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.
From the cob there are beautiful views in all directions. On the inland side, lie a series of pools, known as the Cob Pools, with the vast Malltraeth Marsh / Cors Ddyga beyond. To the seaward side are the Malltraeth Sands with Malltraeth Bay beyond. The whole area is a haven for wildlife, particularly birds.
At the Malltraeth end of the cob, there are several benches and a small picnic area (and a chip shop in the village). There are also information boards explaining the history of the cob and the geology of the area, as well as a visual guide to help you identify the mountain peaks that form the horizon to the south.
At the Newborough end of the cob, there is another small car parking area, with picnic benches, known as the Malltraeth car park.
The path on the cob is completely flat. From one end to the other it is about a mile long.
