 Garraun lies on an isloated massif near the mouth of Killary Harbour at the far north sector of the Twelve Bens/Garraun Complex Special Area of Conservation in the Connemara National Park in Galway.The southern slopes are a scenic backdrop to Kylemore Abbey and Kylemore Lough.Irish academic Paul Tempan notes that Garraun is clearly a name of Irish origin, either from , meaning "grove", or more likely from , meaning "fang"; while the summit is flat, the eastern ridge leading to it is sharp enough to have merited such a name.
