Geography
Cnoc an Chuillinn lies in the eastern section of the MacGillycuddy's Reeks, Ireland's highest mountain range. It is at the start of a high ridge section that, moving eastwards, includes Cnoc an Chuillinn East Top , Maolán Buí, Cnoc na Péiste, The Big Gun and finishes with Cruach Mhór. Between Cnoc an Chuillinn, and Cnoc an Chuillinn East Top, lies a major south-east spur to the less frequently climbed, Brassel Mountain, which descends steeply into the Black Valley below. Brassel Mountain is regarded for its steep scrambling, and as an alternative access route to the eastern section of the main Reek's ridge, from more frequently used Hag's Glen options. To the west of Cnon an Chiullinn is Cnoc na Toinne, and then the drop down to the col from which the Devil's Ladder can be descended into the Hag's Glen. Cnoc an Chuillinn's name is often misspelt, including swapping the middle-"an" for "na", or using one "l" or one "n", or using the anglicised term of Knockacullion, as done in other parts of Ireland. Cnoc an Chuillinn is the 316th-highest mountain in Britain and Ireland on the Simm classification. It is listed by the Scottish Mountaineering Club as one of 34Furths, which is a mountain above in elevation, and meets the other SMC criteria for a Munro, but which is outside of Scotland; which is why Cnoc an Chuillinn is sometimes referred to as one of the 13 Irish Munros. Cnoc an Chuillinn's prominence qualifies it to meet the Arderin classification, and the British Isles Simm and Hewitt classifications. Cnoc an Chuillinn does not appear in the MountainViews Online Database, 100 Highest Irish Mountains, as the prominence threshold is over.
