Abergwynfi is a village in the Welsh county borough of Neath Port Talbot, in the community of Gwynfi and Croeserw.
[2] Aber and Blaengwynfi are generally referred to as "The Cape" by residents of the two villages and the neighbouring few.
This term comes from when the villages were marketed as "The Cape of Good Hope" during the years when coal mining was very important to the valleys.
[2] Abergwynfi is located within the Afan Forest Park, which is a popular mountain bike centre.
It is northeast of the Afan Vally, and is surrounded by forested hills and farmland.
