Lissoughter or Lissoughter Hill [2] is a prominent hill between the Twelve Bens and Maumturks mountain ranges, at the southern entrance to the Inagh Valley, in the Connemara National Park of County Galway, Ireland. With a height of 401m (1,316feet), it does not qualify to be an Arderin or a Vandeleur-Lynam, however, its prominence of 336m (1,102feet) ranks it as a Marilyn.[3] [4] [5]
A quarry on Lissoughter's southern slopes (the Lissoughter-Derryclare quarry, named after the peak and the neighbouring Derryclare mountain), is a noted source of the green-coloured Connemara marble (sometimes called Connemara Lissoughter Marble).[2] [6] As an isolated standalone peak, it is less frequented by hill-walkers, however, it is regarded for its views of the two ranges and the southern boglands of Connemara.[7] [8]
