Route Description

Starting at the wonderfully located village of Malltraeth, in the south west corner of the island, the route heads along Malltraeth Marsh to Pont Marquis where the traffic free path starts. This section of the route is almost 3 miles long in a dead straight line, so beware when the wind is against you!

After crossing over the A5 and under the A55 trunk road, the route crosses the disused Amlwch Branch railway line before heading into Llangefni alongside the River Cefni. There are plenty of places to eat and fill up on supplies in this old market town before continuing the ride northwards.

The route leads you into the local nature reserve known as The Dingle which has additional boardwalks and sculptures to enhance the journey. Passing under the Amlwch Branch line you then ride above the River Cefni on an impressive boardwalk before you reach the shores of Llyn Cefni, a reservoir and local nature reserve. At the dam of the reservoir you can cycle eastwards to link up to National Route 5 or head west to finish at the village of Bodffordd.

From Malltraeth it is possible to travel in the opposite direction across Malltraeth Cob to Newborough Forest. Lon Las Cefni runs through the forest, famous for its red squirrel population, to the village of Newborough, or you can park up your bike and head to the beach at Newborough Sands.
