Geography

Rocky summit of the Big Gun (left), and ridge to Cnoc na Péiste (right)

The Big Gun is in the eastern section of the MacGillycuddy's Reeks in County Kerry, Ireland's highest mountain range.^[3] It is on a narrow rocky arête between the mountains of Cnoc na Péiste 988 metres (3,241 ft) to the southwest, and Cruach Mhór 932 metres (3,058 ft) to the north, and is considered as offering some of the most exposed and serious hill walking in Ireland (equivalent to The Bones on the nearby Beenkeragh Ridge).^[4][5][3]

Because of its positioning, The Big Gun is usually climbed as part of a horseshoe, or loop-walk, of the eastern section of the Reeks, starting and ending from the Hag's Glen.^[4][3] It is also climbed as part of the even longer MacGillycuddy's Reeks Ridge Walk, which often starts at The Big Gun's eastern end, from Kate Kearney's Cottage in the Gap of Dunloe.^[6]

The Big Gun is the 378th-highest mountain peak in Britain and Ireland on the Simm classification.^[7] It is regarded by the Scottish Mountaineering Club ("SMC") as one of 34 Furths, which is a mountain peak above 3,000 ft (914 m) in elevation, and meets the other SMC criteria for a Munro (e.g. "sufficient separation"), but which is outside of (or furth) Scotland;^[8] which is why The Big Gun is sometimes referred to as one of the 13 Irish Munros.^{[citation needed]}

The Big Gun's prominence qualifies it to meet the Arderin classification, and the British Isles Simm and Hewitt classifications.^[7] The Big Gun does not appear in the MountainViews Online Database, 100 Highest Irish Mountains, as the prominence threshold is over 100 m (328 ft).^[9]
