The mountain lies to the southwest of Carrauntoohil, Ireland's highest peak at 1,038.6 metres (3,407 ft 6 in), in the MacGillycuddy's Reeks range in County Kerry.
[3][4] Caher is often climbed as part of the Coomloughra Horseshoe, which takes 6–8 hours and is described as "one of Ireland’s classic ridge walks".
[5] It takes in the circuit of neighbouring peaks of Caher West Top, Carrauntoohil, The Bones, Beenkeragh, and Skregmore.
On Caher's western slopes is the townland of Derrynafeana (Irish: Doire na Féinne, meaning 'oak wood of the Fianna').
[8] Caher does not appear in the MountainViews Online Database, 100 Highest Irish Mountains, as it is below the required the prominence threshold of 100 m (328 ft).
