Other popular, but more serious, routes to Carrauntoohil from the Hag's Glen are via the Hag's Tooth Ridge up to Beenkeragh, and then across the Beenkeragh Ridge to Carrauntoohil; or via the Eagle's Nest route to Lough Cummeenoughter, Ireland's highest lake, and up to the summit via Brother O'Shea's Gully or Curved Gully.
