Rock Climbing around Osp in Slovenia, Trieste in Italy and Northern Croatia

Osp in southwest Slovenia is the undisputed centre of Slovenian climbing, attracting climbers from all over the world.  The crag is a high U-shaped wall that sits above the old picturesque village of Osp.  The quality of the limestone rock is superb with all the routes well bolted. Some of these routes are up to 140m long though there are also many single pitch routes.  The style of climbing ranges from pleasant face climbs on vertical and slightly overhanging walls with sharp positive holds, to very overhanging routes that require stamina and determination.  At Osp there are well over 200 routes across a wide range of grades.   Also close by are 2 further crags; Misja Pec with its steep powerful single pitch routes mainly in the higher grades; and Crni Kal offers single pitch routes mainly in the lower grades. 

Just across the border in Italy, there is rock climbing around Trieste, with 8 separate crags. Val Rosandra is the most extensive and it also offers some multi-pitch routes.

The climbing in northern Croatia is not as extensive as the crags around Osp and Trieste, though they do offer the best potential for developing new routes. Visit our Istria page for more information regarding these crags.

Popular Climbing Routes in Slovenia GuidebookThe Popular Climbing Routes in Slovenia guidebook describes the very best rock climbing routes in the Slovenian Mountains. This includes both mountaineering and pure multi-pitch rock climbing routes most of which are between 350m and 850m long. In total 101 routes are described covering some of Slovenia’s highest mountains such as Jalovec and Travnik. Buy this book from our shop.

Getting to this excellent region is easy, with Trieste Airport close by and Ljubljana airport is 1 to 2 hour’s drive away. The obvious place to be based is at Osp where there is a campsite (open all year round), with both Osp and Misja Pec crags within walking distance. There is also accommodation in Osp as well, such as hotels and apartments. Alternatively there are many holiday apartments to rent on the coast.

Rock climbing is possible throughout the year through the ideal time is the spring and autumn. It can be cold and wet in the winter. With regards to gear a 70m rope is ideal though many routes are possible with a 60m rope. Around 15 quickdraws are usually sufficient.
