A wooden boat makes summer feel personal. This private trip from Medulin sends you to Kamenjak National Park for clear-water swims, then to Otok Ceja for a long beach break.

You get the Kamenjak area at your pace, not on a tick-tock group schedule, plus a welcome drink as you cruise the Medulin archipelago.

I especially like the hands-on crew-led swim stops, including the underwater cave experience near the southern tip of Istria. And I like that lunch and drinks come with the day, served onboard while you’re still in motion.

One consideration: the best moments happen in the water, so good weather matters, and some stops can feel short if you’re hoping to linger forever.

Key highlights worth planning for

• Private mini cruise means you can swim when you want, within the scheduled time blocks.
• Kamenjak National Park swim stops include admission, plus an underwater cave option with crew.
• Golumbera cave visit is set up for swimming into the underwater cave, or staying onboard for the view and fish feeding.
• Porer Lighthouse photo time adds a dramatic Austro-Hungarian landmark stop during the coastal drive-by.
• Ceja Island beach time is the long swim and snorkel break, with a bar, restaurant, and toilets.
• Onboard comfort includes restroom and WiFi, plus a lunch service and drinks lineup.

Medulin departure at Riva 18, and what you actually get onboard

This is a private boat experience based out of Medulin, starting at the Port authority Medulin, Riva 18. The vibe is simple: you meet, board the wooden boat, and get moving without the hassle of fitting into a larger group flow.

What I like right away is that the day is built around comfort during the cruise. There’s restroom onboard and WiFi onboard, so you’re not stuck in full tourist mode the whole time. You also get a welcome drink while you head out, and the crew runs the day with a friendly, service-forward style, with names like Ricardo, Ilia, Sandra, Tamara, Vitali, Artur, and others showing up across different trips.

One practical detail for your day plan: there is a shuttle option, but it is not included in the tour price. If you need it, plan on 7 euros per person round trip, and kids age 0 to 4 ride free for that shuttle.

Kamenjak National Park swim scenery, plus the southern tip of Istria

Your first big block of time is spent along the southern coast of Istria, moving from the Medulin archipelago zone toward the Kamenjak National Park area. You start with a panoramic view on the Medulin archipelago, then cruise along the coast near Premantura and into Kamenjak.

This stop is designed to give you both motion and a point of arrival. After about 45 minutes, you reach the most southern point of Istria by an underwater cave. Admission is included for this segment, so you’re not juggling extra tickets while you’re trying to enjoy the water.

Here’s how this helps you as a visitor. The Kamenjak coast is the kind of place where the views are good even when you are not in the water. The cruise sections connect the dramatic shoreline with the natural swim spots, and you get to see the coast in layers: open water, then close-in rock and cave country near the southern tip.

If you’re the kind of person who likes to take breaks between swims, you’ll also appreciate that this stop is not a single long swim. It’s paced, with time to look, settle, and then use the underwater-cave moment when it fits you.

Cave Golumbera stop: swim with the crew or stay on board

After the first Kamenjak experience, you shift to the cave-focused break at Cave Golumbera. This is built around a planned swim into an underwater cave, and the crew goes with you to make it work.

You’re scheduled for about 30 minutes here. The boat has options: you can swim into the cave with the crew, or you can stay onboard and just enjoy the view while the crew helps with fish feeding. Either way, you’re not stuck with only one activity.

This is also one of the moments the staff is most praised for. Names that came up repeatedly in happy notes include Anna, Monica, Ana, and Ilia, plus others like Diana and Maria. The consistent theme is clear communication and being willing to help people manage the steps of the experience.

A realistic note: 30 minutes can feel quick if you fall in love with the water and want one more pass in the cave. If you’re traveling with kids or anyone who needs a careful pace, that shorter window is still usually manageable, but you should go in expecting a taste, not a long session.

Porer Lighthouse photo ring, with Austro-Hungarian history in plain talk

Between the swim stops and the lunch segment, the route includes a drive-by around the Porer lighthouse. You get time to take pictures from the water, and the crew shares what matters about the lighthouse, both its history and its current use.

This stop matters more than it might sound in a short itinerary, because it gives you a mental reset. After time spent looking at caves and swimming, you get a clear, landmark view. Even from a boat, the lighthouse area provides a strong sense of place at the southern end of the peninsula.

If you like photography, aim to have your phone or camera ready before you reach the moment. The crew can help with the timing so you get usable angles, and it becomes a nice memory piece that complements the swim stops.

