Hatterrall Hill Summit

Highlight • Viewpoint

Hatterrall Hill – Mynydd Y Gader in Welsh – is a rounded high point towards the southern end of the Black Mountains' easternmost arm. Both the Offa's Dyke Path and Beacons Way pass its 1,742-foot (531 m) summit, which provides excellent views east into England and west, across the Black Mountains towards the Central Beacons. The ridge continues for many miles to the northwest, gaining height and eventually terminating on Hay Bluff.

Offa's Dyke Path

Highlight • Trail

Offa's Dyke (Welsh: Clawdd Offa) is a large linear earthwork that roughly follows the current border between England and Wales. The structure is named after Offa, the Anglo-Saxon king of Mercia from AD 757 until 796, who is traditionally believed to have ordered its construction. Although its precise original purpose is debated, it delineated the border between Anglian Mercia and the Welsh kingdom of Powys.

The earthwork, which was up to 65 feet (20 m) wide (including its flanking ditch) and 8 feet (2.4 m) high, traversed low ground, hills and rivers. Today it is protected as a scheduled monument. Some of its route is followed by the Offa's Dyke Path; a 176-mile (283 km) long-distance footpath that runs between Liverpool Bay in the north and the Severn Estuary in the south.

Although the Dyke has conventionally been dated to the Early Middle Ages of Anglo-Saxon England, research in recent decades – using techniques such as radioactive carbon dating – has challenged the conventional historiography and theories about the earthwork, and show that it was started in the early fifth century, during the sub-Roman period.

Twyn Llech (Black Mountain) Summit

Highlight • Viewpoint

Twyn Llech (703m), also known as Black Mountain, is the only Marilyn to fall exactly on the Welsh–English border, straddling Brecknockshire (Powys) and Herefordshire.

The Black Mountain is the highest point on the Hatterrall Ridge, with Offa's Dyke Path passing along the ridge.

Because of the very shallow gradients along the summit ridge it's virtually impossible to determine the actual high point by sight.

The ground is peaty and normally very wet even in good weather, especially on the highest ground.

Hay Bluff

Highlight • Viewpoint

This is a beautiful area and is popular with hikers, paracenders, bikers and the general population at large. There is a narrow single track road, with ample passing places, that passes over the common below Hay Bluff and it goes onto the famed viewpoint of the Gospel Pass. There's the main car park below the Bluff but there's also ample parking off the road in dry weather too. Super place for family picnics and walks.
