Lon Las Ogwen

The Lon Las Ogwen is the first section of the National Cycle Network’s route 82 that runs from Bangor in North Wales and enters the Snowdonia National Park at Bethesda.

It mainly follows the route of the old railway line that brought slate down the valley from the Bethesda slate quarry to the coast, where it was shipped around the world. The route is well sign posted with blue National Cycle Route signs.

The distance from Bangor to Idwal Cottage is 18km (11 miles) making it a great day trip, but note the Lon Las Ogwen can be completed in sections.

The new tunnel section of the Lon Las Ogwen is now open, making it possible to complete with route avoiding most main road sections.

The Trail is on the Guardian's list of "Five of the best scenic bike rides in Wales" and with the new tunnel section, it won’t be long before the Lon Las Ogwen will get labeled as one of the finest cycle trails in North Wales. It will surely feature highly on many a visitor to the area’s “must do list”!

It’s certainly one of my favourite rides, suitable for all riding abilities. The Lon Las Ogwen runs from the coast and mainly follows the valley floor, passing through some stunning mountain scenery on the way to Llyn Ogwen at Idwal Cottage. It provides a glimpse in the rich geological, industrial & social history that shaped the Ogwen Valley.

Please ride considerately on the Lon Las Ogwen. It is also used by dog walkers, runners & horse riders - so please slow down when passing other Trail users.
