Parc national du Connemara

Connemara National Park (Irish: Páirc Naisiúnta Chonamara) is one of six national parks in Ireland that are managed by the National Parks and Wildlife Service of the Department of Culture, Heritage and the Gaeltacht. It is located in the west of Ireland within County Galway.

Diamond Hill (Irish: Binn Ghuaire, meaning 'Guaire's peak') at only 442 metres (1,450 ft), does not rank as an Arderin, or a Vandeleur-Lynam; however, it has the prominence to rank as a Marilyn. Diamond Hill is an isolated peak, situated beside the village of Letterfrack, in the northwest corner of the Twelve Bens in the Connemara National Park in Galway, Ireland.
