Dominiek Van Dooren
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.

I think the start and the end is probably the hardest but overall pretty easy path you can’t get lost

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

Always handy to know a bike shop is within the area. Framed bikes is on the main street through Llanberis. The owner said there is a two to three week wait for work, but I got the feeling he would assist riders passing through

Llyn Cwellyn is a reservoir in North Wales which supplies drinking water to parts of Gwynedd and Anglesey. It lies on the Afon Gwyrfai in Nant y Betws between Moel Eilio and Mynydd Mawr in the northern part of Snowdonia National Park. It has an area of 215 acres, and is over 120 ft deep. It has amazing views well worth a stop.

Maesgwm is also known as Telegraph Valley. The trail is gravel and well-made, brilliant to ride and much quieter than the main Llanberis path. It makes a great loop from Llanberis, using a section of the Ranger. Rideable in both directions.
