About

The ward encompasses the compact village of Crynant, the former mining community of Onllwyn, and the larger settlement of Seven Sisters. The landscape is dominated by the rugged slopes of the Dulais Valley, with forestry and former industrial sites shaping the terrain. Residential areas are concentrated along the valley floor, connected by the A4109 road. The local economy has historically been linked to coal, with visible reminders in the surrounding hills.

A notable landmark is the large, modern rugby club and ground in Crynant, a focal point for community activity. The area is bordered by extensive forestry plantations to the north and east, including parts of the Brecon Beacons National Park. The River Dulais flows through the ward, and the landscape is marked by tips and old workings from the area's industrial past.
