Dyffryn Clydach includes the residential communities of Cwrt Herbert, Dyffryn, Highlands, Longford, Neath Abbey, and Penshannel. It is located in the county borough of Neath Port Talbot, South Wales.

The more central and northerly parts of the ward are mostly rural, consisting of picturesque farmland and woodland encircling the western base of Drummau Mountain. With footpaths maintained by the community council, there are many excellent walks including through The Cwm where The Clydach Brook flows in a north to south direction.

There are two popular local schools: Neath Abbey Infants’ and Early Years School and Mynachlog Nedd Junior School. Dyffryn Clydach Memorial Hall is a bustling and recently refurbished community centre with two committee rooms, situated on The Drive, Longford. There is also a large playground suitable for children of all ages.

There is a thriving business park to the south of the community area with good A465 and M4 access.

Although covering only 7 km2 (2.7 sq mi), the area is packed with history, The ruined Cistercian monastery of Mynachlog Nedd, the Tennant Canal and the world famous 19th century Neath Abbey Ironworks are all within easy walking distance. The current Tesco store is believed to occupy the site of an 11th-century castle.

The Dyffryn Clydach Community Map Tapestry is the beautiful and unique result of a community project which took place over 18 months. Thanks to funding from Dyffryn Clydach Community Council and The Wales Assembly Government’s Rural Identity Fund , Cllr Alyson Thomas designed and supervised the project which involved over 70 weavers from all sectors of our community. The tapestry and its accompanying group panels was unveiled by the oldest participant Mrs Louisa Davies in May 2011 at a community celebration day. It is proudly and permanently display at the Dyffryn Clydach Memorial Hall.
