Cuilcagh Anierin SAC is a cross-border protected natural landscape known for its unique blanket bog habitats, diverse flora and fauna, and iconic mountain trails that attract nature lovers and hikers alike.
The Cuilcagh Anierin Special Area of Conservation (SAC) straddles the border between Northern Ireland and the Republic of Ireland, encompassing the Cuilcagh Mountain range and extensive blanket bog systems. Covering parts of counties Fermanagh, Cavan, and Leitrim, the SAC protects one of the most important mire ecosystems in these islands. The terrain is characterized by upland blanket bogs, heathlands, oligotrophic lakes, and wet grasslands, which provide habitats for several rare and protected species including the hen harrier, peregrine falcon, and rare mosses and lichens. Cuilcagh Mountain itself, rising to 665 meters, offers iconic trail experiences, most notably the Cuilcagh Boardwalk Trail (also known as the 'Stairway to Heaven'), which draws outdoor enthusiasts with its scenic views of Fermanagh Lakelands and surrounding countryside. The area’s ecological significance is complemented by its rich cultural heritage, with remnants of ancient dwellings, megalithic sites, and past land uses shaping the landscape. Visitors come for hiking, birdwatching, and to explore the unique peatland environment. Conservation efforts focus on preserving the sensitive bogs, controlling invasive species, and promoting sustainable tourism to ensure this natural treasure is maintained for future generations.
