Pont Marquis Bridge Spanning the Afon Cefni, carrying the Trefdraeth to Llangaffo road, c. 3km ENE of Malltraeth. The bridge, which is Grade II listed, was built in the early C19, was named for the Earl of Uxbridge, first Marquis of Anglesey. It gives wonderful scenery over the marsh land and plenty of wildlife.

Malltraeth Cob Malltraeth is the next village along from Newborough to the north. The two villages are linked by a “cob” – a dike wall – with a footpath/cycle track along its top. The cob was completed in the early 19th Century, under the direction of Thomas Telford and John Rennie. At the same time, the Afon Cefni was straightened (and straitened) creating what looks like a canal, but is still tidal. This created nearly 1,600ha of grazing land on either side of the Cefni. Much of this land is now a nature reserve managed by the RSPB. Also you will see Llyn Parc Mawr Community Woodland where they have picnic areas where you can enjoyed the red squirrels. It is off road but I used my gatorskins and it was fine.
