Carmarthenshire is a unitary authority in the south-west of Wales and is the largest of the thirteen historic counties of Wales. The three largest towns are Llanelli, Carmarthen and Ammanford. Carmarthen is the county town and administrative centre of Carmarthenshire, but the most populous settlement is Llanelli.
Although Carmarthenshire is less frequented as a tourist destination than some other counties in Wales, it offers a wide range of outdoor activities. Much of the coast is fairly flat; it includes the Millennium Coastal Park, which extends for ten miles to the west of Llanelli; the National Wetlands Centre; a championship golf course; and the harbours of Burry Port and Pembrey. Further west are the sandy beaches at Llansteffan and Pendine, and Dylan Thomas' boathouse at Laugharne. Further inland there are a number of medieval castles, hillforts and standing stones.
