Twmpa

The Gospel Pass (Welsh: Bwlch yr Efengyl) is the highest road pass in Wales. It is at the head of the Vale of Ewyas in the Black Mountains of southeast Wales. Starting from Hay-on-Wye the narrow mountain road climbs steeply to a height of 549 metres (1,801 ft) above sea level, squeezing between the mountains of Twmpa to the west and Hay Bluff to the east, before dropping down into the valley to the south on its way to Llanthony Priory, Llanfihangel Crucorney and Abergavenny. At one time a small lead-mining operation was established at the pass. The Gospel Pass is one of the most celebrated locations within the Brecon Beacons National Park, being a popular destination for sightseers and is popular too with walkers and cyclists. Indeed, the Gospel Pass road forms a part of route 42 of the National Cycle Network. It also featured in the opening scenes of the film "An American Werewolf In London". It is a single track road over most of its length, but there are numerous passing places. Owing to its height and exposure, it is occasionally blocked by snow during the winter. It is well used by walkers since it gives access to the major peaks of the Black Mountains, especially at the northern end of the road, where there are several car parks.

Hay Bluff (Welsh: Penybegwn) is a prominent hill at the northern tip of the Black Mountains, an extensive upland massif which straddles the border between south-east Wales and England. The mountain sits at the point where the main northeast-facing escarpment of the Black Mountains meets the northwest facing escarpment, the next peak to the west being Twmpa. The flat summit of Hay Bluff which is marked by a triangulation pillar at a height of 677 metres (2,221 ft) overlooks the middle Wye Valley and the book town of Hay-on-Wye. The hill is largely within the Welsh county of Powys though parts of its eastern flanks lie within the English county of Herefordshire.
