About

Gorllewin Porthmadog ward encompasses the western part of the town of Porthmadog and its immediate surrounding area. The ward is defined by its coastal position at the mouth of the Glaslyn estuary, with views across the water to the Cob causeway and the mountains of Eryri. The layout includes the historic harbour area and residential streets extending inland. This is a primarily Welsh-speaking community with a focus on local services and small-scale tourism linked to its maritime history.

The area's character is shaped by its industrial heritage as a former slate port, evident in the architecture of the old harbour and warehouses. The Ffestiniog & Welsh Highland Railways have their main terminus here, with steam trains departing regularly into the surrounding landscape. Natural features include the expansive sands of Traeth Bach and the protected saltmarsh environments along the estuary edges. The ward functions as a residential and commercial centre for the wider locality.
