Great loop around the reservoir, all kinds of gravel.

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
