Picws Du, or Bannau Sir Gaer, is the highest point of the dramatic escarpment high above Llyn y Fan Fach. Due to the remote and untouched landscape, you may have the opportunity to see lots of birds, including red kite, common buzzard, kestrel, carrion crow, common raven and skylark.

Fan Hir

Highlight • Viewpoint

Fan Hir means long summit in English, which is an apt description for this rather indistinct, long-drawn-out ridge summit that is part of a broader escarpment feature that circumnavigates Llyn y Fan Fawr and Llyn y Fan Fach. It forms the eastern ramparts of the Black Mountain, and its east face is extremely steep. The ridgeline it forms part of makes a great walk all the way back down south to Tafarn y Garreg.

Garn Goch is a 774-foot (236 m) hill above the village of Bethlehem in the far west of the Brecon Beacons National Park.

These are the largest hill fort remains in South Wales.

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.

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.

The views down onto Llyn Y Fawr from here is pretty spectacular. This is one of the nicest places in the Brecon Beacons to walk along. Once you have put in the effort to get here, the ridge has a good footpath, there's a nice walled shelter and the views down towards the lake is pretty awesome on a good day.
