Mynydd Carn-y-cefn

Mynydd Carn-y-cefn is a mountain summit in South Wales that rises between Ebbw Vale and the Ebbw Fach valley, creating a prominent ridge across the landscape. Its slopes contain visible sandstone and coal seams that formed during ancient geological periods.

The mountain formed during the Carboniferous Period when sediments compacted into rock and enclosed coal seams. This geological wealth attracted mining activity for centuries, which became central to how communities developed across the surrounding valleys.

The area holds deep roots in coal mining culture, and walking here connects you to a landscape shaped by generations of local workers. The summit serves as a natural landmark that people in nearby villages still use to understand their geography and community.

Several footpaths lead to the summit, and the western side is accessible by a minor public road. Open access land allows walkers to explore freely, with choices between different route options depending on your fitness level.

The slopes display notable landslip formations, particularly visible above the village of Blaina where the ground has shifted noticeably. These active geological movements show that the landscape continues to change rather than remaining fixed.
