context_page_description: Waun Lefrith is a top of Picws Du and is also the westernmost of the Carmarthen Fans or Bannau Sir Gaer, a group of peaks within the Black Mountain of the Brecon Beacons National Park. It lies within Carmarthenshire, Wales. The summit plateau of the mountain reaches a height of 2221 feet above sea level. Picws Du and Fan Foel are the other, higher summits of the Bannau Sir Gaer / Carmarthen Fans. The glacial lake of Llyn y Fan Fach dominates the panorama to the north of the peak. Beyond the lake to the north lies the Usk Reservoir and then the Cambrian Mountains on the horizon. Swansea Bay and the Bristol Channel are visible to the south across the undulating dip slope of the mountain. The Tywi valley lies to the west, with Llandovery and Llandeilo as important market towns nearest to the hills.
context_section_description: The entire mountain is open country and so freely accessible to walkers. The most popular path of ascent is that from the car park at the foot of the water board road running steeply up to Llyn y Fan Fach and over which lake the mountain looms. It lies to the east of the small village of Llanddeusant. However, the road is in very bad condition for car travel, and poorly signposted. The ridge running up to the peak starts at the dam on the lake (where there is a small refuge hut or bothy) and rises west up the hill before turning along the edge of the cliff above the lake. The walk along the escarpment gives excellent aerial views of the lake, although some care is needed in poor visibility or cold weather.
  The high level route of the Beacons Way from Llangadog to Abergavenny runs over Waun Lefrith whilst the low level route runs along the foot of its northern escarpment to the small glacial lake of Llyn y Fan Fach. Most of the upper part of the mountain is covered with peat bogs, but the footpath is protected at some points by stone pavements. The path follows the edge of the escarpment, giving panoramic views in all directions. The footpath from Llanddeusant avoids the parallel tarmacked road to the dam, rising along the ridge which leads directly to the summit.
  As in all mountains care is needed when the weather is poor, when visibility falls due to mist, fog or driving rain and snow. Navigation can become difficult when landmarks disappear, and especially dangerous when walking along the edge of the escarpment. A prismatic compass and local map are essential companions to aid route finding. There are relatively few walkers on the Black Mountain, even when the weather is good and clear, so the walker must rely on his or her own resources to complete a circuit.
