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.

Beaumaris Castle (/bjuːˈmærɪs/ bew-MAR-is; Welsh: Castell Biwmares Welsh pronunciation: [kastɛɬ bɪuˈmaːrɛs]), in Beaumaris, Anglesey, was built as part of Edward I's campaign to conquer north Wales after 1282. Plans were probably first made to construct the castle in 1284, but this was delayed due to lack of funds and work only began in 1295 following the Madog ap Llywelyn uprising. A substantial workforce was employed in the initial years under the direction of James of St George. Edward's invasion of Scotland soon diverted funding from the project, however, and work stopped, only recommencing after an invasion scare in 1306. When work finally ceased around 1330 a total of £15,000 had been spent, a huge sum for the period, but the castle remained incomplete.

The old suspension bridge is definitely the more scenic way to enter Anglesey than the main bridge that carries the A55.
