Taking a boat trip around Croatia’s Istrian coast is a popular way to see the natural beauty up close, and the Glass Boat Tour to Kamenjak from Medulin offers a friendly, family-oriented introduction. While not overly long, this three-hour journey packs in several highlights—like the chance to peek into Golumber cave, feed local fish, and snap photos of the iconic Porer lighthouse. As someone who appreciates authentic experiences, I find this tour a solid choice for those looking for a quick, scenic outing that’s especially suitable for families or travelers wanting a relaxed, manageable adventure.
Two things I really like about this experience: First, the friendly crew and guides seem genuinely engaged, making sure children and adults alike feel included and safe. Second, the opportunity to explore Kamenjak’s protected waters and caves gives a sense of discovery that’s hard to beat in such a short trip. Plus, the inclusion of drinks and music adds a nice, casual vibe to the ride.
A possible drawback? The route isn’t fixed and can vary depending on the day’s weather or sea conditions. If your main goal is to see the lighthouse or snorkel with special marine life, you might find this trip somewhat limited, as the reviews suggest the itinerary focuses more on swimming, cave exploring, and fish-feeding. Still, if you’re after a fun, short outing with family-friendly activities, this tour hits the right notes.
Key Points / Takeaways

- Family-Friendly: Designed with kids in mind, with opportunities for swimming, fish-feeding, and short boat rides.
- Guides and Crew: Noted as very warm and accommodating, with special mention of the lively “mermaid” guide who interacts with children.
- Flexible Route: The boat’s itinerary may change based on weather, so don’t expect a fixed lighthouse or cave visit every time.
- Value for Money: At around three hours, the price includes drinks, music, and the chance for a swim—offering good value for those wanting a quick trip.
- Limited Accessibility: Not suitable for wheelchair users or those with certain health issues like seasickness or heart problems.
- Short but Sweet: Ideal for travelers who prefer a compact experience without long boat rides or extensive planning.
If you’re a family with young children or someone looking for a short, relaxed boat experience that involves fun activities like fish-feeding and cave exploration, this tour may be a good fit. The enthusiastic guides—especially the mermaid—bring a playful element that kids seem to love, making it a memorable outing for families. The scenic views of the Medulin archipelago and Porer lighthouse add an adventure feel, even if the route isn’t always the same every day.
For travelers who appreciate authentic, unpretentious experiences without the fuss of longer excursions, this tour offers a nice balance of sightseeing and leisure. Keep in mind that it’s not the best choice if you’re eager to see the lighthouse or explore every cave, as the route varies and is somewhat weather-dependent. The three-hour duration also makes it appealing for those who dislike long boat trips or have limited time in the area.
If you’re traveling solo or with friends and want a casual, guided cruise with drinks, music, and a chance to swim, this trip hits the mark. However, if you’re looking for a more comprehensive exploration or specific sights, you might want to consider other longer tours.
Itinerary Breakdown: What You Can Expect

Starting from Medulin Harbour, you’ll meet your crew at a designated advertising desk near the large dark blue parasol—look for the friendly team ready to assist. Once aboard, the boat’s panoramic drive offers spectacular views of the coastline and the boat’s seabed glass bottom, allowing everyone to observe underwater life without getting wet. This is especially engaging for children, who can watch the fish swim beneath the boat as they float in the protected waters of Kamenjak’s Nature Park.
The first highlight is usually a visit to the Golumber Cave, hidden within the cliffs—an exciting chance for kids to explore a cave while the boat anchors nearby. The crew often encourages fish-feeding activities, where you can toss food into the water and watch a multitude of local Adriatic fish gather around. This simple, interactive activity is often praised by reviews, with one guest noting, “My daughter liked it,” and another describing the fish-feeding experience as fun and engaging.
The Porer lighthouse, built in 1846, is a key point on the route, often visible from the boat, and photographed by many. However, as some reviews mention, the lighthouse route may vary depending on weather or the captain’s discretion. If the weather turns bad, the captain might change plans for safety reasons, which is standard practice but can be disappointing if you hoped to get close to it.
Swimming in the crystal-clear waters of Kamenjak is another highlight, with the opportunity to dive in and enjoy the underwater scenery. The crew sometimes features a mermaid guide who swims underneath the boat, offering a whimsical touch that children find delightful.

Julia’s review describes the staff as “very nice and helpful,” which makes a big difference when traveling with kids or in a short time frame. The music and drinks onboard create a relaxed atmosphere, making the trip feel more like a fun outing than a formal tour.
From a practical standpoint, the three-hour duration is just right for a quick getaway—long enough to see some sights and enjoy swimming, but not so long that you’ll get bored or exhausted. The meeting point at Medulin Harbour is straightforward, with check-in 30 minutes early, and the boat ride itself is suitable for most age groups, except those prone to seasickness or with mobility issues.
Who Should Consider This Tour?

This trip is ideal for families with young children, as it combines gentle boat rides with interactive activities like fish-feeding and cave exploration. If your priority is short, relaxed sightseeing without extensive travel or walking, this fits well into a busy Croatia itinerary.
It also suits newcomers to the coast who want a taste of the local scenery without the commitment of a full-day excursion. The tour’s informal, friendly atmosphere and lively guides make it accessible and enjoyable for first-time visitors.
Price and Value Analysis

At a modest price point for three hours, including drinks and entertainment, this tour offers reasonable value. While some reviews point out that the route might not include every feature promised (like the lighthouse), the core activities—swimming, cave exploring, and fish-feeding—are well-executed and worth the cost for many.
If you’re comparing this to renting your own boat, keep in mind that the guidance, safety, and included amenities can outweigh the extra flexibility, especially if you’re not familiar with the coast or don’t want the hassle of navigation.
