Ojstrica, Mountain summit in Kamnik Alps, Slovenia.

Ojstrica stands at 2,350 meters elevation with a distinctive pyramid-shaped peak composed primarily of limestone, featuring steep walls and dramatic escarpments that descend toward the Logar Valley and Roban Cirque.

Ojstrica's north face drops 600 m to the floor of the Logar Valley, and its east slope falls into Roban Cirque; the ridge links northeast over Škrbina to Krofička (2,083 m). The Slovene name comes from oster, 'sharp', for the pointed summit. Marked ascents start from Kocbek Lodge at Korošica (1,808 m), the Kamnik Saddle Lodge (1,864 m) and the Klemenšek Cave Lodge (1,208 m).

The name Ojstrica comes from the Slovene word oster, 'sharp', for the pointed summit seen from far off. The Slovene name is used in mountaineering writing and on maps, and the peak appears on the list of Slovene two-thousanders and on the Slovene Mountain Trail.

Approaches start from Kamniška Bistrica (601 m), the Logar Valley (761 m) or Roban Cirque (about 700 m). From the Kocbek Lodge at Korošica (1,808 m) the southern route takes 1½ hours and the eastern ridge 2¼ hours; from the Klemenšek Cave Lodge (1,208 m) it is 3 hours via Škrbina or 3½ hours via Škarje.

The Slovene name comes from oster, 'sharp', for the pointed summit. The ridge continues northeast over Škrbina to Krofička (2,083 m), and southwest over Škarje and Lučka Baba (2,244 m) toward the Planjava massif (2,394 m). The southern scree slope drops to the Korošica basin.
