Hunsbury Hill

Iron Age earthworks crown this unassuming rise just south of Northampton, where you can walk the ancient ramparts that once defended a hilltop settlement 2,000 years ago. The archaeological remains are quite impressive - substantial banks and ditches that give you a proper sense of how these early Britons fortified their high ground.

Walking the perimeter takes about 20 minutes, though history enthusiasts will want longer to appreciate the defensive layout. The views across the Nene valley aren't spectacular, but there's something satisfying about standing where warriors once kept watch. Dog walkers use it regularly, and it's free to explore whenever you fancy.

Families with older children who don't mind a bit of historical context will find it interesting, though younger kids might get restless after half an hour unless they're into running up and down the ancient banks. The site connects to longer footpaths if you want to extend the walk.

From nearby holiday parks like Billing Aquadrome, it's a short drive that adds some historical depth to a Northamptonshire break. Not worth a special journey on its own, but if you're staying locally and appreciate ancient sites, it's a decent hour out. The lack of facilities means bringing your own refreshments, and the hilltop can be exposed on windy days.
