Ojstrica (2,350 m, IV.) is one of the most prominent peaks of the Kamnik–Savinja Alps, rising east of the Kamniško sedlo pass, where the ridge unfolds into sharp, rugged forms. Its pyramidal silhouette towers above two completely different landscapes: the glacial Logar Valley to the north and the high‑mountain karst field of Korošica to the south. This duality – the glaciated north and the karstified south – gives Ojstrica exceptional spatial and geomorphological distinctiveness.
The mountain is built of Triassic limestones and dolomites, heavily fractured and karstified. Its slopes feature limestone pavements, gullies, fissures, and small depressions, while the wider area contains several caves and shafts, confirming the intensity of karst processes in the high‑mountain environment. South of Ojstrica lies Korošica, an open grassy piedmont karst field framed by the steep walls of Ojstrica, Planjava, and Lučka Kopišnica. To the north, the terrain drops abruptly into the upper part of the Logar Valley, revealing high walls, scree slopes, and remnants of glacial reshaping.
Approaches to Ojstrica are varied. The most frequented route leads from Kamniško sedlo along a scenic ridge and is technically moderate. The southern approach from Korošica crosses grassy slopes and joins the ridge route higher up, while the northern approach from the Logar Valley is the longest and most demanding, involving a large elevation gain and traversing northern scree fields. The ridge connection across Škarje is exposed and partly climbing in character, suitable for experienced mountaineers.
The north face of Ojstrica is one of the most striking walls in this part of the Alps – high, steep, and long considered an alpinistically demanding challenge. In the author’s family history, this wall holds a special place: in the 1930s it was climbed by his grandfather, Franc Burger from Celje, one of those quiet, modest alpinists who never recorded their ascents in chronicles and never sought recognition. His ascent survived only as part of family oral tradition, yet such stories form the living, informal layer of Slovenian mountaineering history – the one passed down through generations and preserved in family memory.
Because of its position, relief expressiveness, and wide views, Ojstrica is one of the key peaks of the eastern part of the high‑mountain core of the Kamnik–Savinja Alps. From the summit, the view opens toward the Logar Valley, Korošica, Planjava, Brana, Turska gora, Skuta, and eastward toward the Dleskovec Plateau and Raduha. The mountain combines elements of Alpine highlands, karst landscapes, and remnants of former pastoral use, creating a diverse, distinctive, and culturally rich mountain environment.
