Benleagh (Irish: Binn Liath, meaning 'Grey Peak') stands at 689 metres (2,260 ft), while it does not have the prominence to qualify as an Arderin, but its prominence does allow it to rank as the 125th–highest peak on the Vandeleur-Lynam scale. Benlagh is situated in the southern sector of the Wicklow Mountains, and is part of the large massif of Lugnaquilla 925 metres (3,035 ft), Wicklow's highest mountain.

Benleagh's southern flank forms the steep walls and cliffs of the hanging valley of Fraughan Rock Glen, which then falls into the U-shaped valley of Glenmalure below; Benleagh forms a "horseshoe" around the Fraughan Rock Glen with Lugnaquillia at its apex and Cloghernagh 800 metres (2,600 ft), to the south. Benleagh also sits on a broad "spine" that links Lugnaquilla in the south, to Camenabologue and Table Mountain to the north, which circle the Glen of Imaal.
