Blue & Green Cave,Sunj beach Small Group Tour with Speedboat

Kolocep’s Blue Cave is the star here: you swim straight into a dark opening where the sea takes on an otherworldly blue glow. I like the freedom of choosing a morning or afternoon departure, and I like that the day mixes active water time with a long, lazy stop at Sunj Beach. The speedboat ride adds some zip without turning the whole outing into a race.

The catch is simple: this is a water-first tour, and the sea can feel cold, especially outside midsummer. You need to be comfortable swimming, and the meeting point at Lapadska obala 4 can take a little finding. Arrive early, bring a towel and sunscreen, and do not count on this being a quiet private charter, since the boat may carry up to 50 people.

Key points to know before booking

• Swim into Kolocep’s Blue Cave: You get about 40 minutes for swimming at the cave, with clear water and the chance to enter the cave itself.
• Snorkel around the Three Caves: A second Kolocep stop gives you about 45 minutes to explore by mask and snorkel.
• Spend nearly two hours at Sunj Beach: The sandy beach is made for a slower finish, with three restaurants for food and drinks.
• Choose your pace: Swim, snorkel, float on a pool noodle, or stay on the boat with a drink.
• Beat the crowds with an early start: Morning departures have the best chance of reaching the caves before queues of boats build.
• Pay $78.60 for a full half-day: The price includes the speedboat, captain, drinks, water, and snorkeling equipment, but not towels, sunscreen, food, or beach drinks.

Why the Blue Cave is the main event

The trip starts from Dubrovnik and heads toward Kolocep Island, one of the Elafiti Islands. The speedboat gets you there quickly and makes the ride part of the fun. You are out in the open water, with the coast slipping behind you, rather than sitting on a slow sightseeing boat for most of the morning.

At Kolocep, the first stop lasts about 40 minutes. This is the best time to get in the water, swim toward the cave opening, and see how the light changes inside. The effect depends on the sun and sea conditions, but the cave is most impressive from the water, not from a seat on the boat.

You may want to take your time here. Several captains, including Toni, Matj, Mate, and Luka, have been praised for allowing people to swim at their own pace while keeping a close eye on the group. Pool noodles are available on some boats, which is useful if you want to float rather than work constantly at swimming.

The water can be cold. One guest called it a drawback, while others found it refreshing even in October. That is a fair warning. You should not assume that a sunny day means warm water, and the tour is specifically not recommended for non-swimmers.

The Blue Cave stop can feel very different depending on departure time. An early morning trip may arrive when only a few boats are present. Later in the day, the same area can become crowded, with boats waiting for access. If the cave is your main reason for booking, choose the morning option if available.

Snorkeling around Kolocep’s Three Caves

After the Blue Cave, the boat moves to the Three Caves, also on Kolocep. You get roughly 45 minutes here, and this stop is less about the blue glow and more about looking beneath the surface.

Snorkeling gear is included, so you do not need to pack your own mask and fins unless you prefer using familiar equipment. The water is clear enough for a pleasant look below the surface, and the rocky cave setting gives the stop a sense of discovery without requiring a long hike or difficult climb.

I like this part of the trip because it gives the morning a second act. The Blue Cave is about the light and the setting. The Three Caves are about swimming around, spotting what the water reveals, and using the time more freely.

The captain may come into a cave with you, depending on the conditions and the group. That can help if you are unsure where to go or how to approach the openings. It is also worth listening closely to instructions before entering. Boats, rocks, swimmers, and changing water conditions do not mix well when people rush.

You can choose how active to be. Strong swimmers may spend most of the time in the water. Others may use a noodle, snorkel near the boat, or simply enjoy a drink and the view. The tour works best when you accept that not every person in the group will want the same pace.

Sunj Beach gives the tour a slower finish

After the caves, you head to Sunj Beach for about one hour and 40 minutes. This is not a quick photo stop. It is the part of the day where you can dry off, swim again, sit in the sand, or have lunch.

Sunj has three restaurants, so you can buy food or a drink during the free time. Beach facilities are not included in the tour price, and some seating areas may expect you to make a purchase if you want to use shaded lounge chairs. That is worth knowing before you arrive, especially if you are traveling with children or planning to spend the whole break out of the sun.

The beach is a useful counterweight to the caves. Four hours of constant swimming would be tiring, but nearly two hours at Sunj lets you choose your own rhythm. I would use the first part of the stop for lunch and the rest for a final swim, provided the water and weather suit you.

The beach can also become busy. An early boat has a better chance of reaching the sand before the biggest flow of day visitors. Several people found the beach peaceful when they arrived early, while later arrivals saw more boats and more activity. That makes the departure choice important for both cave access and beach comfort.

What the speedboat adds to the experience

The speedboat is not just transport between stops. It lets you cover Kolocep and Sunj in a short half-day, leaving time for real swimming at each place. A slower boat could make the same route feel like a long ride with brief stops.

The ride can be lively when the sea is calm. On a windy or choppy day, it may feel bumpy, and the captain has to adjust speed and route. One captain was praised for handling rougher conditions carefully, which is exactly what you want on a small boat.

