The Cuilcagh Anierin Uplands SAC encompasses a rugged upland landscape shared by Northern Ireland and the Republic of Ireland, known for its rich biodiversity, distinctive geology, and outstanding opportunities for hiking and nature observation.
The Cuilcagh Anierin Uplands Special Area of Conservation (SAC) stretches across the border between County Fermanagh in Northern Ireland and County Cavan in the Republic of Ireland. This upland region is dominated by the dramatic Cuilcagh Plateau, a large expanse of exposed limestone pavement interspersed with blanket bog, peatland, and heath habitats. The area is noted for its diverse ecosystems, including rare orchid species, carnivorous plants, and important bird populations such as hen harriers and peregrine falcons. Evidence of prehistoric human activity is scattered across the uplands, including ancient megalithic sites and field systems, adding historical intrigue to the natural splendor. One of the most popular features within the SAC is the Cuilcagh Boardwalk Trail, also known as the 'Stairway to Heaven,' which weaves across the boglands and limestone pavement up to Cuilcagh mountain summit, rewarding hikers with panoramic views over Lough Erne and beyond. Beyond hiking, the uplands support diverse flora and fauna, making the area a top destination for wildlife enthusiasts and photographers. Remote and tranquil, the SAC appeals to visitors looking for a wild, rugged landscape that showcases the unique interaction of geology and biodiversity, as well as cross-border cooperation in conservation. Protection under the SAC designation ensures the preservation of this sensitive environment and maintains public access to these iconic natural features.
