Hiking

Embark on the Llanthony Priory and Hatterall Ridge loop, a moderate hike that takes you through the scenic Brecon Beacons. This route covers 5.6 miles (9.0 km) with an elevation gain of 1201 feet (366 metres), typically completed in about 2 hours and 55 minutes. You will climb from the historic Llanthony Priory up to Hatterall Ridge, where you can enjoy wide-open views across Herefordshire and the Black Mountains. Keep an eye out for wild ponies grazing on the ridge and birds of prey soaring overhead. The terrain can be wet and uneven in places, especially on the descent, so sturdy hiking boots are a good idea.

Your hike starts and finishes at Llanthony Priory, a convenient spot with facilities like toilets and a cafe or bar. It is wise to check the weather forecast before you go, as the ridge can be exposed to strong winds. Given the potentially muddy and uneven sections, especially on the way down, make sure you wear appropriate footwear. Starting earlier in the day allows plenty of time to enjoy the views and the priory itself.

This loop offers a chance to walk a significant portion of the ancient Offa's Dyke Path, adding a historical layer to your outdoor adventure. The route's climb to Hatterall Ridge provides a different perspective of the Black Mountains compared to other local trails. The combination of historical ruins and expansive ridge-top views makes this a distinctive option in the Brecon Beacons National Park.

Stone Shelter on Hatterrall Hill

Highlight • Mountain Hut

Perfect place to have lunch wonderful views you can see for miles. 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.

Llanthony Priory Ruins

Highlight • Historical Site

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!
