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)

Nantle Valley is well known for its mountains and ridge. A lot of historic settlements and slate mining. Stunning views of Snowdonia. Road surface is good watch out for sheep moving freely and a couple of cattle grids in this area

A nice section of forest path in amongst gorgeous woodland. It gets a tad narrow in places but a very nice bike section.
