Y Werthyr Hillfort

Ancient earthworks crown this windswept hill above Cemaes Bay, where Iron Age tribes once surveyed the Anglesey coastline from their fortified settlement. Y Werthyr Hillfort may not look like much at first glance - just grassy humps and bumps to the untrained eye - but spend a bit of time here and the defensive ramparts start to make proper sense.

History buffs will love piecing together how this hilltop fortress would have dominated the surrounding landscape 2,000 years ago. The views alone explain why someone chose this spot - you can see for miles across the Irish Sea on a clear day. Families might find it a bit niche unless the kids are particularly keen on ancient history, though the walk up does burn off some energy.

Access appears to be free and unrestricted, which is typical for Anglesey's archaeological sites. Allow an hour to explore properly and soak up the atmosphere. Early morning or late afternoon visits work best when the light picks out the earthwork details and you're less likely to battle the coastal winds.

For those staying at nearby parks like Dronwy Caravan Park or Sandy Beach Caravan Park, it makes a decent cultural detour between beach days. Not exactly a headline attraction, but worth the short drive from Cemaes Bay if you appreciate stepping back through the centuries.
