Tucked away near Kobarid in the Soča Valley, Kozjak Waterfall is a stunning 15-meter cascade framed by towering limestone cliffs. The easy, well-marked trail takes you to a viewing platform where you can take in the dramatic rocky amphitheater and the sparkling pool below. While swimming isn’t allowed, it’s a perfect spot to cool off and soak up some nature. Note that there is an entry fee to visit, but you won't reach the ticket desk until you're over half way through the hike!
