The experience begins with a straightforward booking process—your mobile ticket is ready to go, making it easy to plan in advance. The meeting point is at Rastoke Active, located at Donji Niki in Slunj, Croatia. From there, a comfortable van transfer takes you to Primilje, the remote starting point at the Mrenica River, saving you the hassle of navigating unfamiliar roads.
Traveling in a small group (up to 30 travelers), you’ll appreciate the convenience of transportation included in the price ($59.95 per person), which covers the ride to and from the river. This is especially valuable because the location is quite secluded, and the drive offers lovely views of the Croatian countryside.
Once at the starting point, you’ll be given all the necessary gear—waterproof equipment, helmets, wetsuits if required, and water shoes. Many reviews highlight the importance of wearing a wetsuit, especially since the water can be quite cold, even in summer.
Your guides, like Ivan, will provide detailed safety instructions and show you how to handle your kayak with confidence. One reviewer mentioned that guides are helpful and attentive, even taking photos throughout the trip, which is a nice touch for capturing memories.
The core of the adventure is a 5-kilometer (approximately 3 miles) paddle down the most beautiful stretch of the Mrenica River. Along this route, you’ll encounter a series of waterfalls—totaling nine—and three rapids. The waterfalls are particularly noteworthy, with Milkovia slap being the largest and most dramatic. Here, adventurous souls can test their bravery by jumping from the 5m or 9m high cliffs directly into the refreshing water—an optional thrill for adrenaline junkies.
Reviewers consistently mention the waterfalls and jumps as the highlight, with one stating, “the rapids and jumps were super fun,” and another praising the “proper challenging drops” and well-organized experience. The untouched nature surrounding the river, with its untouched flora and clear waters, makes each paddle stroke feel like a journey into a hidden paradise.
Between the waterfalls, there are multiple spots perfect for swimming, relaxing, or simply floating in the calm pools. Many guests appreciated the chance to cool off and unwind in these secluded areas, away from the bustling tourist spots.
The paddle concludes near a charming camp on the river, passing a picturesque bridge—providing a perfect photo opportunity. The total time on the water is roughly 2 to 2.5 hours, making it a manageable half-day activity that allows time for other sightseeing or relaxing afterward.
One of the most praised aspects of this tour is the guides. Beyond safety instructions, guides like Ivan are noted for their local knowledge, helpfulness, and friendliness. They are also skilled at capturing photos and videos, allowing you to focus on enjoying the experience without worrying about your camera.

Many reviewers mention the cold water, recommending bringing a wetsuit or warm clothing for the return journey.
