Maolán Buí (Irish for "yellow/golden round knoll"), also known by the name Bearna Rua,[2] at 973 metres (3,192 ft) high, is the fifth-highest peak in Ireland on the Arderin list, or the sixth-highest peak in Ireland according to the Vandeleur-Lynam list.

Maolán Buí is in the eastern part of the MacGillycuddy's Reeks in County Kerry, Ireland's highest mountain range.

[3] A narrow north-west spur of Maolán Buí called The Bone, not to be confused with the nearby peak that sits on the Beenkeragh Ridge, The Bones 957 metres (3,140 ft), is regarded as a safe escape route from the eastern section of the main MacGillycuddy's Reeks ridge, down into the Hag's Glen and out through Cronin's Yard.

[5] It is regarded by the Scottish Mountaineering Club ("SMC") as one of 34 Furths, which is a mountain above 3,000 ft (914.4 m) in elevation, and meets the other SMC criteria for a Munro (e.g. "sufficient separation"), but which is outside of (or furth) Scotland;[6] which is why Maolán Buí is sometimes referred to as one of the 13 Irish Munros.

[5] Maolán Buí does not appear in the MountainViews Online Database, 100 Highest Irish Mountains, as the prominence threshold is over 100 m (328 ft 1 in).
