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.

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.

The Lonely Tree was a Scots pine on a hill near Llanfyllin, Powys, Wales. Visible from much of the town it was a local landmark with several traditions attached to it. The tree was blown over during a storm in February 2014, and despite efforts to save it, the tree was found to be dead in June 2015..

Great views from the bridge at the western end of Llyn Padarn. Look across the lake at the old Dinorwig slate mining and the Electric Mountain. To the right you can see over Llanberis and up onto Snowdon.
