A very good path - good enough for cycling - from Bwlch Maesgwm to the road above Llanberis. It is a beautiful valley with a feeling a remoteness.

From the bridge you have a beautiful view of the rivers Colwyn and Glaslyn and their banks. The bridge stands over the river Colwyn, which flows into the river Glaslyn a little further on (at the footbridge).

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.

Very nice views taken whilst standing on the bridge crossing located just after the meeting of two rivers or streams called Afon Colwyn and Afon Glaslyn. The foundations of some of the houses are build around fast flowing water in a rocky area. It is a nice spot to stop and admire the views

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
