Afon Cefni is one of the major rivers on the island of Anglesey, Wales. It is 16.9 kilometres long. Its source is near to the village of Capel Coch, before flowing through Bodffordd and into Llyn Cefni in the centre of the island. It continues to run south through the county town of Llangefni

RAF Mona Airfield

Highlight • Historical Site

This location was first used for aviation during the First World War when the Royal Naval Air Service opened an airship base here named Royal Naval Air Station (RNAS) Anglesey (also known as RNAS Bodffordd, RNAS Gwalchmai and RNAS Llangefni).

RNAS Anglesey was commissioned on 26 September 1915, when it was operated by 14 Group RNAS, operating SS18, an SS class airship, which was later joined by airships SS22, SS24 and SS25. The station had in a large airship hangar, 120 by 318 feet (37 m × 97 m) long, workshops, hydrogen gas production sheds and accommodation huts. The airships, which could drop bombs, escorted ships and patrolled for enemy submarines in the central section of the Irish Sea between Bardsey Island, Dublin, the Isle of Man and Morecambe Bay. This area includes the approaches to the Port of Liverpool, then one of the busiest ports in the world.

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.
