About

St Clears is situated at the tidal limit of the River Tâf, historically functioning as an inland port and market town. Its layout centres on a main street with traditional commercial premises, reflecting its ongoing role as a local service hub for surrounding rural communities. The area maintains connections to the A40 road, linking it to broader transport networks across the county.

The ward extends to include Llansteffan, a coastal village dominated by the substantial ruins of a Norman castle overlooking the Tâf estuary. The village has a distinct linear character following the shoreline, with access to a large sandy beach. This estuary setting supports significant areas of saltmarsh and mudflats, which are important for local wildlife and landscape character.
