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.

Some great views here and it mostly gets you out of the prevailing SE wind. Watch out for tractors driven by 16 year old Lewis Hamilton wannabes! Get the tide right and you can ride along the beach at Dulas.

Mynydd Bodafon is a small collection of peaks including Yr Arwydd which is the highest point on the island of Anglesey. It lies about 2+1⁄2 miles west of the coastal town of Moelfre and ⅔ of a mile south-west of the hamlet of Brynrefail. The meaning of Bodafon is obscure. You can see the road below that you came in on to give you an idea of the height.
