Climbing in Slovenia, from the walls of Osp to Alpine via ferratas

Osp, the big climbing area

Osp is a village of around two hundred people in the hinterland of Koper, beneath the walls of the Karst edge. The tourist board’s Koper page puts the number of routes along that band of limestone at more than 800, and the national board describes Osp as one of Europe’s most celebrated natural climbing areas, the place that has drawn the world’s best for decades and helped shape modern sport climbing. Janja Garnbret, an ambassador for Slovenian tourism, calls it her favourite and has climbed one of its legendary lines there, Za staro kolo in majhnega psa.

Koper also hosts rounds of the sport climbing World Cup and has them secured until 2028. If you want the villages and vineyards around it, they’re in Slovenian Istria.

Climbing in the Soča Valley

Around Bovec, Kobarid and Tolmin there are plenty of bolted sectors. The Soča Valley tourist board says mid grades dominate and the hardest route is currently 8a, so it’s more about enjoying climbing in beautiful surroundings than chasing numbers. They suggest checking the published guides and the current state of each route before you go. On rest days the same villages are where the rafting and canyoning agencies are based. The valley itself has its own page, the Soča Valley.

Via ferratas if you’ve never climbed

This is the way in for most people. In the Upper Sava Valley the tourist board lists the Grančišče via ferrata at Mojstrana and another at Gozd Martuljek, and in the Soča Valley a family route from the Kanin cable car to the Prestreljenik rock window. The FCDO is clear that you need a harness and helmet, and I’d add that a guide is well worth it the first time.

Once your dates are set, check which hotels are still free in Piran before prices climb.

Proper alpinism

At the head of the Vrata valley above Mojstrana stands the north face of Triglav, which the tourist board describes as one of the great challenges for Alpine climbers in Europe. That’s real mountaineering terrain, not a day hike, which is why I deal with it separately under Mount Triglav.

What I’d choose

If you sport climb, I’d go to Osp in spring or autumn and pair the rock with the Adriatic. If you don’t, a guided via ferrata in the Julian Alps is the sensible way to try vertical ground without taking chances. Either way, what I like about Slovenia is that the rock is close to villages with good food and somewhere to sleep.
