It is the 432nd-highest mountain, and 21st most prominent mountain, in Britain and Ireland, on the Simms classification. Lugnaquilla is regarded by the Scottish Mountaineering Club (SMC) as one of 34 Furths, which is a mountain above in elevation, and meets the other SMC criteria for a Munro (e.g. sufficient separation), but which is outside of (or furth) Scotland; which is why Lugnaquilla is referred to as one of the 13 Irish Munros.
