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)

We followed the river upstream through the Aberglaslyn pass. The narrow path along the river requires some skill. At certain points you have to be very careful, especially in rain or when the water is high. However, you walk through a narrow gorge of considerable beauty, with beautiful views of a sometimes very turbulent river, rapids etc. In short, a very beautiful area.

When booking with accredited providers, essential equipment such as wetsuits, helmets, and buoyancy aids are typically supplied.
