Llyn Cefni Dam During World War II, a water scheme was devised for the town of Llangefni in central Anglesey. It involved water from a local source being pumped to two settling tanks in the Dingle part of the town. From here the water was pumped across the river to a reservoir and water tower, on the site of the present Pennant Estate. These arrangements became redundant with the building of the Cefni Reservoir, which was completed in 1951, but the settling tanks and pumping station survive in Llangefni to this day. The new scheme was designed to supply most of the water needs for the people of Anglesey for the foreseeable future

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.

Llangefni (meaning "church on the River Cefni", Welsh pronunciation: [ɬaŋˈɡɛvni]) population 5,116, making it the second-largest town in the county and the largest on the island. The community includes the village of Rhosmeirch. Wonderful welsh town with all the shop can get busy in summer holidays.

The largest town on Anglesey (Holyhead is twice the size but is technically on Holy Island). Now bypassed by the island’s main roads which actually makes it a decent hub if you’re cycling across the south of the island.

Nice cycle path along the embankment gives a great view of Malltraeth Sands as a more pleasant alternative to the A4080.

The path is fairly easy to miss if you’re coming along the A5: look for the section of railing by the roadside which marks the entrance. The path itself has some awkward narrow turns where it passes under the A55 but after that it’s wide, smooth and usually clear.
