Picws Du, Mountain summit in Carmarthenshire, United Kingdom.
Picws Du is a mountain in Carmarthenshire with steep sandstone cliffs on its northern face that rise to 749 meters within the Brecon Beacons National Park. The landscape is defined by these dramatic rock formations that stand out against the wider moorland terrain.
The summit holds an unexcavated Bronze Age round barrow, indicating that people lived on these slopes during periods of warmer climate. This archaeological remnant shows that the mountain has long been part of human settlement and movement across the region.
The mountain sits near Llyn y Fan Fach lake, which links to Welsh folklore through the traditional story of the Lady of the Lake. This connection shapes how people experience and visit the area today.
You can reach the peak through several marked trails, with the most direct route beginning from the Llyn y Fan Fach car park. The paths are clear to follow, but weather can change quickly and affect visibility on the exposed slopes.
The mountain ranks as the second highest peak of the Carmarthen Fans and commands views across the Cambrian Mountains toward the Bristol Channel. From this elevation, clear days reveal the full scale of this Welsh mountain landscape.
