Tips from the Community

David Howells
February 4, 2024, Garreg Las Summit Cairns

Garreg Las (Twyn-Swnd) is on the west side of the Black Mountain range, and it is visited far less often than many peaks in the Brecon Beacons. Its remoteness is its draw for me; rarely will you be unindated with a host of other walkers here. It is also hansomely topped by a pair of substansive, rocky ancient cairns. You can come across from the car park on the A4069 Brynaman Road or come up from Llanddeusant; both are equally as appealing, but the Llanddeusant route takes the top slot if you go back via Llyn y Fan Fach; this route has the best views. The views from the summit itself are like the location: raw and remote, but I love the place. It is a good area for a bit of navigation practice. At 635 metres high, it is a UK-listed Nuttall and Hewitt. Tip: Any Welsh place name with Llan in it means it has a church. In this case, Llanddeusant means the church with two saints.

At just 440 metres Tair Carn Isaf is a modestly sized hill, but its prominence at the western end of the Black Mountain, high above the Amman Valley, affords extensive views over central south Wales, into Powys, west to the Preselis, and over the Gower Peninsula and Severn Estuary.

Garreg Lwyd, also known as Moel Gornach, is a peak in the Black Mountain of the Brecon Beacons, South Wales. It is a subsidiary summit of Fan Brycheiniog. It is the westernmost area over 2,000 feet above sea level in South Wales.

This is a very undervalued area of the western Brecon Beacons. The walking here is raw and wild, which is one of the reasons why it is also a quieter part of the park, so it will appeal to many. Here you also will find some of the best examples of Iron Age hillforts you can ever hope to see anywhere. Y Garn Goch and Y Gaer Fach are some of the most impressive hill forts in Wales. At 11.2 and 1.5 hectares, respectively, these are impressive structures and in their day provided considerable defensive structures to the native inhabitants. The large stone defensive ramparts, which are large rubble banks today, once stood 10m high and 5m thick. You can access both forts from a small car park at the base of the hill.

Easy summit to get too, not as challenging as the big peaks to the East - only a short walk from them too. Interesting terrain at the top - very rocky.
