Medulin: Glass Boat Tour Experience to Kamenjak
Kamenjak National Park is the star here, with a 45-minute swimming stop near its rugged cliffs and the chance to look into Golumbera Cave. The glass boat adds a simple thrill for families: you can watch fish below without leaving your seat, then jump in when the water calls.
I like the easy, family-friendly setup and the way the crew handles the route while you enjoy the Medulin archipelago. I also like that drinks, music, a toilet, and a captain and crew are included. The main caution is that the stop may feel short if you want time for both swimming and a proper cave visit, and the advertised mermaid feature may not always be available.

Leaving Medulin at 10 a.m.

The boat leaves from Tajana & Zlatni Rat Excursions on Medulin Riva at 10 a.m. This is a convenient starting point if you are staying in Medulin, since the tour begins and ends at the same waterfront meeting point.
The cruise lasts about three hours, so the schedule suits you if you want a morning on the water without giving up an entire day. You can still have lunch and plan an afternoon back on land. Since the tour ends where it starts, you do not need to arrange a separate return ride.
The boat carries no more than 25 people. That is large enough to create a social atmosphere, but smaller than the packed party boats that can make swimming stops feel hurried and impersonal. You will have a captain and crew handling the practical side of the trip, leaving you free to watch the coast, listen to music, and decide how active you want to be.
The tour is offered in English. Confirmation arrives when you book, and the meeting point is near public transportation. Service animals are allowed, and the activity notes say most people can participate.

Watching the Medulin archipelago from the boat

The cruise is not only about reaching Kamenjak. The route gives you time to look across the Medulin archipelago, a group of low islands and rocky coastal scenery that makes more sense from the water than from a town street.
This sightseeing portion is a useful part of the trip because you get a broader view of the coast without needing to hire a boat or plan a complicated route yourself. The captain takes care of the movement between places, while you can settle in with a drink and follow the shoreline.
Porer lighthouse is also included in the sightseeing. Keep your expectations in check: the boat passes by the lighthouse rather than stopping there. That makes it a photo opportunity and a quick coastal landmark, not a separate visit. If you want to walk around a lighthouse or spend time near it, this trip will not provide that.
The pace is best for people who enjoy a mix of gentle sightseeing and a short active stop. It is not a full-day coastal expedition, and it is not designed around long stays at several different sites.
The 45-minute stop at Kamenjak National Park
Kamenjak National Park provides the main reason to book this excursion. The boat pauses near the cliffs for about 45 minutes, giving you time to swim, spend time in the water, or remain on board and watch the fish below.
The setting combines clear coastal water, rocky cliffs, and protected natural surroundings. You are not simply stopping at an ordinary beach. The appeal is the chance to experience the park from the sea, where the cliffs and caves become part of the view.
You can choose your own level of activity. If you are comfortable in the water, you can swim near the boat and look beneath the surface. If you prefer to stay dry, you can remain onboard and enjoy the glass-bottom view. The option to feed local fish adds a small, hands-on moment, especially for children.
I would plan this stop before you board. Forty-five minutes passes quickly once you allow time to get ready, enter the water, swim, return to the boat, and dry off. If your top priority is a long swim, you may find the stop brief. If you mainly want a taste of Kamenjak with some water time, it is a useful amount of time.
The natural setting also means you should treat this as a coastal swimming stop, not a fully equipped beach visit. The supplied details do not mention beach facilities, changing rooms, or rental equipment at the site. The boat does include a toilet, which is helpful during the wider cruise.
Looking into Golumbera Cave

Golumbera Cave is one of the more distinctive parts of the route. Accompanied by the guide, described in the tour information as a mermaid, you can look beneath the cliffs and see the inside of this coastal cave.
The cave gives the swimming break a little more character than a simple stop in open water. You get to see how the rocky shoreline is shaped from below, while the surrounding plant and animal life adds to the sense that Kamenjak is more than a swimming spot.
There is an important practical point here. The advertised mermaid feature may not be present on every departure. You should also allow for the possibility that the cave visit will be brief. A short stop can make it difficult to explore the cave properly, particularly if the boat is keeping to a fixed schedule.
That does not make the cave unworthy, but it changes how you should view it. Treat Golumbera as a quick highlight within a boat trip, not a long guided cave tour. If seeing the cave is your main reason for booking, ask the operator about current conditions and the day’s plan before departure.

