Carmarthenshire

Carmarthenshire lies in southwest Wales. Its county town, Carmarthen, sits on the River Towy, the longest river entirely in Wales, which winds east to west through the county and past market towns such as Llandeilo and Llandovery. The area includes upland moor and lowland farmland, with a long history of farming and rural trade. Medieval sites appear across the county: Carreg Cennen Castle sits on a limestone precipice near Trapp, and Kidwelly Castle guards an estuary entrance that once controlled local trade.

Coastal features include the sands of Cefn Sidan and the mudflats of the Burry Inlet, along which the Millennium Coastal Park and Llanelli town sit. Pembrey Country Park offers woodland and shoreline trails, and the National Botanic Garden of Wales at Llanarthne displays plants arranged across restored parkland. Former coal-mining communities in the Amman Valley and the historic wool trade around Carmarthen reflect industrial chapters that shaped roads and rail links still visible today.
