Boat Tour to Mljet National Park & 3 Islands

The best part of this day is the variety. You get Odysseus Cave, two blue-cave swims, quiet island villages, and three hours to explore Mljet National Park, all without arranging several ferries. I like the small group size and the lively RIB boat, which covers a lot of coast quickly. I also like that the crew supplies snorkel gear, bottled water, life jackets, and wind jackets.

The trade-off is the boat itself. Most seats are long raised benches that you straddle, and a fast ride over choppy water can be hard on your back or hips. This is an active day, not a gentle sightseeing cruise, and the €25 Mljet National Park entrance fee is extra.

Key things to know before you book

• Odysseus Cave is the main swimming adventure: You enter from the sea, with snorkeling gear supplied, and need to swim underwater through part of the cave.
• Mljet gets three hours: You can walk, bike, kayak, swim, or take the small ferry across the lakes, but you will need to choose how to use your time.
• The RIB boat moves fast: The speed lets you reach several islands in one day, but the ride can feel bouncy and exposed.
• The group is capped at 12 people: That makes the day more personal than a large excursion boat.
• Pack for sun and spray: Bring sunscreen, a towel, water shoes, walking shoes, a waterproof phone case, and a light jacket.
• Weather can change the plan: The blue cave or another island may be replaced if sea conditions make the original route unsuitable.

Why this boat trip covers so much coast

At $163.33 per person, this is not a cheap beach transfer. It is a full-day outing of about 10 hours, with fuel, water, safety equipment, snorkel gear, and wind jackets included. The value comes from the distance covered and the number of places you can reach in one day.

Doing this route independently would mean coordinating ferries, island transport, park admission, and return times. That can work if you have several days, but it is difficult to combine Lopud, Mljet, Odysseus Cave, Šipan, and Koločep in one day without a boat.

The National Park entrance fee is not included. It costs €25 per person, so add that to the advertised price. You should also carry cash for drinks, food, rentals, and tips. Some visitors bring a picnic so they do not lose park time searching for lunch.

The boat holds no more than 12 people, which matters on a long day. You are not lost in a crowd, and the guides can help with swimming, equipment, and plans inside the park. The guides vary by departure, but Marko, Ante, George, Suzie, Toni, and Carlo are among the crew members named for this route. The strongest praise goes to the crew’s friendly attitude, safety focus, music, and willingness to adjust the day to the sea.

Lopud gives you a gentle start

The boat leaves from Lapadska obala 4 in Dubrovnik at 7:30 a.m. An early start helps the day work, since you have several islands and long stretches of water ahead.

Lopud is the first stop, with about 40 minutes to look around. The old port offers a pleasant first walk, and you can see the waterfront, the Franciscan Monastery, and the botanical garden. The island is also known for tall palm trees, including some described as among the highest in Europe.

This is not enough time for a long walk across the island. Think of Lopud as a brief introduction to the island villages rather than a full visit. You can stretch your legs, take photos, and see the Benedictine church and its view before returning to the boat.

Saplunara and the short beach stop

The listed route includes a very short stop at Blace Beach near Saplunara on Mljet, about five minutes. That is enough for a quick look and a few facts from the guide, but not enough for a proper beach session.

The stop matters less for sightseeing than for breaking up the boat ride before the main swimming sites. If you are expecting a long stay at every beach, adjust those expectations. The day is built around several short experiences, with the longest free time reserved for Mljet National Park and Šipanska Luka.

Swimming into Odysseus Cave

Odysseus Cave is the day’s most memorable water stop. The cave sits on the southern side of Mljet, and the boat stops offshore so you can swim toward the opening.

You need to pass underwater through part of the entrance, so this stop suits confident swimmers. Snorkel gear is supplied, and the water changes through several shades of blue. You can look for marine life around the rocks, then climb or walk along the nearby cliffs for views from above.

Bring water shoes. The rocks inside and around the cave can be sharp. A towel is just as useful, since you will be wet before getting back onto the boat. A waterproof phone case is a smart addition if you want photos without risking your phone.

The cave is not a passive viewpoint. You need to swim, handle rocky footing, and feel comfortable in open water. Conditions can also affect how much time you spend there. One family had a child stung by a jellyfish, so keep an eye on the water and follow the crew’s advice.

Three hours in Mljet National Park

Mljet National Park is the heart of the day. The park covers pine forest and two connected saltwater lakes, Malo Jezero and Veliko Jezero. You arrive near Pomena, then continue into the park for roughly three hours.

The park gives you choices:

• Walk the mostly flat paths around the lakes.
• Rent bikes or e-bikes and cover more ground.
• Hire a kayak.
• Swim from the shore.
• Take the small ferry toward the island church in the middle of the lake.

Three hours is useful, but it is not enough for everything. If you rent bikes, you can cover a good section of the larger lake and see more of the park. If you choose the ferry and the island church, you may not have time for a complete bike ride. A short swim across to the small island may be possible from the bike path, but you should only do that if the conditions and your swimming ability make it sensible.

