At one time this countryside was wooded with hazel, elm and ash, but with the clearances for farming since the Stone Age, only a few patches of hazel now remain. The thin soils covering the grey limestone support a rich variety of grasses and herbs, like the pink thyme, blue harebell and yellow bird’s-foot trefoil. Managed by the Environment and Heritage Service (EHS), the Reserve is 0.75 miles (1.3km) west of the Marble Arch Show Caves gateway. From the information panel near the car park, follow the way-markers either clockwise or anticlockwise. Going clockwise, you will soon come upon a Bronze Age decorated stone and at about mid-point an Early Christian cashel or stone enclosure. The walk is over gently undulating landscape on grassy paths which thread through the Reserve’s limestone pavement and grassland, a ‘Karst’ landscape and habitat that is rare in Northern Ireland. Near the end of the walk, is McGrath’s traditional cottage, with a small interpretative display on local history.
