The Slieve Tooey Mountains Special Area of Conservation protects a remote and rugged mountainous landscape in northwest County Donegal, offering rich biodiversity and pristine habitats for nature enthusiasts and hikers.
The Slieve Tooey Mountains Special Area of Conservation (SAC) is located on the Derryveagh Peninsula in northwest County Donegal, Ireland. This protected area encompasses a rugged, largely unspoiled mountainous landscape characterized by steep slopes, boglands, heath, and upland grasslands. The mountains reach elevations around 500-600 meters, with Slieve Tooey being a key peak within the area. The SAC was designated under the European Union Habitats Directive to protect rare upland habitats such as blanket bog, dry heath, and montane grassland, as well as important species including the hen harrier, peregrine falcon, and red grouse. The isolation and limited public access have helped maintain the area's natural condition, making it a vital refuge for upland flora and fauna.
Historically, the mountains have supported traditional sheep grazing and peat harvesting, but the landscape remains largely wild and untamed. Recreational opportunities include hillwalking and birdwatching, although formal trail infrastructure is minimal, preserving the remote wilderness experience. Hikers to Slieve Tooey can enjoy panoramic views of nearby Lough Mourne, the Bluestack Mountains, and in clear weather, glimpses of the Atlantic coast. The area is especially appealing to those seeking solitude, challenging terrain, and a chance to observe rare upland ecosystems in one of Ireland's most scenic but lesser-known mountain ranges.
