Entering The Gorge: What to Expect

The trip begins in Zecev Varoš, a small village about 10 minutes from Slunj, where the host’s eco-friendly wooden house signals the start of your adventure. After a brief safety briefing—crucial for first-timers—you’ll get outfitted with wetsuits, helmets, life jackets, and waterproof barrels. The guides, who speak English and Croatian, are friendly and professional, and they take care to ensure you feel comfortable before heading into the gorge.
Paddling in a two-person inflatable kayak means you don’t need previous experience.

Expect to spend around 3 hours on the water, with breaks to rest, enjoy the scenery, swim beneath waterfalls, or just soak in the tranquility of the canyon. The entire route in the upper Mreznica River is carved with white rocks and lush greenery, creating a landscape that’s both dramatic and peaceful. One reviewer noted, “The instructor was very, very good, we were delighted with him and the private tour,” which speaks to the quality of guiding you’ll encounter.

Probably the most talked-about aspect is the opportunity to jump from cliffs into the refreshing river—an adrenaline rush that even non-swimmers can enjoy with proper guidance.

Climbing waterfalls is also part of the experience, offering a hands-on way to connect with Croatia’s rugged terrain.
Swimming beneath waterfalls and in the calm sections of the river offers a welcome cool-down and a chance to relax after paddling. These moments of downtime amid the exciting scenery create a great balance, especially for those who prefer adventure with a touch of serenity.
