The South Wales Valleys (Welsh: Cymoedd De Cymru) are a number of industrialised valleys in South Wales. Commonly referred to locally as "the Valleys", they stretch from eastern Carmarthenshire in the west to western Monmouthshire in the east and from the Heads of the Valleys in the north to the lower-lying, pastoral country of the Vale of Glamorgan and the coastal plain around Swansea Bay, Bridgend, the capital Cardiff, and Newport. Many of the valleys run roughly parallel to each other. The Rhondda Valleys and the Cynon Valley are located roughly in the centre.
