The waterfall is technically a series of six waterfalls, though only the final 15-meter cascade is easily accessible to the public.
The emerald color of the pool is caused by the light reflection off the high limestone walls and the high concentration of minerals in the water.
The gorge was significantly impacted by the First World War, and remnants of military bunkers can be found along the approach trail.
The narrow stone cavern protects the waterfall from direct sunlight, maintaining a microclimate distinct from the surrounding valley.
Waterfall Kozjak is a 15-meter-high cascade located within a secluded, amphitheater-like limestone chamber near Kobarid, Slovenia. The waterfall is fed by the Kozjak stream, a tributary of the Soča River, which creates a striking turquoise pool at the base. Access requires a 20 to 30-minute hike through a narrow gorge featuring wooden walkways and suspension bridges. The site is a protected natural monument situated within the Soča Valley. The temperature of the water remains cold year-round, typically below 10 degrees Celsius. The area is geologically part of the Julian Alps, characterized by karst limestone formations.
From the wooden viewing platform at the end of the trail, which provides a direct head-on view of the waterfall and the cave opening.
Wear footwear with high-traction soles as the wooden walkways and stone paths become very slippery when wet.
Bring a waterproof casing for your camera or smartphone, as the spray inside the limestone cave is significant.
The trail starts near the Napoleon Bridge; ensure you account for the walking time from the parking area to the gorge entrance.
Do not attempt to climb the damp, moss-covered limestone walls surrounding the pool, as they are unstable.
Access may be limited or restricted during periods of heavy rainfall or high water levels due to trail safety.
Swimming in the pool at the base of the waterfall is strictly prohibited to preserve the ecosystem and ensure visitor safety.
