We visited for the Parkrun, which was cancelled whilst a walkway is fixed (some more weeks, I would expect). You can still access the lake along the disused railway line for part of the way - but not a good surface for running. Then there is a path around the lake with views across the lake and stretches through the woods, lovely, if rather muddy in places following wet weather. In total about 9 km around. Hope to do this again in the Spring with the promise of wild daffodils and perhaps a red squirrel.

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.
