September 21, 2025, Porthmadog Harbour

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.

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.

Gravel no longer, smooth tarmac all the way.

Just sublime when sunny, and even if not, the kind of narrow lane where you can ride along nice and relaxed.

No haute cuisine, but coffee and delicious cakes and rustic soups and other dishes. Very good after the strenuous hike.