I would decide your plan before you arrive. The park is the place where you can easily lose time, especially if you stop for lunch. A picnic lets you use more of the three-hour window for cycling, walking, or swimming. The paths are generally flat, though some access points include stairs.

This stop also provides the calmest contrast to the fast boat. After hours of spray, wind, and engine noise, Mljet offers pine trees, quiet water, and room to set your own pace. If you prefer nature to beach bars, this is likely to be your favorite part of the day.

Šipanska Luka brings village time

The next major stop is Šipanska Luka on Šipan, part of the Elafiti Archipelago. You have about two hours here, which gives you time for a beach break, a drink, a meal, or a walk past historic buildings.

This is a useful change of pace. You are no longer rushing from one swim to the next, and you can choose how active you want to be. A small bar and beach make it easy to relax, while the village and its historic monuments give you something to see on foot.

The exact island plan can change. On one departure, the crew chose Šipan instead of Koločep because the sea conditions made it the better choice. That flexibility is a benefit when it is handled well, but it means you should not treat every listed stop as guaranteed.

Koločep’s Blue Cave and the final swim

The planned final island stop is Koločep, where the Blue Cave provides another short swimming adventure. Inside, blue water sits below a dark rock ceiling, creating a dramatic effect without a long hike or complicated access.

The area also works for snorkeling and cliff jumping. You should only jump if the crew confirms the depth and conditions, and you should be comfortable getting back into the boat. The cave may be unavailable if the weather or sea state turns poor, so keep your expectations flexible.

This is one of the trip’s most photogenic moments, but it is also another active stop. You will get wet, climb over rocks, and spend much of the day outside. If you want shade, the boat may have a bimini sun cover, but conditions and equipment can vary. Bring a hat and plenty of sunscreen rather than relying on the canopy.

What the RIB ride feels like

The boat is a rigid inflatable boat, similar to a Zodiac, rather than a large ferry or a cushioned sightseeing cruiser. Its size and speed are the reason this route can include so many islands.

You get wide views in every direction, and the open design makes the ride exciting. The crew often plays music, which adds a relaxed holiday mood. Wind jackets are valuable early in the morning and whenever the boat is moving, even on a warm day.

The seating deserves careful thought. The back seats are more like ordinary boat seats, while many other positions use long benches that require you to straddle them. Sitting side-saddle can give your hips a break, but you are still on the boat for several hours.

Anyone with a bad back, hip trouble, or other physical concerns should contact Sea Breeze before booking. The activity calls for moderate fitness and is not recommended for people older than 65. That age guidance is broad, so your own mobility and comfort on a bouncy boat matter more than the number alone.

One poor experience raised concerns about a damaged bimini fitting during a rougher outing. Sea conditions and equipment can change, and the operator responded that the failure came from a concealed part. Most of the available feedback describes a safe and well-run day, but it is fair to ask about current boat condition if shade and seating are important to you.

What to bring for a better day

Pack lightly, but bring the right things. There is room for about one bag per person, either beside you or on your lap.

Bring:

• A towel
• Water shoes
• Walking shoes
• Swimsuit worn under your clothes
• Sunscreen and a hat
• A light jacket
• Waterproof phone protection
• Cash for the park, food, drinks, rentals, and tips
• Snacks or a picnic lunch

Bottled water is supplied, and the boat carries safety equipment including life jackets and insurance. Snorkel gear is also included. You still need your own towel and sun protection.

The boat can be wet, especially when moving quickly. Keep electronics and spare clothing protected. Windbreakers are supplied, but you may still want a dry layer for the return ride.

Who will enjoy this day most

I would choose this trip if you want to see a broad section of the Dubrovnik coast in one day and enjoy active stops. It suits couples, families with older children, and solo visitors who like small groups, swimming, and a fast pace. The six and eight-year-old children described in one outing managed the day well, but every child’s swimming ability and comfort on a speedboat are different.

This is less suitable if you want long, quiet beach time or a padded cruise. It is also a poor match for anyone with significant back or hip pain, anyone uncomfortable swimming into a cave, or anyone who needs reliable shade for the full day.

The route is not fully fixed. Sea conditions can remove the Blue Cave or shift the final island to Šipan. If bad weather cancels the trip, you can choose another date or receive a full refund. You can also cancel for a full refund up to 24 hours before the 7:30 a.m. start time.

Should you book the Mljet and three islands tour?

Book it if you want one busy, scenic day that combines fast boat travel with swimming, caves, beaches, and a proper block of time in Mljet National Park. The price is reasonable for the distance covered and the small group, but remember to add the €25 park fee and your food or rental costs.

Skip it if your body does not handle hard boat seats, if you prefer a slow ferry, or if your ideal day means staying in one village. For most active visitors, the strongest plan is simple: wear your swimsuit, bring water shoes and a towel, take a picnic, and save your energy for Mljet and Odysseus Cave.
