Mountain Ash

About

Mountain Ash lies within the Cynon Valley, following the river of the same name. The ward itself is centred on the town's historic linear layout, with residential streets climbing the steep valley sides from the main commercial thoroughfare. This topography defines the area, with terraced housing characteristic of the South Wales Valleys built into the slopes. The community remains closely connected to its industrial past, with former colliery sites now largely repurposed.

A notable local feature is the Dare Valley Country Park, which offers extensive green space and walking trails on reclaimed land. The town's facilities, including leisure centres and libraries, serve as hubs for the surrounding villages. Public transport links follow the valley floor, connecting to larger towns. The area's social history is evident in its workingmen's institutes and the enduring strength of its community organisations.
