Tempan notes that the townland on the south slopes of Garraun South Top, that runs to Kylemore Lough, is called Lemnaheltia (, meaning the doe's leap), and this name appears on Mercator's map of Ireland (1595) as Dosleape for the mountain (or the cliffs below the summit). A legend tells of Fionn Mac Cumhail's dog Bran, who pursued a doe in this area, however, when the doe leapt from the summit, Bran fell from the cliff into the lake. Many Irish places claim variations of this story, including Lough Brin (, meaning Bran's lake) south of the MacGillycuddy Reeks, in Kerry.
