Blue Cave, Green Cave & Lopud Beach small group Speed boat Tour

The best part of this Dubrovnik boat trip is that you swim into the caves, rather than simply taking photos from a boat. Sunlight turns the Blue Cave’s water electric blue, while the Green Caves glow emerald when the light hits at the right angle.

I like the small maximum group of 18 and the useful extras: masks, snorkels, pool noodles, water, soft drinks, beer, wine, and grappa. I also like the simple half-day timing, which leaves room for Dubrovnik’s old town. The main catch is the sea. Rough water can make the speedboat ride uncomfortable and may force the skipper to change the route.

Key points to know before booking

• Swim to the Blue Cave: The boat anchors about 20 meters away because the entrance is too narrow for the speedboat.
• Four hours on the water: The trip combines several cave stops with about an hour at sandy Šunj Beach.
• Drinks are included: Expect bottled water, soft drinks, juices, local beer, red and white wine, and grappa.
• Guides shape the experience: Captains such as Ivan, Marco, Luca, Leo, Mario, and Dora have been praised for friendly service and careful handling of the boat.
• Crowds can affect the caves: The Blue Cave and some green caves may be busy, especially in good weather.
• Weather matters: Strong wind and choppy seas can shorten, move, or replace cave stops.

Why this four-hour boat trip works well in Dubrovnik

Dubrovnik is famous for its stone walls, polished streets, and busy summer lanes. The sea offers a welcome change of pace. From the speedboat, you see the city from a different angle, with the old walls rising above the water and Lovrijenac fortress perched on its steep 37-meter cliff.

The opening ride is not just transport. Your skipper points out the old town and shares local legends and facts as the boat passes below Lovrijenac. That short introduction gives the trip some place and character before the swimming begins.

At $84.65 per person, this is not the cheapest way to reach the coast. Still, the price covers a boat ride, several swimming sites, snorkeling equipment, drinks, and a beach stop. You are paying for a compact outing that combines several activities without spending a full day away from Dubrovnik.

The value is strongest if you want an active half-day and do not want to arrange boat hire, equipment, and transport on your own. It is weaker if you mainly want a long, quiet stay at one beach or expect a guided cave tour on foot.

The Blue Cave requires a swim

The Blue Cave is the star of the trip. Natural light enters through the cave opening and reflects through the water, creating the blue glow that gives the place its name. The effect depends on daylight, water conditions, and the position of the sun, so it may look stronger at one time of day than another.

The speedboat cannot enter. It anchors around 20 meters from the opening, and you swim the rest of the way. The entrance is small, and you need to pass through the water to see the interior. This is important: the cave is not a boat-access attraction where you sit aboard and look inside.

Masks and breathing tubes are supplied, and pool noodles are available if you want extra support. The stop lasts about 40 minutes, although actual time in the water can vary with conditions and crowding.

You should be comfortable getting into open water and swimming around a rocky entrance. The cave visit can be thrilling, but it is not ideal for anyone who expected a dry sightseeing stop. One particularly useful point is that the guides remain on the boat for the cave visits, so you have some freedom to explore, but less formal guidance once you leave the boat.

The Blue Cave can also become crowded. Several boats may arrive at once, and the narrow entrance creates a bottleneck. Go with modest expectations: the color is the attraction, not a long subterranean expedition.

Green Caves, Dark Cave, and Passage Cave

The next section focuses on the green caves and other rocky openings along the coast. Sunlight creates an emerald cast in two of the caves, giving them a different mood from the intense blue of the first stop.

The Canyon Cave is a natural passage cut through the rock. Depending on the sea and the group, you may swim and snorkel through the opening. The advertised experience also includes the Dark Cave and Passage Cave, although the exact order and time at each spot can change.

Some passages are narrow and may involve swimming under a low rock shelf to reach another opening. This can feel like a small adventure rather than a passive boat excursion. It also means you should pay close attention to the skipper’s instructions before entering.

Conditions make a real difference here. On calm days, the water can be clear and inviting. On windy days, the same rocky entrance may feel awkward or unsafe. One green cave may be changed if another site is crowded, and rough seas can prevent swimming altogether.

That flexibility is sensible from a safety point of view, but it can disappoint if you have booked the trip for one exact cave. Ask the crew what is possible that day, especially if the sea looks rough at departure.

Šunj Beach gives the trip a slower finish

After the cave stops, the boat heads to Šunj Beach on the south side of Lopud Island. You get about an hour here, giving you time to swim, sunbathe, or sit at the waterfront.

Šunj is known for pale sand and shallow water extending roughly 100 meters from shore. That makes it a useful stop for families and for people who are less confident swimmers. It is also a pleasant contrast to the rocky cave entrances, where you spend more time climbing in and out of the water.

The beach is not completely built around organized activities. There is a small bar, and you may find food, drinks, ice cream, and souvenirs nearby. Beach chairs cost extra, and towels are not included, so bring your own towel if you want to lie on the sand.

