May 3, 2026, Rhyd Ddu Railway Crossing

Stop, look out and listen are the recommendations (to be read on the sign) that you must follow when crossing the track here. It is an unguarded crossing on this railway for tourist trains.

Insanely steep at 37.45% early on but eases off quickly.

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.

Pont Scethin is a stone single arch bridge in a superbly wild and lonely setting in the Rhinog foothills. The bridge used to be on the old London to Harlech packhorse and drover route, and is probably 18th century. Source: https://coflein.gov.uk/en/site/24197/

Tis is the crossing of the Ffestiniog Welsh Highland Railway at Rhyd Ddu. once through the crossing the surface becomes compact gravel and climbing. It is rideable but takes effort
