The Climbing without Frontiers Guidebook covers 3 different countries, Slovenia, Italy and Croatia on the Adriatic Coast. It covers; the crags of Osp, Misja Pec and Crni Kal in Slovenia; 8 crags around Trieste in Italy; and 20 crags in Istria in Croatia. This compact area makes for a great climbing holiday across these 3 countries, with over 2,800 routes across a wide range of grades.
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. The most extensive crag is Val Rosandra with over 500 routes, followed by Napoleonica with over 250 routes. Both crags provide a good range of routes on limestone rock with some multi-pitch routes available at Val Rosandra.
South of Slovenia is the northern Croatian region of Istria. This region is a popular holiday destination in Croatia around the towns of Pazin, Pula and Rovinj. In total there are 20 crags in this area, with over 1,100 sport routes that are well bolted and on solid limestone rock. The 3 largest crags are Kompanj, Limski kanel, and Rovinj.
