Prisojnik (also known as Prisank) is a majestic, stretched-out mountain rising right above Vršič Pass. If you have ever driven through Vršič Pass in Slovenia, you have certainly noticed the dominant rocky peaks that tower over the mighty Julian Alps.
Prisojnik is one of the most impressive mountains in the Slovenian Julian Alps. Its enormous north wall is clearly visible from Kranjska Gora and Vršič Pass. Two well-secured via ferrata routes lead to the summit, offering the perfect mix of challenge and excitement for experienced mountaineers and ambitious amateurs.
Hiking directions
There are several ways to reach the top, including two popular via ferratas: Hanzova pot and Kopiščarjeva pot. The ascent described here follows Kopiščarjeva pot (also called Jeseniška staza), the route that climbs the northern wall through the famous “Window” (Črez Okno) and usually descends via the easier southern Slovenska pot.
- Starting point Vršič Pass (1,611 m) on the Kranjska Gora–Bovec road. You can also start from Erjavčeva koča mountain hut (1,525 m) or the parking lot at Vršič Pass.
- Access to Vršič Pass: From the Ljubljana–Jesenice motorway, take the exit toward Kranjska Gora and continue on the regional road to Kranjska Gora. From Kranjska Gora, follow the provincial highway toward Bovec and drive up to Vršič Pass — the starting point of this trip.
We drove to Vršič Pass by car. The trail begins along a macadam road that passes Poštarski dom na Vršiču and leads to the first important intersection. There you will see the signpost “Prisojnik skozi okno” — the marker for the “iron” Kopiščarjeva pot we chose for the ascent.
Ascent: Vršič Pass – Prisojnik via Kopiščarjeva pot
This route starts from Poštarski dom na Vršiču (1,690 m) and climbs to Prisojnik summit (2,547 m) along the northern wall via ferrata, passing through the famous Okno (Window). The trail is named after the legendary mountaineering guide Anton Kravanja – Kopiščar (1889–1953) from Trenta and is maintained by the Mountaineering Association of Jesenice. It is considered the most technically demanding secured climbing route in the Slovenian Alps — a true vertical adventure full of imagination.
The path first winds through a beautiful larch forest, then mixes rock and grass until the real climbing begins. Ropes, steel cables, and wedges become very welcome here.
1. Vršič Pass – Črez Okno (through the window) passage from Poštarski dom (1,690 m)
Follow the marked path with excellent views of the iconic “Ajdovska deklica” (Pagan Girl) rock face on the north wall. The route descends slightly and traverses through lovely larch forest toward the wall. In about 30 minutes, you reach the entrance to the climbing section — and it immediately becomes clear that Kopiščarjeva pot is no easy stroll.
The climbing starts with an exposed vertical section, which later becomes a bit easier. Then it leads down a narrow ledge to the most demanding part. You climb very steeply, often right on the edge with bottomless drops below. Some sections are overhanging and require careful manoeuvring — especially the infamous 15-metre “chimney” where many people take off their backpacks and push them ahead. You really need to crawl in places.
Further on, there are fewer real difficulties, but many exposed shelves demand constant attention. The route is very dynamic — several attractive verticals, exceptional views, and a huge sense of achievement. When you start feeling the cold wind and water drops, you know you are approaching the area under the famous window.
Črez Okno (the Window) is one of the most photographed and legendary passages in Slovenia and the entire Alpine–Adriatic region. This perfectly round rock window is a true paradise for climbers and via ferrata lovers. Standing at the bottom, you feel tiny and powerless. Be careful — the rock inside the window is often slippery, small loose stones fall from above, and the exit climb is steep and tricky.
2. Črez Okno – Prisojnik summit
Just after entering the passage, you climb iron steps over smooth, well-secured rock to reach the ridge. From there, follow the airy ridge path — often very exposed on both sides — all the way to the top. There are more opportunities to rest after the Window, as the trail becomes less demanding. The ridge is spectacular, open, and incredibly scenic. The summit rewards you with breathtaking 360° views of the Julian Alps giants: Triglav, Škrlatica, Razor, Jalovec, Mangart, and many more. Total ascent time: about 4 hours.
3. Descent: Slovenska pot
There are several descent options. We chose Slovenska pot (southern route), which leads back to Vršič Pass over the southern slopes of Prisojnik. This route is not too long, very scenic, and relatively straightforward. A few more exposed passages are protected by steel cables, but most of the way follows gentle grassland slopes down to Vršič Pass.
Enjoy this epic Julian Alps classic — it’s worth every step!
Trek Goat tips for a slow ascent
- Gear up: A via ferrata set and helmet are mandatory. Gloves are helpful on cold cables.
- Timing: Early autumn is ideal—dry rocks, fewer crowds, and stable weather.
- Pace wisely: Take your time. This is a route to experience, not merely endure.
- Don’t skip the Okno: It’s the heart of the hike. Pause, look through, and soak in the view.