Lunch on board during the Kamenjak return, plus a drink line you will use

Lunch is served onboard while cruising along the Kamenjak coast. Your schedule includes a slow move back into a calm bay near the national park, and this section also includes about 45 minutes of time connected to the lunch flow. Admission for this part is marked as free, so again, you are not paying extra to enjoy the main area.

Food options are simple and flexible: grilled fish, grilled meat, or a vegetarian meal. Drinks are part of the package, which is one reason people call this good value. You get wine (white and red), water, juices, and a welcome drink, plus alcoholic beverages for people age 18 and older. In practice, that means you can keep hydrating and you can also enjoy a glass of wine without paying for each pour.

If you are traveling with kids, this onboard meal format is usually a relief. People mention that families found the experience smooth, with staff going the extra mile for practical needs like helping with a stroller. The boat setup helps here, because you are not moving between restaurants and viewpoints for hours.

A small caution that is worth taking seriously: you are still on the coast in summer, so come with your swim-ready mindset, but also protect yourself from sun. You will be out there long enough that sun protection should be on before the boat is, not after.

Ceja Island: long beach time with toilets, bar, and snorkel-friendly water

The biggest relaxation moment is the stop at Otok Ceja, often described as a true beach break. Your scheduled time is about 2 hours, with the plan sometimes stated as 2 to 3 hours depending on how the day runs.

This is where you slow down. You can swim, snorkel, sunbathe, and simply relax. The island has a bar and restaurant, plus toilets, so you are not stranded in a bare-bones setting.

If you care about water clarity, this is the stop that stands out the most in the positive notes. People highlight super clear water, and the kind of bright visibility that makes a snorkeling break feel worth it. It is also a good change from the cave experiences, because you get open-water time without the tight underwater cave limits.

The Ceja stop is also a chance to refill on energy. You can grab refreshments on the island, and you have a practical bathroom option right there. That makes it easier for families and for anyone who prefers not to keep returning to the boat for basic needs.

One drawback to keep in mind, based on how people talk about the timing: if you fall in love with the cliffs and caves, you might wish for more time at the cave or coastal cliff moments. Ceja tends to soften that complaint, since the island break is generous.

Returning to Medulin: wrap-up and how to set up your departure day

After Ceja Island, you cruise back to Medulin slowly and finish the excursion at the return to Medulin Harbour. The final stretch is short, around 20 minutes, so your day ends without another long travel segment.

Because the schedule is built around water time, your best move is to plan your rest of the day with flexibility. If you have dinner reservations that are strict, pick something with a comfortable buffer. When conditions are right, you will likely feel like the day runs smoothly from stop to stop, with prompt departures mentioned in positive notes. When conditions are less ideal, the most you can do is stay ready for adjustments.

Also, keep in mind this tour requires good weather. The provider notes that the experience depends on weather conditions, and if it cannot run due to poor weather you will be offered a different date or a full refund.

Price and value: what $1,628 buys you on a private 5-hour day

This private tour is priced at $1,628.02 per group, with a maximum of 1. That means it is not priced like a shared group boat. You are paying for exclusivity, not just transportation.

So where does the value come from?

• Included lunch (fish, meat, or vegetarian) served onboard
• Included drinks, including wine, juices, water, and a welcome drink
• Onboard amenities, like restroom and WiFi
• Admissions included for Kamenjak National Park segments and the cave experience, plus Ceja Island marked as included
• Crew-led swim support during the underwater cave moment
• Time on a private island beach at Otok Ceja, with toilets and a bar and restaurant available

If you were to add all of that up separately on your own, it would be more expensive than you want to think about. Even the shuttle is optional at 7 euros per person round trip, but the main experience includes a lot of the expensive parts of a coastal day, like guided cave swim time and onboard meal service.

Who should book it? This is a strong fit for couples and small family groups who want water time without a big-group shuffle. People also mention the experience works well with children, especially because the crew is attentive and the boat setup is practical.

Should you book Sandra Boat Medulin to Kamenjak and Ceja?

Yes, if your idea of a great day is water first, views second, and food plus drinks included without extra stops. I’d book it if you want private pacing, are excited about Kamenjak swim time, and plan to spend real time on Otok Ceja.

I would hesitate if you dislike swimming or you do not want weather risk. The tour runs only when conditions are acceptable, and the moments that get the strongest praise involve getting into the water.

If you’re the kind of person who likes clear instructions and a crew that helps you make the most of each stop, this one is worth your attention. With staff members like Ilia, Vitali, Ricardo, Tamara, and others showing up again and again in positive comments, you’re not just buying boat time. You’re buying a guided, comfortable day that hits the best parts of the southern Istria coast.
