This superb cycle route takes you coast to mountain via some beautiful and dramatic landscapes. The journey starts from Port Penrhyn in Bangor, and takes you past the world’s largest slate quarry, Penrhyn Quarry in Bethesda, before continuing up the impressive Nant Ffrancon valley to reach Ogwen Cottage. Here you will find yourself in the heart of some of the most striking mountain scenery in Snowdonia. In good weather it is well worth walking up to the adjacent Cwm Idwal. This National Nature Reserve is both spectacular and atmospheric.
The route follows a former railway track to the village of Tregarth, and then involves mixed off road/on road sections up to Ogwen Cottage. That being said, the road sections are not particularly busy.
The gradient is fairly gentle at first but becomes steeper and more demanding during the second half of the route. If you do make it all the way to Ogwen Cottage a wonderful downhill glide on the return trip back down to the coast. Those short of time or simply wishing for a less challenging route can always turn back at Tregarth or Bethesda.
The route starts at Port Penrhyn near Bangor. The nearby Penrhyn Castle provides an interesting diversion, either before or after the ride. There is a museum here which houses collections of dolls, locomotives and stuffed animals.
NB. Work is currently being done to improve the route, taking it via Bethesda and eliminating some of the busier road sections.
