Glaslyn Estuary →Porthmadog is one of the most distinctive towns in Wales. Built in the early 19th century by the Anglo-Irish entrepreneur William Alexander Madocks, who dammed the Glaslyn estuary to reclaim thousands of acres of agricultural land, the town sits at the mouth of the Glaslyn and Dwyryd rivers where the mountains of Snowdonia sweep down to meet the tidal flats of Cardigan Bay.
The town owes its later prosperity to the slate trade. For much of the 19th century, Porthmadog was the busiest slate port in the world, shipping roofing slates quarried at Blaenau Ffestiniog to cities across Britain and Europe. The narrow-gauge Ffestiniog Railway was built to carry slate from quarry to port, and is now one of the world’s most celebrated heritage railways.
Today Porthmadog is perhaps best known to visitors as the starting point for two exceptional railway journeys — the Ffestiniog and the Welsh Highland — and as the nearest town to the extraordinary Portmeirion and the superb beach at Black Rock Sands. But the town rewards closer exploration: the harbour, the historic Cob embankment, the Glaslyn estuary and the surrounding countryside offer a visit of considerable depth.
Porthmadog is unique in Wales as the terminus of two narrow-gauge heritage railways, both departing from the Harbour Station on the High Street. The Ffestiniog Railway, opened in 1836 and restored by volunteers from the 1950s, climbs 700 feet through woodland, moorland and the outskirts of Snowdonia to reach Blaenau Ffestiniog in just under an hour. With steam locomotives, Victorian carriages and extraordinary scenery, it is one of the world’s great railway journeys.
Sharing the same station, the Welsh Highland Railway heads north through the mountains on a longer journey to Caernarfon, passing through the heart of Snowdonia. At over 25 miles, it is the longest heritage railway in Wales. Both railways can be combined in a single day using the Welsh Highland Heritage connection.
