Offa's Dyke Path in Bannau Brycheiniog National Park

Highlight (Segment) • Historical Site

The first stage of the Beacons Way falls into two segments (of 1km and approx. 5km respectively) along with Offa's Dyke Path, one of those other long-distance walks (285km) in the west of England.
The name refers to King Offa who ruled Mercia in the 8th century. The causeway was supposed to mark the border between his Anglo-Saxon kingdom and the Welsh kingdom of Powys.

It is often about eight meters wide and is elevated about 2.5 m above the lakes / wetlands.

The path starts in the northern Bay of Liverpool and ends at the mouth of the Severn, to date the southernmost point of the border between Wales and England.

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.

Hatterall Hill Ascent and Descent

Highlight (Segment) • Trail

In fair weather the climb/descent of Hatterall Hill (1,742-foot summit) on Offa’s Dyke Path is a magnificent adventure. The route affords splendid and extensive panoramas over Monmouthshire (south and west), Powys (west) and Herefordshire (east). In addition, the path crosses the Pentwyn Iron Age Hill Fort and will usually encounter Welsh Mountain Ponies (classified as a rare breed). This walk is exhilarating and surprisingly easy, full of greenery and well worth the effort!
