The village forms the westernmost fringe of the Amman valley and rests mainly on the anthracite coal measures, part of the South Wales coalfield. It straddles the A483 Swansea to Manchester Trunk road and has a linear village structure, having developed substantially along roads which meet at the centre of the village. The trunk road is in the main artery from north to south of the country and is connected to the M4 motorway network which affords transportation from mainland Europe to Ireland. The rail link at nearby Pantyffynnon contributes a daily service to Swansea, Llanelli and Shrewsbury.
