It is the highest peak of the Krn Mountains, a sub-chain of the southwestern Julian Alps.

The Soča River flows to the west of the peak, while the smaller Lepenjica and Tolminka pass northeast and southwest of it.

On the southern slope of the mountain lie the small villages of Vrsno, Krn, Drežnica, Drežniške Ravne, and Magozd.

The 3rd Regiment of Alpini had taken Krn's peak on 16 June 1915 in a daring raid, where the elite Italian unit climbed its cliffs "with their boots swaddled in sacks of straw to reduce noise,"[2] some of them barefoot, and others wearing only socks,[3] and battled the Hungarian battalion of the 4th Honved Regiment.

"[5] The top of neighbouring Mount Batognica (2,164 m or 7,100 ft) was blown off by an accidental weapons-depot explosion during the war.
