Millennium Coastal Path at Pembrey

The Millennium Coastal Path at Pembrey. This is part of National Cycle Network route 4 where it runs along the edge of the dunes at Pembrey at the western end of the Llanelli Millennium Coastal Park. The 22km long park was mostly reclaimed from industrial wasteland and otherwise useless waste products - 800,000 tons of pulverised fuel ash from the site of the Carmarthen Bay power station and sewage sludge and silt from Burry Port harbour - were used in the reclamation process.
