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.

This tranquil location on the eastern tip of Anglesey has remains spanning over 1,000 years. It was the site of a monastery dating back to the time of St. Seiriol, who is believed to have lived in about the 6th century. A holy well which survives may have its origins in this period. In the early 13th century the Celtic community was reorganized under the Augustinian Rule, and at this time the priory church was enlarged. This now serves as the parish church. The monastery at Penmon is reputed to have been founded by St Seiriol, a 6th-century holyman and friend of St Cybi. The monastery prospered and in the 10th century fine crosses were set up at its gates, but the Viking raids have destroyed all other evidence of this date. During the 12th century, revival under Gruffydd ap Cynan and Owain Gwynedd the abbey church was rebuilt, and it remains the finest and most complete example of a church of this period in Gwynedd. In the 13th century the Celtic monasteries were persuaded by Llywelyn ap Iorwerth to adopt a more regular rule, and Penmon eventually became an Augustinian priory with quite substantial conventual buildings. The priory survived the Edwardian conquest and expanded slightly, but was dissolved in 1538. The buildings passed into the hands of the Bulkeleys of Beaumaris, who enclosed much of the land as a deep park and built a fine dovecote. They also converted the prior's lodging into a rather attractive house. Throughout this time the priory church remained in use, as it does today

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

The Red Wharf Bay is excellent for birdwatching, especially at low tide when a vast expanse of mudflats attracts curlew, oystercatcher, redshank, and plover. In winter, brent geese can also be seen. Pentraeth Forest is a crucial habitat for red squirrels, and you might even spot otters in the river flowing into the bay. Cors Goch nature reserve is also known for its diverse wildlife.
Beyond the main attractions, Pentraeth holds several hidden gems. St. Mary's Church in the village center dates back to the 12th-14th centuries with medieval stonework.
