in the Black Mountain The county is bounded to the north by
Ceredigion, to the east by
Powys (historic county
Brecknockshire),
Neath Port Talbot (historic county
Glamorgan) and
Swansea (also Glamorgan), to the south by the
Bristol Channel and to the west by
Pembrokeshire. Much of the county is upland and hilly. The
Black Mountain range dominates the east of the county, with the lower foothills of the
Cambrian Mountains to the north across the valley of the
River Towy. The south coast contains many fishing villages and sandy beaches. The highest point (
county top) is the minor summit of
Fan Foel, height , which is a subsidiary top of the higher mountain of
Fan Brycheiniog, height (the higher summit, as its name suggests, is actually across the border in Brecknockshire/Powys). Carmarthenshire is the largest historic county by area in Wales. The county is drained by several important rivers which flow southwards into the
Bristol Channel, especially the River Towy, and its several tributaries, such as the
River Cothi. Other rivers include the
Loughor (which forms the eastern boundary with
Glamorgan), the
River Gwendraeth and the
River Taf. The
River Teifi forms much of the border between Carmarthenshire and Ceredigion, and there are a number of towns in the Teifi Valley which have communities living on either side of the river and hence in different counties. Carmarthenshire has a long coastline which is deeply cut by the estuaries of the Loughor in the east and the Gwendraeth, Tywi and Taf, which enter the sea on the east side of
Carmarthen Bay. The principal towns in the county are
Ammanford,
Burry Port,
Carmarthen,
Kidwelly,
Llanelli,
Llandeilo,
Newcastle Emlyn,
Llandovery,
St Clears, and
Whitland. The principal industries are agriculture, forestry, fishing and tourism. Although Llanelli is by far the largest town in the county, the county town remains Carmarthen, mainly due to its central location. The lowest bridge over the river is at Carmarthen, and the Towi Estuary cuts the southwesterly part of the county, including
Llansteffan and Laugharne, off from the more urban southeastern region. This area is also bypassed by the main communication routes into Pembrokeshire. A passenger ferry service used to connect
Ferryside with Llansteffan until the early part of the twentieth century. == Economy ==
