The seaside town of Criccieth has a long and interesting history. It is dominated by the remains of Criccieth Castle standing high above the sea on a craggy headland. The castle dates from the 1230s and played its part in wars between the Welsh and the English culminating in the rebellion of Owian Glyndwr. By contrast, the town of Porthmadog is of relatively modern origin. In 1810 William Alexander Madocks built a great embankment, the Cob, across the estuary of the Afon Glaslyn. The thriving port of Porthmadog sprang up, shipping vast amounts of slate from the nearby quarries. Between the two towns lie sandy beaches and low cliffs along which runs the Wales Coast Path, which we will follow from Porthmadog to Criccieth. We head from the harbour through Borth y Gest and over the low headland of Ynys Cyngar. Here out route heads down to walk along the wide, sandy beach of Black Rock Sands, which provides wonderful views across the estuary towards Harlech and the mountains. Leaving the beach, our path winds though fields and alongside the railway into Criccieth.
