Although the Reeks are not particularly known for their advanced rock climbing (e.g. unlike Ailladie in Clare, or Fair Head in Antrim), the east face of Carrauntoohil, looking into the Hag's Glen, and the north-east face, looking into Brothers O'Shea's Gully, have a number of multi-pitch, mixed route, rock climbing routes.
The most well-known is the 450-metre (1,480 ft) Howling Ridge (climbing grade Very Difficult, or V-Diff), which starts at the base of the gap of Heavenly Gates, and takes the arête between Carrauntoohil's east and north-east faces.

These same east and north-east faces are also used for winter climbing, conditions permitting, and seven routes of climbing grade V are marked amongst almost eighty routes in total.
