About

Trimsaran is a community ward located in the Llanelli Rural area of Carmarthenshire. It lies near the Gwendraeth Valley, with its landscape characterised by former mining operations and reclaimed land. The area's history is closely tied to the local coal industry, which shaped its development for much of the 20th century. Residential areas are situated alongside green spaces that have regenerated over time.

The ward includes the village of Trimsaran itself, which serves as a residential hub with local services and community facilities. A notable local feature is the large Trimsaran Mountain, a prominent man-made hill created from colliery spoil, now covered in grass and used for walking. The area provides views towards the nearby coast and is traversed by roads connecting it to Kidwelly and Llanelli.
