About

The Lôn Las Cymru (NCN Route 8) from Cardiff to Holyhead on through the Brecon Beacons, the Cambrian Mountains, and around the edge of Snowdonia is approximately 380km over four days, climbing around 1,000m per day.

Lôn Las Cymru Cycle Route: Rhayader to Llangurig Section: 11 miles one way, 22 miles return

Although this is not strictly a traffic free route, this minor gated road running down the Wye Valley carries next to no traffic as the main A470 runs parallel, on the other side of the valley, all the way from Llangurig to Rhayader. There is a .5 mile section on the slightly busier B4518 at the Rhayader end.

Start & Parking - Tarmac. Although the road follows the Wye Valley there are several gentle hills and the occasional steeper push. The river drops almost 250ft from Llangurig to Rhayader.