Allow some room in your expectations. The beach may be crowded and cleanliness can vary. One hour is enough for a swim and a break, but it is not a full beach day. If you want two or three hours on Lopud, this tour will feel too rushed.

The timing also varies in practice. Some departures have offered close to two hours at the beach when the cave stops were shorter, while others keep more closely to the planned schedule. Either way, Šunj is best understood as the relaxing last stop, not the main purpose of the outing.

What the speedboat ride feels like

The boat gives you a quick way to cover the coast, and the ride itself is part of the fun. You get broad views of Dubrovnik, the islands, and the open Adriatic. A covered section provides some shade, while seating at the front may offer a more exposed ride.

Speedboats are sensitive to wind and swell. In calm conditions, the fast ride feels lively and efficient. In rough weather, the same boat can hit the water hard. Several departures have been described as very choppy, with children and adults finding the ride uncomfortable.

This is the main practical risk of the excursion. A responsible skipper may slow down, change the route, substitute a swimming site, or return early if conditions are poor. That can mean missing the caves or reaching an alternative beach instead.

If the sea forecast looks poor, confirm the operator’s plan before setting out. The activity requires good weather, and a cancellation because of weather should result in either another date or a full refund. If the tour operates but the route changes, the experience may not match what you had hoped to see.

Drinks, equipment, and what you should bring

The included supplies add real value. You get snorkeling masks and breathing tubes, plus pool noodles for floating. Drinks include bottled water, sparkling drinks, natural juices, local beer, red and white wine, and grappa.

The selection is useful rather than luxurious. Beer is the main alcoholic option mentioned in the practical feedback, so do not assume a full bar. Drink service varies by skipper, but captains such as Mario and Ivan have been praised for keeping people supplied during the trip.

Bring a beach towel, since towels are not supplied. You should also bring swimwear, sun protection, and a dry change of clothes, although those last items are sensible suggestions rather than included equipment.

A phone or camera can be useful, but protect it carefully around the cave entrances. The combination of swimming, rocks, and a moving boat makes handling valuables awkward.

The skipper can make or break the outing

The trip is small enough that your skipper has a noticeable effect on the day. Captains named in feedback include Ivan, Marco, Luca, Leo, Mario, Dora, and Tony. Ivan is often described as friendly and attentive, while Marco is praised for humor and careful handling. Luca, Leo, Dora, and Mario have also been singled out for good service and a pleasant manner.

Expect basic commentary about Dubrovnik, the coast, and the caves rather than a long formal lecture. You will get practical advice on entering and leaving the water, but cave exploration is largely self-guided once you swim away from the boat.

Music may be played during the ride. One departure included loud dance music, which some people enjoyed and others found less appealing. The mood can be lively, especially on a sunny afternoon, but this is not a silent nature cruise.

The maximum group size is 18, though some departures may be smaller. A group of six, for example, feels far more personal and leaves more room around the boat. Even with 18 people, it is still a more focused experience than a large excursion vessel.

Who should book this Dubrovnik cave tour

This trip suits you if you:

• Want to swim and snorkel rather than only view the coast
• Have about four hours available
• Like a fast boat ride and several short stops
• Want drinks and equipment included
• Prefer a small group to a large day cruise
• Are happy to trade a long beach stay for several different sites

It is less suitable if you:

• Do not swim confidently in open water
• Need a fully guided cave visit
• Want guaranteed access to every named cave
• Get motion sick in rough water
• Prefer a quiet boat with no music
• Want a long, unhurried afternoon at Šunj Beach

The shallow water at Šunj helps families, but the cave stops are a different matter. Parents should consider whether children can handle swimming to a narrow entrance and returning to the boat. Service animals are allowed, and most people can participate, but the activity still depends on getting in and out of the water.

The tour is offered in English, with a choice of morning or afternoon departure. Morning light may suit the caves, while an afternoon trip can work better if you want a slower start. The exact light inside the Blue Cave depends on the day and conditions.

Booking value and cancellation terms

The average advance booking period is about 20 days, so reserve ahead if your Dubrovnik dates are fixed. The tour has a 4.9 rating from 2,572 ratings and is recommended by 98 percent of customers, which points to a consistently strong experience, though the rough-weather problems deserve attention.

You can cancel for a full refund up to 24 hours before the start time. Changes made inside that 24-hour window are not accepted, and late cancellations are not refunded. The operator may also cancel if the weather is poor or if the minimum number of participants is not reached. In either case, you should be offered another date, another experience, or a full refund.

Should you book the Blue Cave and Šunj trip?

Book it if you want an active, neatly packaged half-day on the water and you understand that the caves require swimming. The Blue Cave, emerald passages, coastal views, drinks, and sandy beach make a good mix for the price.

Skip it if you need a guaranteed itinerary, dislike rough speedboat rides, or want to spend most of the day on a beach. Before you board, ask about sea conditions, the expected time at Šunj, and which caves are safe to enter that day. With those expectations in place, this is a strong choice for seeing more of Dubrovnik’s coast without giving up your entire day.
