Carmarthen Bay

Carmarthen Bay (Welsh: Bae Caerfyrddin) is an inlet of the south Wales coast. The coastline includes notable beaches such as Pendine Sands and Cefn Sidan sands, and is partially within the Pembrokeshire Coast National Park. Wind turbines were tested here in the 1980s. Carmarthen Bay and Estuaries is listed as a Special Area of Conservation by the Joint Nature Conservation Committee

The River Loughor flows into the bay at the Loughor Estuary, and the rivers Towy, Taf and Gwendraeth flow into the bay at the Three Rivers Estuary. Caldey Island lies in the bay near Tenby. Towns and villages in the bay include from east to west, Llanellii, Burry Port, Pembrey, Kidwelly, Ferryside, Llansteffan, Laugharne, Pendine, Amroth, Wisemans Bridge, Saundersfoot and Tenby. There are fine beaches at Pendine Sands, Cefn Sidan, Laugharne, Llansteffan and Ferryside.

Carmarthen Bay and Estuaries is listed as a Special Area of Conservation by the Joint Nature Conservation Committee, a public body that advises the Welsh Government on international nature conservation. The area conserved includes sea inlets, tidal rivers, estuaries, mud flats, sand flats, lagoons (including saltwork basins), salt marshes, salt pastures, salt steppes, shingle, sea cliffs and islets. The sand and mud flats have large numbers of bivalve molluscs including the edible cockle. The large shallow inlets and bays provide habitat for a great variety of marine invertebrates. The saltmarshes have biodiverse communities of glasswort (Salicornis species), dwarf eelgrass (Zostera noltei), sea rush (Juncus maritimus) and marsh-mallow (Althaea officinalis) and all the wildlife they support. A primary reason for the listing is the presence in the bay of the twait shad (Alosa fallax), a migratory fish.
