Beenkeragh is also accessed from the south-east via the Hag's Glen by ascending the Hag's Tooth , and continuing up the steep and rocky Hag's Tooth Ridge to the summit of Beenkeragh. The route gives views into the deep corrie at the base of Carrauntoohil's north-east face, known as the Eagle's Nest area. The Eagle's Nest corrie consists of three levels, with the top level (or third level), containing Lough Cummeenoughter, Ireland's highest lake. On summiting Beenkeragh, the route crosses the Beenkeragh Ridge to Carrauntoohil and descends via the Heavenly Gates path across the east-face of Carrauntoohil.
