Map of the UK

Onllwyn sits in the steep, wooded folds of the Dulais Valley in Neath Port Talbot, South Wales. The village overlooks the valley and the River Dulais, and is a quiet, rural-leaning settlement with ready access to upland walking and cycling; the surrounding hills form part of the drumlin‑like landscape that leads towards the Brecon Beacons.

Historically Onllwyn was shaped by coal and iron‑working, and that industrial past still informs local identity through miners’ halls, chapels and strong community ties. Like many former pit villages it has weathered economic change and planning debates over land use, yet retains an active community life and interest in preserving its industrial heritage alongside new outdoor and conservation activities.
