The 1,900 acre estate includes the largest surviving area of oak woodland in Northern Ireland and one of the most important and least spoilt freshwater habitats in the British Isles.
The wealth of wildlife at Crom is exemplified by the presence of two rare butterflies – the purple hair-streak and wood white, the elusive pine marten and the largest herony in Ireland.
There are many fine old buildings which enhance the landscape including the ruins of The Old Castle, Chrchton Tower and Crom Church. The 19th century castle is private and not open to the public.
A Visitor Centre houses an exhibition on the history and wildlife of the estate, lecture room, the Little Orchard Tea Room, a small shop, slipway and seven excellent self catering cottages. Boat hire and overnight bird and mammal watching hide can be arranged through the Visitor Centre. Day tickets for coarse fishing are available.
Crom Castle is within easy driving distance of two other National Trust properties in Fermanagh – Florence Court and Castle Coole.
