South Wales (Welsh:De Cymru) is the region ofWales located nearEngland and theBristol Channel to the east and south, andMid Wales andWest Wales to the north and west. The most densely populated region in the southwest of theUnited Kingdom. It has a population of about 2.2 million people.[1] TheBrecon Beaconsnational park covers about a third of South Wales. The park also containsPen y Fan, the highest mountain south ofSnowdonia.
The region's boundary is not specifically known. It is considered thatGlamorgan,Monmouthshire,Carmarthenshire andPembrokeshire are a part of it. By the west, fromSwansea westwards, local people would probably say that they lived in both South Wales andWest Wales because of the overlap in the artificial boundaries.
