Hatterrall Ridge
The Hatterrall Ridge (or Hatterall Ridge) is a long, straight, steep mountain ridge which is the easternmost outlier of the Black Mountains.[1] The ridge forms the boundary between Herefordshire in the east and Brecknockshire and Monmouthshire to the west.
The ridge is about 10 miles long, and the Offa's Dyke Path runs along the top of it. On the west side of the ridge is the Vale of Ewyas, and on the east side is the Olchon Valley. The western side of the ridge falls within the Brecon Beacons National Park.
The highest point on the ridge is Black Mountain (2,306 feet), near its northern end. Hatterrall Hill (1,742 feet) is near the southern end of the ridge. The hill is common land grazed by sheep, ponies and cattle.[2]