Boat comfort depends on the vessel and group size. The experience can feel intimate with six or seven people, and some departures have had only a small handful of passengers. But the stated maximum is 50, so you should not book expecting a guaranteed tiny group.

That range matters. A small group gives you more space, easier conversation with the captain, and less waiting to get into the water. A larger group may still enjoy the same stops, but boarding, swimming instructions, and access to the best spots can feel less personal.

The captains are a major part of the day. Toni is repeatedly singled out for his humor, local information, safe handling, and willingness to join people at the caves. Luka has been praised for making the ride conversational and offering useful advice about food and the area. Matj and Mate also receive strong marks for friendly, attentive service.

The names may not be guaranteed when you book, so think of them as examples of the company’s guiding style rather than a promise. Your captain will shape the day, particularly when weather, crowds, or group preferences require small changes.

What is included, and what you still need to pack

The $78.60 price includes the speedboat trip, captain, bottled water, snorkeling equipment, and alcoholic drinks such as beer and white wine. Soda is also described as an available drink option. The captain may offer drinks during the ride, which is a welcome touch after swimming.

You should bring:

• A towel
• Sunscreen
• Swimwear
• Dry clothes for the ride home
• A payment card or cash for lunch and beach drinks

Towels and sunscreen are not included. Food at Sunj is also extra, as are drinks purchased at the restaurants. The included beer and wine are a bonus, but they do not replace lunch, so budget for a meal if you plan to stay at the beach for the full break.

The price is good value if you want several things in one outing: a fast boat, two cave areas, swimming, snorkeling equipment, drinks, and substantial beach time. It is less compelling if you only want a short scenic boat ride or prefer to spend the day on land.

You are also paying for convenience. Reaching these stops independently would require arranging your own boat transport and equipment. The tour gathers the main water highlights into four hours, which is especially useful if you have limited time in Dubrovnik.

Timing matters more than you might expect

You can choose a morning or afternoon tour. That flexibility helps if you are arriving from a cruise ship, have other plans in Dubrovnik, or simply do not want an early start.

Still, I would choose the morning departure if cave swimming is your priority. Early boats have reached the Blue Cave before the crowd, while later arrivals have seen more than ten boats waiting in the same area. The difference can change the feel from quiet and magical to busy and tightly scheduled.

Cruise ship passengers can walk from the port area to the meeting point in about 20 minutes, according to the route described by past participants. That makes this a practical shore activity, but allow extra time because the meeting point can be confusing to find.

The start point is Lapadska obala 4 in Dubrovnik, and the tour ends back there. Confirmation is provided at booking, and the location is near public transport. Since one person missed the meeting after struggling to locate the dock, I would not cut the timing close. Find the dock in advance if possible, and keep the local meeting time in mind.

The tour lasts about four hours. That includes the ride, roughly 40 minutes at the Blue Cave, about 45 minutes at the Three Caves, and around one hour and 40 minutes at Sunj. Small changes can happen because of weather, sea conditions, or crowd levels.

Who will enjoy this tour most

This is a strong match for you if you want a short, active sea outing rather than a full-day cruise. Couples, families with confident swimmers, and friends who enjoy mixing water sports with beach time should find the format easy to like.

It is also a good choice if you want your captain to handle the practical details. The boat, route, snorkeling equipment, and drinks are arranged for you, leaving you to focus on the water and scenery.

Families should note that the tour is not suitable for non-swimmers. Children who are comfortable in the sea may enjoy the caves and pool noodles, but the experience is not a dry sightseeing trip with occasional views. Everyone needs to be prepared for swimming from the boat and for cold water.

You may want to choose another activity if you dislike small boats, get uncomfortable in choppy conditions, or need guaranteed shade and dry seating. The tour is built around outdoor water time, so poor weather can change or cancel the outing.

Free cancellation is available up to 24 hours before the start time. If bad weather forces cancellation, you are offered another date or a full refund. Changes made within 24 hours are not accepted, so check the forecast early.

Is the $78.60 price worth it?

For four hours, the price is reasonable. You receive transportation to several hard-to-reach spots, swimming time at two cave areas, snorkeling equipment, bottled water, beer or wine, and nearly two hours at a beach with restaurants.

The value is strongest when you use the whole package. Swim at both cave stops, take advantage of the gear, enjoy the boat ride, and allow enough time at Sunj for lunch and another dip. If you only stay on the boat and skip the water, you lose much of what makes the outing worthwhile.

A private boat would give you more control, but this experience is designed to keep the cost lower by sharing the ride. Ask yourself what matters more: a fixed route at a reasonable price, or complete control over stops and timing.

Should you book the Kolocep and Sunj tour?

I would book this if you are a confident swimmer looking for Dubrovnik’s best combination of caves, clear water, speedboat travel, and beach time in one manageable outing. The Blue Cave, the flexible pace, and the long stop at Sunj give the trip a satisfying shape.

Choose the morning departure when possible, arrive early at Lapadska obala 4, and bring your own towel and sunscreen. If cold water or crowded cave stops would spoil the day for you, skip it. For everyone else, this is a lively, practical way to get out of Dubrovnik and onto the Elafiti Islands without spending a full day on a boat.
