Mynydd Machen

Mynydd Machen is a hilltop in Wales rising to 362 meters, with a distinctive survey point and transmitter mast crowning its peak. These structures mark the southeastern boundary of South Wales and are visible from surrounding areas.

The mountain was shaped during the Carboniferous Period with steeply tilted rock strata containing coal deposits. These mineral resources drove the industrial growth of South Wales over many generations.

The mountain acts as a meeting point for different walking routes, including the Rhymney Valley Ridgeway Walk, linking communities through paths that have been used for generations. These trails bring people together across the Welsh landscape in a shared experience.

The summit can be reached via several footpaths, with parking areas near the transmitter mast and along the approach road. Visitors should prepare for changing ground conditions and bring suitable weather gear.

The rock formations display northeast-southwest aligned bands, including the Warwickshire Group and Pennant Sandstone Formation, creating a natural study site. This geological arrangement reveals layers that tell the story of ancient environmental changes.
