Llanthony Priory is a partly ruined former Augustinian priory in the Black Mountains area of the Brecon Beacons National Park. As well as being a stunning place to visit it is a start point for many a hike and good stop point on a bike ride before or after doing the famed Gospel Pass (highest pass in Wales). It has a great little pub/tavern on site and nearby (between the priory and the road below) is a camp site if your back or bike packing. On a sunny day this is a heavenly place to be!

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.

View of Hatterrall Hill and the Black Mountains

Highlight • Viewpoint

Hatterrall Hill is a rounded peak in the Black Mountains which sits on the Wales-England border, partly in Monmouthshire, Wales and partly in Herefordshire, England. Its summit at 531m is the high point of a peaty plateau which falls away steeply on all sides. Broad ridges run to the north, the southeast and southwest. To the north the ridge (known as Hatterrall Ridge) dips to a col at around 485m elevation before rising gradually over several kilometres towards Crib y Garth / Black Hill and Hay Bluff. The ridge to the southwest ends abruptly at the sheer cliff known as the Darren below which is a considerable landslipped area extending south to the hamlet of Cwmyoy with its mis-shapen church. The Welsh part of the hill falls within the Brecon Beacons National Park.
