Did You Know?
- •The hill is a prominent part of the Pennant Sandstone plateau, a geology that defines much of the rugged upland landscape across the South Wales coalfield.
- •Historically, the area formed a high-altitude boundary between the Afan and Rhondda valleys, serving as rugged grazing land while the valleys below were industrialised.
- •It now sits within the footprint of the Pen y Cymoedd wind farm, which generates enough electricity to power about 15% of the homes in Wales.
- •The surrounding forest tracks are part of the Afan Forest Park, meaning you are more likely to encounter a mountain biker than a fellow walker.
- •The ground is famously 'enthusiastic' at holding water; you haven't truly experienced this fell until you've been thigh-deep in a hidden bog that appeared perfectly solid ten seconds earlier.
