Kozjak Falls, Natural waterfall in Kobarid Municipality, Slovenia

Kozjak Falls drops about 15 meters into a limestone chamber, forming a pool with green and blue reflections created by mineral-rich water. The water flows within a natural cave where moss covers the walls, creating an enclosed space around the cascade.

The stone bridge at the confluence of the Kozjak and Soča, near the first waterfall Mali Kozjak, dates from 1895. The trail from Kobarid starts at Napoleon Bridge and passes caves that are remains of the First World War. Since June 2019 the Municipality of Kobarid charges a tourist infrastructure fee for visiting the waterfall.

The Kozjak stream forms six waterfalls between Kobarid and the Soča, and the second, Veliki Kozjak, is the best known. Since June 2019 the Municipality of Kobarid has collected a tourist infrastructure fee for viewing the falls, and the trail passes several caverns left from the First World War.

A marked trail from Kobarid center leads to the falls, with the hike taking roughly 45 minutes one way. The ground can be slippery, especially after rain, so proper footwear is recommended.

The Kozjak stream drops over six waterfalls, but only the two lowest can be reached on foot; the four upper falls have no marked trail. The main fall carved a chamber resembling a karst cave, and its collapsed ceiling left the dark green pool below.
