Aberfan is a former coalmining village in South Wales, south of Merthyr Tydfil Town. The Taff Trail (locally known as the "Canal Bank" or just "the bank") runs through Aberfan from Troed-y-rhiw, to Treharris. The River Taff also flows through Aberfan.
There are now two schools, Ynysowen Primary School adjacent to the Grove Field and Ysgol Gynradd Gymraeg Rhyd-Y-Grug which has moved to the previously occupied Ynysowen Primary School building.
The post office in the village is open six days a week.
