Wilderness Landscape & Natural Heritage
The Mourne Mountains Special Area of Conservation (SAC) covers approximately 12,520 hectares in County Down, Northern Ireland. It includes the Mourne Mountains, a granite mountain range featuring the highest peaks in Northern Ireland, including Slieve Donard at 850 meters. The SAC designation reflects the area's importance for rare upland habitats and species. Notable habitats include heathland, blanket bog, and montane grassland that support a range of wildlife such as red grouse, peregrine falcon, and rare plant species like the Irish eyebright. The mountains form a dramatic landscape of rocky tors, steep slopes, and glacial valleys. The region is steeped in history, with ancient cairns and the iconic Mourne Wall built to enclose the catchment area for the Silent Valley Reservoir, an important water supply. Recreationally, the Mournes offer numerous hiking routes ranging from challenging summit ascents to gentle valley walks, attracting hillwalkers, climbers, and nature watchers. The area also hosts the Mourne Wall Challenge, a popular endurance walk. Visitor appeal includes panoramic views across the Irish Sea, opportunities for birdwatching, and the cultural heritage linked with the mountains. The SAC status ensures conservation measures that protect the landscape’s natural features while encouraging sustainable recreation.
