Derryclare (Irish: Doire Chláir, meaning "oak-wood of the plain") is a mountain located in the Twelve Bens range in the Connemara region of County Galway, Ireland. Standing at an elevation of 677 meters (2,221 feet), it is classified as a Marilyn and a Hewitt, and it serves as the southeastern anchor of the mountain range.
Geography and Topography
Derryclare is situated at the entrance to the Glencoaghan Valley. It is characterized by its steep eastern slopes which descend toward Derryclare Lough and the N59 road. To the west and north, it is connected to the neighboring peak of Binn Ghabhar (Benghower) by a high, narrow col. The mountain is primarily composed of Dalradian quartzite, a common geological feature of the Twelve Bens, which gives the peaks their distinctive light-gray color and rugged appearance.
Ecology
The mountain and its surrounding environment are part of a sensitive ecosystem. At its base lies Derryclare Wood, a significant area of sessile oak woodland. This woodland is designated as a Nature Reserve and is recognized for its biodiversity, hosting various mosses, ferns, and lichens, as well as providing a habitat for native Irish wildlife such as the pine marten and various bird species. The wood is considered one of the most important remnants of ancient woodland in the west of Ireland.
Mountaineering
Derryclare is a prominent feature for hillwalking and mountaineering in Ireland. It is most frequently climbed as part of the "Glencoaghan Horseshoe," a 16-kilometer loop that traverses several peaks of the Twelve Bens. The ascent from the southeastern side is noted for its sustained incline and rocky terrain, offering views of the Inagh Valley and the Maumturks mountain range to the east.
Hydrology
The mountain is bounded to the east by Derryclare Lough, a freshwater lake that forms part of the Ballynahinch catchment system. The lake and the rivers flowing from the mountain slopes are significant for salmon and sea trout populations, contributing to the local regional ecology and history of recreational angling in Connemara.
