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.

Surprisingly this is a two lane road and the amount of A roads around it means it was dead quiet even at peak school run time. But yeah it's a bit of a beast. Caught me out even after I'd ditched the luggage at camp. Would be a serious hill anywhere in England.

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.
