Visitors to North Wales this summer are being encouraged to explore the area on bike after a new map outlining the National Cycle Network was published by the sustainable transport charity, Sustrans.

The 137-mile (220.5km) Lôn Las Cymru North challenge ride, which stretches between Holyhead on Anglesey and Llanidloes, Powys, covers a number traffic-free railway paths, minor roads, forestry tracks and ancient coach roads to provide cyclists with an environmentally-friendly means of visiting the region's landmarks.

As well as providing details of how to cover the entire distance of the route, the new Sustrans map offers information on individual options for a day ride, as well as the region's other walking and cycling paths.

Sustrans area manager for North Wales, Glyn Evans, said: "There are few other rides which offer such a variety of landscapes in such a short space of time, whether cyclists zip through it in three days or enjoy their surroundings at a more leisurely pace over the course of a week.

"The route is fully signed and easy to follow when combined with the new map, so riders will be able to devote all their effort tackling the odd steep hill or enjoy soaking up the views."
