The guides will lead the way, ensuring everyone feels comfortable whether you’re a beginner or a seasoned paddler.
The Waterfalls and Swimming Stops
The highlight for many is the series of waterfalls along the route, especially the Milkovia slap, the largest on the river. After navigating past the initial waterfall, you’ll encounter this stunning cascade, which offers a perfect spot for a swim or a jump if you’re feeling brave. Reviews rave about the jumps—some travelers even tried from 7 meters, feeling that adrenaline rush firsthand.
Paddling over small waterfalls and stopping at various points for swimming and relaxation is a big part of the trip. The water is crystal clear and refreshingly cold, making it a perfect way to escape the summer heat. The guides are keen on ensuring safety, but the jumps do add an element of thrill—so you should be comfortable with jumping into deep water from height.

This spot often feels like a hidden gem, with peaceful surroundings that invite a moment of calm after the adventure. The entire route is designed to maximize your interaction with nature, providing plenty of opportunities to pause and soak it all in.
