[4][5] Benbreen lies in the southern end of the Twelve Bens mountain range in the Connemara National Park in County Galway, Ireland.

[5][6] Benbreen's profile is of a "high narrow rocky ridge with several summits", than a typical "peaked mountain".

[5][10] Benbreen is most often climbed as part of the popular 16–kilometre 8–9 hour Glencoaghan Horseshoe, considered one of Ireland's best high-grade hill-walking routes.

[7][8][9] Benbreen is also climbed as part of the even longer Owenglin Horseshoe, a 20–kilometre 10–12 hour route around the Owenglin River taking in over twelve summits;[11][12] Benbreen's northeastern cliffs have multi-pitch rock-climbs with grades from Diff (D) to Moderate Severe (MS), and length ranging from 40 to 130 metres.

[13] Some of the first ascents date from the mid 1980s, and noted routes include Blind Faith (S 3a, 4a, 3a, 80 m), and Stoned & Starving (S -, 4a, 75 m).
