Pen y Fan is the highest peak in South Wales, reaching an elevation of 886 meters above sea level. It serves as the primary summit of the Brecon Beacons National Park. The peak is characterized by its distinctively flat-topped sandstone summit, a result of glacial erosion during the last Ice Age. It is located within the Central Beacons range and is managed by the National Trust. The site is a popular destination for hikers due to its accessible trails and panoramic views across the Welsh landscape. The terrain consists largely of Old Red Sandstone, which contributes to the mountain's weathered appearance.
