Meini Hirion Penrhosfeilw

Standing stones don't get much more remote than this cluster on Anglesey's rugged coastline. Meini Hirion Penrhosfeilw - try saying that after a few pints - consists of several weathered granite pillars that have watched over this windswept corner of Wales for thousands of years. The stones aren't particularly tall or numerous, but their setting is what makes the visit worthwhile.

Getting there requires a proper walk across moorland from the nearest road, so this one's definitely for people who enjoy a bit of exercise with their archaeology. The path can be boggy after rain, and the Welsh weather being what it is, waterproofs are essential. History enthusiasts will appreciate the mystery - nobody knows exactly what these stones were for or when they were erected.

Children might find the trek a bit much, especially if they're expecting Stonehenge-style drama. What you get instead is a quietly atmospheric spot where you can contemplate ancient Wales without crowds of tourists snapping selfies.

From Holyhead, it's an easy drive to the area, making it a decent day trip if you're staying at one of the nearby holiday parks like Silver Bay Holiday Park or Sandy Beach Caravan Park. Allow half a day including the walk, and don't expect any facilities - this is ancient Wales in the raw.
