caves.

Top questions

Can children come?

Yes. Ticket types: Child (1 to 17 years).

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 exactly is the Blue Cave and why does it look that color?

The Blue Cave sits on the south side of Kolocep Island and gets its intense blue color from sunlight refracting off the sand on the bottom and bouncing back through the water. You see it best from inside the cave looking out, and the effect is created entirely by the light and the shallow sandy floor below.

Can I snorkel at both the Blue Cave and the Green Caves?

Yes. The Green Caves have underwater passages where you can snorkel and explore. The Blue Cave is shallower and better for seeing the color effect, but you can snorkel there too. You spend about 30 to 35 minutes at each location.

How much time do I actually get to swim and relax at Šunj Beach?

You have roughly an hour and a half at Šunj Beach on Lopud Island. That is long enough to swim in the lagoon, float, and sit at one of the beach bars or the forest restaurant without feeling rushed.

Is snorkel gear included, or do I need to bring my own?

Snorkel equipment is included in the tour. Life jackets are also provided for both children and adults.

Why does the tour leave so early in the morning?
