Summit specific forecast
Mountain summit forecast map
The Mourne Mountains are a granite mountain range in County Down in the southeast of Northern Ireland, is an area of outstanding natural beauty, and has been proposed as the first National Park in Northern Ireland.
The Mourne Mountains include the highest mountains in Northern Ireland; the highest of these is Slieve Donard standing at 850 metres at the northeastern edge of the Mournes, overlooking Newcastle and Dundrum Bay. At the summit of Slieve Donard there is a cairn and a small stone tower, which is part of the Mourne Wall, which passes over the mountain’s southern and western shoulders.
The Mourne Wall is a 35 kilometre dry stone wall that crosses fifteen summits, constructed between 1904 and 1922 by the Belfast Water Commissioners to define and enclose the catchment area for the newly constructed Silent Valley Reservoir.v
