The rock climbing at Osp actually consists of 3 different crags; Osp itself with its razor-sharp slabs, and technical vertical and slightly overhanging walls that offers both single and multi-pitch routes; 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 4 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 Climb-Croatia pages for more information regarding these crags.
All the routes in this region are on limestone rock that is generally good quality.
