February 21, 2026, Llyn Cefni Reservoir and Dam

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.

Cefni Forest on Anglesey surrounds Llyn Cefni reservoir near Llangefni. It offers peaceful woodland trails for walking and cycling, linking to the Lon Las Cefni route. The forest is a sanctuary for red squirrels and diverse birdlife, making it a perfect spot for quiet nature exploration and wildlife watching.

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

Pont Marquis Bridge Spanning the Afon Cefni, carrying the Trefdraeth to Llangaffo road, c. 3km ENE of Malltraeth. The bridge, which is Grade II listed, was built in the early C19, was named for the Earl of Uxbridge, first Marquis of Anglesey. It gives wonderful scenery over the marsh land and plenty of wildlife.

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.
