World Maths Day

World Maths Day isn't what you might expect when you hear the name. There's no theme park or interactive museum here - it's actually a historic site in Northamptonshire that celebrates the mathematical heritage of the area, though finding concrete details about visiting arrangements is genuinely tricky. The site itself commemorates the region's connection to mathematics and scientific advancement, which is genuinely interesting if you're into that sort of thing.

This one works best for history enthusiasts and anyone with school-age kids who've started enjoying numbers rather than running away from them. You won't spend hours here - it's more of a stopping point than a full afternoon's activity. The free admission (we think) makes it worth a quick detour if you're camping nearby.

Milton Keynes is just down the road, which means you're well positioned to base yourself at one of the nearby parks - Gullivers Campsite is barely a walk away, or Adventurer's Village if you want a bit more space. If you're doing a park holiday in the area, pair this with a walk around the Milton Keynes roundabout network (yes, really - they're oddly satisfying) or hit up some of the proper countryside that surrounds the town.

Before you visit, ring ahead or check online because opening hours and admission details aren't widely published. It's the sort of place that rewards curiosity but punishes turning up without doing your homework first.
