Lough Inagh is located about east of Clifden on the R344 road in the Inagh Valley. The Twelve Bens range lies to the west of the lake, with Derryclare and Bencorr directly overlooking the lake. The bulk of the Maumturks range and its long central spine lies to the east of the lake, with two highest peaks of Letterbreckaun and Binn idir an Dá Log , also overlooking the Lough.
