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.

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

Porthmadog is simply a busy hub, a gateway to the Llyn Peninsula and Snowdonia National Park. It is a lovely harbour town with a gorgeous mountain backdrop. It also has a good range of shops and attractions including nearby Portmeirion, a narrow-gauge railway, a normal railway and guess what...an excellent hands-on railway museum!

Criccieth Castle overlooks Tremadog Bay on the Llŷn Peninsula in North Wales. It was built in the 13th century and remains in remarkably good condition. It's well worth looking inside, although there is a charge, and you can learn about its history from boards. As you might expect, it's blessed with absolutely fantastic views.

Porhmadog is set on the Glaslyn estuary on the very edge of Snowdonia National Park. It is simply the gateway to one of the most incredible and beautiful parts of the UK. The town’s stunning seaside setting is the ideal base to discover spectacular surrounding mountain and coastal vistas on your bike. The views from Porthmadog marina and harbour are particularly gorgeous. The sublime outline of the nearby bulk of Moel y Gest and the obvious tranquil sea views make for a great setting to drop your heartbeat down a notch or two. You simply could not have a better place for a break off the bike.
