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.
