Borth Wen

The Iron Age fort at Borth Wen sits on a hilltop overlooking the Anglesey coastline, and it's the kind of place that rewards the walk up. You're looking at the remains of a defensive settlement dating back around 2000 years - just earthen ramparts now, but they still command the landscape in a way that makes you understand why someone chose this spot. The views across the Menai Strait and toward Snowdonia are genuinely worth the trip, especially on a clear day.

It's not a manicured heritage site with interpretation boards and a visitor centre. Instead, you get the real thing - a bit rough around the edges, quiet, and honest. The walk takes about 15 minutes from the nearest access point, and it's gentle enough for families with older kids, though younger ones might find the climb tedious. History enthusiasts will appreciate standing where Roman-era inhabitants once looked out for threats from the sea.

The nearest town is Pentre, which is tiny, so you'll want to base yourself at one of the nearby caravan parks - Silver Bay Holiday Park sits just half a mile away and makes a logical jumping-off point. Combine this with a proper coastal walk along Anglesey's beaches, and you've got a solid half-day. Allow 90 minutes if you want to linger at the top. Free to visit, obviously, since it's just open moorland. Don't expect facilities, but do expect solitude and a genuine sense of place.
