Overview

About Slap Kozjak

Slap Kozjak is a stunning 15-meter-high waterfall hidden within a rocky gorge in the Kobarid Forest of Slovenia. It originates from the Kozjak stream, a tributary of the famous Soča River.

The stream carves its way through a narrow gorge before plunging into a deep, emerald pool, creating a secluded and mystical atmosphere that makes Slap Kozjak one of Slovenia’s most scenic natural places. Despite gaining popularity in recent years, it still feels like a well-kept secret, with an otherworldly vibe.

The hike to Slap Kozjak is just as remarkable as the waterfall itself. It takes you along the turquoise waters of the Soča River, across picturesque bridges, and past scenic creeks. It’s not a demanding hike and is officially open from April 2nd to October 31st.

How to get there

To get to Slap Kozjak, you’ll first have to get to Parking Kozjak, Parking Kozjak 2, or Kamp Koren, from where you can start the hike to the waterfall.

As Slap Kozjak is located in the Goriška-Tolmin region, which is relatively remote compared to other areas of Slovenia, there are not many public transportation options available in this area. That’s why the easiest way to get to Slap Kozjak is by car. This also gives you the flexibility to visit more beautiful places in Slovenia during a nice road trip. If you don’t have your own car, we highly recommend you rent a car with RentalCars.com or a Campervan with Roadsufer.
