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)

Porthmadog came about after William Madocks (a guess this is where the name of the town derives from) built a sea wall, the Cob to reclaim land from the sea for farming use. The diversion of the river caused it to scour out a new natural harbour deep enough for small ships and the first public wharves appeared in 1825. Quarry companies followed, with wharves along the shore mainly for the transport of slate and due to this the town grew in population and importance.

You'll probably be too gassed to look out for it, about 2/3rds the way up to the top of Cwm Penmachno from Lan Ffestiniog, so a good indicator of how far you've come.

Car park gets full up top so park sensibly park close to next car gives more space for others. Don’t park in front of gate as this is used by farmer Go Below and mountain/cave rescue. More parking available at bottom of hill.

Small train station in the mountains - slate was once mined here - now a tourist attraction.

Use the cycle track next to the con, not the road as cars tend to speed.
