Medulin: Glass Boat Tour Experience to Kamenjak
The best part of this Medulin boat trip is the 45-minute stop at Kamenjak National Park, where you can swim from the boat, look into Golumber cave, and watch fish gather near the vessel. The glass-bottom design adds interest as you travel over the water, while the captain and crew handle the route.
I like the family-friendly pace and the simple comforts onboard: drinks, music, a toilet, and helpful crew. I also like that the tour combines several sights, including the Medulin archipelago, Kamenjak, and Porer lighthouse, in about three hours. The main caution is that the cave visit and lighthouse viewing may be briefer than the description suggests.
Key points to know before booking

- Kamenjak swimming stop: You get about 45 minutes for swimming, jumping from the boat, and exploring around Golumber cave.
- Glass boat sightseeing: The design gives you a chance to watch the water and local fish as you cruise.
- Family-friendly setup: Children receive attention from the crew, and drinks, music, and a toilet are included.
- Three-hour coastal outing: The route covers Medulin’s island group, Kamenjak National Park, and Porer lighthouse.
- Small group size: The boat accepts a maximum of 25 people, which keeps the trip more manageable than a large cruise.
- Important expectation: Food is not included, and some scheduled sights may receive only a quick look.
A short boat trip with a proper swim stop
This excursion works best as a compact taste of the coast rather than a full day at sea. You leave Medulin at 10:00 a.m., spend roughly three hours on the water, and return to the same meeting point. That makes it easy to fit into a wider Pula or Medulin schedule.
I like the balance here. You are not confined to a sightseeing boat for the entire trip, because the stop at Kamenjak gives you time to get into the water. At the same time, you do not need to organize a separate visit to the nature park or arrange your own boat hire.
The group limit of 25 people is useful. It is still a shared excursion, but it should feel more controlled than a large party boat with dozens of passengers. The captain and crew take care of navigation and the timing, so you can focus on the coast and the swim.
The tour is offered in English. Confirmation arrives when you book, and the meeting point is Tajana & Zlatni Rat Excursions Medulin, on Medulin Riva, postal code 52203. The boat returns there at the end.

Seeing Medulin’s archipelago from the water

The first part of the trip is about the view rather than one single attraction. Medulin’s archipelago opens up around you as the boat moves away from the harbor, giving you a broader sense of the small islands and coastal water than you get from shore.
The glass boat format matters most during this cruising section. You can keep an eye below the surface and watch for fish, especially when the boat slows or stops. The crew also offers drinks, and music keeps the ride from feeling too quiet or formal.
You should treat the sightseeing as a relaxed coastal survey, not a detailed guided tour of every island. The supplied information does not promise long stops at individual islands, and the full outing lasts only about three hours. If you want a slow, stop-heavy boat day, you may find this schedule too brisk.
Still, the route gives you variety. You see the archipelago, get a look at Porer lighthouse, and spend time at Kamenjak. For the price of $36.20 per person, that combination can be good value if your main goal is a pleasant half-day on the water with a proper swim break.
Kamenjak National Park and the 45-minute water stop

Kamenjak National Park is the heart of the outing. The boat stops for about 45 minutes, and this is when you can swim, jump from the boat, and spend time around the cliffs. If you prefer staying dry, you can remain onboard and watch the fish near the vessel.
The water stop gives the trip its practical appeal. A scenic cruise alone can become repetitive, especially for children. Here, you get a clear change of pace. You can sit with a drink during the ride, then use the stop for swimming and water play.
The cliffs and surrounding nature also provide a more memorable setting than a standard harbor swim. You are not simply stopping beside the town for a quick dip. The setting is part of Kamenjak National Park, with its coastal flora and sea life.
Bring a sensible attitude toward the timing. Forty-five minutes is enough for a swim and a look around, but it is not a long shore visit. You should not expect to wander through the park or spend hours examining every corner. The boat’s schedule controls the stop, and the captain needs to keep the return time on track.
The description also refers to a guide or mermaid accompanying you toward Golumber cave. A previous passenger reported that the mermaid was not present, so I would treat that feature as a possibility rather than a guarantee. The crew may still assist with the swimming stop, but you should not book solely for a costumed performance or special guide.
Golumber cave: interesting, but possibly quick

Golumber cave is one of the most unusual elements of the route. The idea is to approach the cave from the water and see the inside from close range, rather than simply passing the cliffs offshore.
That makes the cave a good reason to bring suitable swimwear and a towel. If conditions and timing allow, you can look toward the cave during the Kamenjak stop. The cave itself is more of a brief coastal feature than a long attraction visit.
You should also know that the stop may not give you much time inside the cave. One passenger found the stop too short to explore it properly and felt that the limitation was not made clear in advance. That is a fair concern. Forty-five minutes must cover swimming, jumping from the boat, fish watching, and the cave approach, so you may need to choose what matters most.
My advice is simple: decide before arrival whether your priority is the cave or the swim. If the water looks inviting, you may prefer to spend most of the stop swimming. If the cave is your main reason for booking, ask the crew about the timing once onboard and keep your expectations modest.

