Slievenacloy Nature Reserve is a hidden retreat of species-rich grassland famous for its beautiful orchids in early summer.

Situated in the Belfast Hills, between Stoneyford and Divis Mountain, Slievenacloy Nature Reserve, owned and managed by Ulster Wildlife, is one of the best examples of a species-rich grassland in Northern Ireland.

Its name Sliabhna Cloiche means ‘townland of the stone’, most likely a sacred landscape during the Neolithic and Bronze Ages with eight prehistoric burial monument recorded. Towards the Stoneyford River is a mysterious earth ring.

The site contains the remains of an old farmhouse dating back to 1833.

To maintain Slievenacloy’s important habitats and special wildlife, the reserve is grazed with traditional livestock such as Irish moiled cattle from early summer to mid-winter.  Essential habitat management including rush cutting and scrub control is also carried out throughout the year.

Visitors are welcome to explore this special site on foot, all year round from dawn to dusk.  This vast wilderness of over 300 acres is a mosaic of natural meadows, purple moorgrass and rush pasture.  At various points there are breath-taking views across Belfast and five of the six counties of Northern Ireland.  There are old farm tracks throughout the site and some waymarked trails.
