Tips from the Community

Dominiek Van Dooren
May 7, 2026, Pont Aberglaslyn

The bridge was probably built in the 17th century and then radically rebuilt and widened in 1795-1796. As with many older bridges, folk tales claimed that the bridge was built by the devil or by the Romans (which an investigation by the National Trust described as "very doubtful"). During the reconstruction, a stone was found with the inscription "W M 1656" scratched on it, suggesting that the bridge is at least that old. Pont Aberglaslyn is located near the downstream end of the Aberglaslyn Pass. Although the location is rocky and the river flows through rapids upstream, it is not far above sea level. (Wikipedia)

There are many, many ways up Yr Wyddfa (Snowdon), though the Watkin Path is one of the six trails officially recognised by the national park authority. It's a quieter option than the routes from Llanberis and Pen y Pass and also one of the most strenuous. It was also the first public footpath in the UK when it was inaugurated in 1892 by Prime Minister William Gladstone.

Beddgelert is a lovely village below Moel Hebog, and the bridge over the river is a key feature.
