About

North Blackwood, Argoed, and Markham form a cluster of former mining villages situated on the northwestern fringes of the Caerphilly county borough. The area is defined by its position on the steep, wooded slopes of the Sirhowy Valley. Terraced housing and local community facilities are arranged along the winding valley roads, with residential streets climbing the hillsides.

The landscape is heavily shaped by its industrial past, with former colliery sites now largely reclaimed by woodland. The area is traversed by the Sirhowy Valley Walk, a path following the route of a disused railway line that connects the communities. This green corridor provides a direct link through the wooded valley for walking and cycling.
