Kočna is a mountain massif, part of the Grintovci in the Kamnik-Savinja Alps. The massif is located west of mount Grintovec and consists of the peaks of Na Križu (2484 m n.v.), Kokrska Kočna (2520 m n.v.) and Jezerska Kočna (2540 m n.v.), which is immediately after Grintovec (2558 m n.v.) the highest peak of the Kamnik Savinja Alps.
Na Križu (2484 m n.v.) it was originally considered to be the highest peak of Kočna massiv and was originally called Kokrska Kočna. Access is via a path to the left of the marked path under the saddle between the south-western Kočne. At the top are the remains of a former inscription box (from the 80s of the 20th century), and access is very risky due to the very crumbling terrain above the precipice walls.