Porer lighthouse and coastal sightseeing

Porer lighthouse is included in the route, but the available information suggests that the boat may pass it rather than stop for a long look. This is still useful for a quick photograph or a sense of the coastline, but it is not a lighthouse visit in the usual sense.
That distinction matters when you compare this trip with a dedicated lighthouse cruise. You will see Porer from the boat, yet you should not expect to go ashore, tour the structure, or linger beside it. The same principle applies to the wider archipelago sightseeing: this is a moving view, not a series of long shore excursions.
I like having the lighthouse in the route because it gives the cruise another clear point of interest. But the Kamenjak swim is the stronger part of the experience. If you need to choose where to place your expectations, put the Kamenjak stop first and regard Porer as an added sight.
Drinks, music, and the practical comforts onboard

The tour includes drinks, music, and a toilet. Those details sound basic, but they matter on a three-hour boat ride, particularly when you are traveling with children.
The drinks help make the cruise feel more relaxed, and the music adds a holiday mood. The toilet means you do not have to wait until returning to Medulin. These are small comforts, yet they add real value when the boat is away from shore.
Food is not included. Plan around that before you leave. The supplied information does not specify a meal or snack service, so you should not count on lunch onboard. A morning start at 10:00 a.m. may work well for some schedules, but you may want to eat beforehand or arrange food for after the tour.
The crew also gives the experience a personal touch. A family reported that the children received gifts, which suggests that the crew may make an effort to keep younger passengers happy. I would not treat a gift as guaranteed, but families can reasonably expect a welcoming approach based on the service described.
Is $36.20 good value?

At $36.20 per person, this is fairly priced for a three-hour boat outing with a captain, crew, drinks, music, toilet access, coastal sightseeing, and a swimming stop in Kamenjak National Park.
The value is strongest if you would otherwise pay separately for transport or a boat trip to reach the park. You get several elements in one booking, and the shared format keeps the cost below a private charter. The maximum of 25 people also helps the price feel more reasonable than a crowded sightseeing cruise.
The value is weaker if you expect a full meal, a long cave visit, or a detailed lighthouse stop. Food costs extra, the Kamenjak break is limited to about 45 minutes, and Porer may receive only a passing view.
I would book it for the combination of sea time and swimming, not for a single promised feature. That way, the outing still works if the cave visit is brief or the lighthouse is seen from a distance.
Who will enjoy this Medulin excursion?

Families are a natural fit. Children get a change of scene, the boat offers music and drinks, and the swim stop gives them something active to do. The manageable group size is also more comfortable for parents than a very large boat.
You will likely enjoy it if you want an easy half-day outing from Medulin without planning each detail yourself. The captain and crew manage the route, while you get several views and a chance to swim.
It also suits couples and solo visitors who prefer a short coastal trip rather than a full-day cruise. The boat provides a social setting without requiring you to spend all day with the group.
You may want another option if your main aim is serious underwater exploration, a long visit inside Golumber cave, or a quiet private cruise. The timing is fixed, and the route covers several sights quickly.
Most people can participate, and service animals are allowed. The meeting point is near public transportation. The tour requires good weather and a minimum number of participants. If poor weather or low enrollment cancels the trip, you can choose another date or receive a full refund.
Booking and cancellation details worth knowing
You can cancel up to 24 hours before the 10:00 a.m. start for a full refund. Changes made less than 24 hours before departure are not accepted, and cancellations inside that period are not refunded.
Weather matters on this trip. If conditions are poor, the operator offers another date or a full refund. The same choice applies if the minimum number of participants is not reached.
Arrive at the Medulin Riva meeting point with enough time to find Tajana & Zlatni Rat Excursions Medulin. Your ticket is mobile, and the activity ends back at that same location.
My verdict on the Kamenjak boat trip
I would recommend this excursion if you want a relaxed three-hour boat ride with a real swimming stop, especially if you are traveling with children. The combination of Kamenjak, the archipelago, Porer lighthouse, drinks, music, and a toilet gives you a comfortable way to see more of the coast without spending a full day at sea.
Book with realistic expectations. The cave may receive only a short visit, the lighthouse may be passed rather than explored, and the advertised mermaid may not appear. Food is not included, and the 45-minute stop requires you to choose between swimming, fish watching, and spending time near the cave.
For $36.20, I see this as a good-value coastal sampler. Choose it for the overall outing, the water stop, and the ease of having a captain and crew handle the day. Skip it only if you need a long cave exploration, a full meal, or an in-depth lighthouse visit.
