Tips from the Community
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

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.