Glass-bottom views and marine life

The glass boat feature is simple, but it gives the cruise a useful extra layer. You can look down from the boat and watch for fish without getting wet. On a calm day, this may be particularly appealing for children or anyone who prefers not to swim.
The tour also allows you to feed local fish from the boat. This is a small activity, not a guaranteed wildlife show. Marine life is unpredictable, so keep your expectations sensible. You might see fish close to the boat, but there is no stated guarantee of larger wildlife or constant sightings.
This is one reason the trip works well for families. Children can move between several kinds of entertainment: watching the water through the glass, listening to music, having a drink, swimming during the stop, and looking for fish. Adults get a relatively easy outing because the crew manages the boat and route.
The glass-bottom viewing should be considered an added feature rather than the entire purpose of the excursion. If you are seeking a dedicated wildlife cruise, this trip may feel too casual. If you want sightseeing, swimming, and a chance to spot fish in one outing, it fits better.
Drinks, music, and the family-friendly setup

Drinks are included, while food is not. That distinction matters. You can expect refreshments during the cruise, but you should not book this as a meal excursion or assume lunch will be provided.
One positive detail is the relaxed onboard atmosphere. Music gives the ride a holiday feel, and the included drinks mean you do not need to organize every refreshment before setting out. A previous departure also included gifts for children, but you should treat that as a possible extra rather than a guaranteed part of every tour.
The toilet onboard is another practical benefit. On a three-hour boat trip, that facility can make the outing much easier, especially for families. The tour information does not list specific drinks, so if you have dietary needs or want particular snacks, bring what you require within the operator’s rules.
The maximum of 25 people helps keep the boat from becoming too crowded. Still, this is a shared excursion. You will not have complete control over the timing, music, or swimming area. The tradeoff is a lower price and a straightforward day on the water without the cost of a private charter.
Is $36.20 a fair price?

At $36.20 per person, the value comes from combining transport on the water, Kamenjak access, a swimming break, sightseeing, refreshments, and crew support in a three-hour outing.
You are not paying only for a boat ride. The price includes a visit toward Kamenjak, a look at Golumbera Cave, views of the Medulin archipelago and Porer lighthouse, drinks, music, and use of the onboard toilet. For a family, the combination can be easier to justify than paying separately for a boat rental, route planning, and refreshments.
The value is less convincing if you expect a long stop at the cave, a close visit to the lighthouse, or a full meal. The lighthouse is passed rather than visited, food is excluded, and 45 minutes at Kamenjak leaves limited time for several activities.
I see this as a good middle-ground option. It costs less than arranging a private boat, while offering more structure than simply hiring a vessel and deciding where to go. You pay for convenience and variety, not for an extended stay at one site.
Who should book this boat tour?

I would recommend it most strongly to families, couples, and first-time visitors who want an uncomplicated introduction to the coast around Medulin. The short duration works well if you have limited time, and the choice between swimming and staying onboard lets people in the same group enjoy the outing differently.
It also suits you if you like a gentle mix of sightseeing and activity. You can sit back during the cruise, then become more active at Kamenjak. The English-language format makes the arrangements straightforward for English-speaking visitors.
You may want to choose another option if you need a long swimming session, want a proper cave exploration, or expect a guaranteed mermaid performance. You should also look elsewhere if your main goal is a lighthouse visit or a food-focused boat trip.
The tour requires good weather. If poor conditions cancel the outing, the operator offers another date or a full refund. If the minimum number of participants is not reached, you are offered another date or experience, or a full refund. For other cancellations, you need to cancel at least 24 hours before the 10 a.m. start for a full refund. Changes made within 24 hours are not accepted.
My booking advice for Medulin

Before booking, decide what matters most to you. If you want a pleasant half-day on the sea with a family-friendly swimming stop, this package makes sense. If you are focused on one specific feature, such as spending substantial time inside Golumbera Cave, confirm the current plan with Tajana & Zlatni Rat Excursions first.
Arrive ready for a shared boat outing rather than a private adventure. Bring anything you need for food, since meals are not included, and allow for the possibility that the wildlife viewing will be modest. The best moments may come from the overall mix: rocky Kamenjak cliffs, a quick look into the cave, fish beneath the boat, and the changing views around the Medulin islands.
