Start at the North Dock public car park beside St. Elli's Bay and the Discovery Centre. Take the Millennium Coastal Path east across the River Lliedi near the old tidal dock entrance, then follow the shoreline south towards Machynys. Stay on the shared coastal path as it curves around the southern tip of Machynys Point, with views across the Loughor estuary towards the north Gower coast and Whiteford Burrows.
Continue around the outside of the golf course, turning north and then east on the waymarked coastal path. Follow it to the public approach to Llanelli Wetland Centre, where the path meets the centre access. This is the turnaround. Retrace the same shoreline route via Machynys Point and the Lliedi crossing to North Dock. The walk remains on the established landward shared path; no beach or saltmarsh crossing is needed.
Allow around three and a half hours, with time for brief stops. The route is mainly level, surfaced walking and cycling path with gentle slopes. It is open to wind and rain, with limited shelter on the peninsula. Watch for cyclists and keep clear of the golf course and reserve-only paths. Carry water and use the landward route even when the foreshore looks inviting.
North Dock is council pay-and-display short-stay parking, with a four-hour maximum: check the current signs and leave enough time to return. St. Elli's Bay has refreshments and toilets during opening hours. The Wetland Centre is a separate optional visit, with admission to the reserve and seasonal opening days. It currently closes on Tuesdays and Wednesdays during September and October, apart from half-term; check WWT before relying on its cafe or toilets. Dogs are not allowed inside the centre except trained assistance dogs.
