Afon Glaslyn

Glaslyn Gorge

The Afon Glaslyn (English, River Glaslyn) is a river in Gwynedd, north-west Wales. While not of great significance in terms of its length (about 16 miles (26 km)), it is one of Gwynedd's primary rivers, and has greatly influenced the landscape in which it flows.

It has its source in Snowdonian scenery.

The river emerges from the gorge into the relatively flat agricultural land of Tremadog and Porthmadog. This wide flat valley – now called Traeth Mawr – was once the estuary of the Glaslyn before the Porthmadog Cob was created. This sealed off the mouth of the estuary enabling the land to be reclaimed. Once the river has crossed under the railway line, it meanders in large pools and marshes before eventually passing through the tidal sluices on the Cob at the south-eastern end of the town of Porthmadog, and from there into Tremadog Bay. Further south, the River Dwyryd also drains into Tremadog Bay.

The first pair of breeding ospreys in Wales nest at Pont Croesor about 4 miles (6.4 km) upstream from Porthmadog where the RSPB have set up observation facilities. They first bred in 2005 and have returned every year since.

Fishing on the Glaslyn up to Beddgelert is controlled by the Glaslyn Angling Association.
