What to Expect from the Trip

When you hop on this boat from Medulin Harbour, your first impression is how easy it is to find the meeting point, marked by a bright blue parasol and a friendly team ready to assist. The vessel itself feels comfortable, and since it’s a small-group experience, you won’t be packed in like sardines.
The trip kicks off with a panoramic drive around the Medulin archipelago. As you cruise along, the boat’s glass bottom provides a peek into the seabed—an especially fun feature if you have kids, who will love watching the colorful fish swim beneath. We’ve seen reviews where guests mention that feeding the fish during the stop is a highlight, and you’ll likely enjoy that too.
Next, the boat anchors near the cliffs of Kamenjak for some swimming and exploration. Here, the main attraction is the hidden cave of Golumber—a small but intriguing spot for those interested in a quick cave visit. However, some reviews pointed out that the cave visit can be brief, so don’t expect a long spelunking session.
One of the biggest sights is the Porer lighthouse, which was built during the Austro-Hungarian era in 1846. While the guide will point it out, some guests noted that they didn’t get as close as they expected, with one reviewer stating, “we only saw the lighthouse from a distance.” Still, it’s a lovely photo opportunity, especially at sunset or on clear days.
Swimming and Fish Feeding is another highlight, with the boat stopping for a swim in the protected waters of Kamenjak, where the clear, calm sea makes for an easy, relaxing dip. Feeding the fish is simple and fun, and many kids love the chance to interact with the marine life. Just keep in mind, the time for swimming isn’t extensive—roughly 40 minutes—so plan your expectations accordingly.

The route begins at Medulin Harbour, where your crew will gather everyone and do a quick safety briefing. From there, the voyage takes you around the Medulin archipelago, offering scattered views of small islands and rocky formations. The panoramic drive provides beautiful vistas for photos—so don’t forget your camera or phone.
As the boat reaches the cliffs of Kamenjak, you’ll get a chance to see the Golumber cave, a tiny hidden spot within the cliffs. Some reviews mention that the cave is more of a quick peek than a full-on exploration, but it’s a neat feature for those interested in a snapshot or quick adventure.
The Porer lighthouse is visible from a distance, and while some guests hoped for a closer look, most agree it’s still impressive as a historic landmark. Built in 1846, it remains one of Croatia’s largest lighthouses and is an iconic sight on the coastline.
The swimming stop gives you a chance to float in the protected waters, which are known for their clarity and calmness. During this time, the fish feeding activity begins, adding a playful element especially appealing to children.
