Mynydd y Drum

Mynydd y Drum is a hill in South Wales standing at approximately 340 meters with a distinctive broad rounded ridge. The area is dominated by open grassland and sits along the boundary between Powys and Neath Port Talbot County Borough.

In the 19th century the Claypon's Tramroad ran along the hillside connecting industrial sites between Onllwyn and Ystalyfera. The area was part of the South Wales coal industry that shaped the entire region during that era.

The name comes from Welsh and means drum-shaped hill, reflecting how locals describe this rounded landform. The open moorland and grassland show how pastoral farming has shaped the landscape over centuries.

Several public footpaths and bridleways start from nearby villages like Abercraf and Ystradgynlais and head up toward the summit. The hill is accessible from multiple points, so you can choose your route depending on where you start your walk.

The eastern section contains an opencast coal mining operation extracting resources from sandstone and mudstone formations of the South Wales Coal Measures. This active industrial area shows the continuing economic importance of mining traditions in the region.
