The experience
You arrive at the base near Slunj, get fitted with a kayak, safety gear and a neoprene suit if the water is cold, then receive paddling instructions before a short drive to the start of the canyon. The Upper Mreznica forms 15 travertine barriers in just 3km. The highest waterfall is 8 meters. Between the falls, the river pools into warm, calm water where you float and paddle gently to take in the canyon walls and the differently colored pools. At each fall, your guide directs your boat individually: some you ride down in the kayak as a natural waterslide, some you paddle around, and some you can jump into the pool below if you want the rush.
The beginning and end of the route pack the most action: waterfalls in quick succession, the choice to ride or jump, the spray and the speed. The middle section slows down: you paddle through the quiet pools, look at the rock formations, and catch your breath. Because the water between the falls is calm and there are no long paddling sections, the trip suits almost everyone: children from 6 years old, seniors, and anyone without prior kayaking experience. The guide keeps safety in focus at every drop, so the fun and the control stay together.
When you reach the finish, the base is a quick drive away. You change into dry clothes and head back. The whole outing (gear, guide, transfers, safety instruction) takes 3 hours and leaves you with the memory of riding water down a canyon most visitors to this part of Croatia never see.
Is this one for you?Most kayak trips on calm rivers mean paddling the whole way: here, the waterfalls do the moving for you, so you steer and brace while the canyon carries the boat down. The guide directs each kayak individually through the falls instead of leading a group down one route, which means you get the thrill without the crowd and the safety without the lecture.
