South Wales
South Wales is a region rich in natural resources. Beautiful valleys which once saw the growth of some of Britain’s greatest industries, offer visitors magnificent scenery and glimpses of the past. Much of the outstanding natural beauty of the area remains untouched. It is a land of contrasts, mountains and moorlands, forest and farmland and magnificent stretches of unspoilt coastline. The National Trust's interests in South Wales include large areas of the Brecon Beacons, Pembrokeshire and Gower, as well as the Dolaucothi Gold Mines and the Tudor Merchant's House in Tenby.

Cwmdu
Rhyd-yr-Onnen ('ford of the ash tree') is the official name for the late Georgian terrace of cottages, post office shop and inn at Cwmdu in rural Carmarthenshire. From 1837 to 1984, the terrace had been in the hands of one family until the last owner, Miss Annie Griffiths, who ran the inn and shop until she was 94 years of age. The National Trust bought the terrace after a period when it had been unoccupied and restored it and in 1994 the post office and inn were re-opened to serve the local community supported by the income from the 3 holiday cottages.
