Warden Hill

The highest point in Lincolnshire isn't exactly Ben Nevis - Warden Hill tops out at 168 metres and sits just outside Horncastle, a market town that's worth a wander in its own right. You'll find yourself on gently rolling farmland rather than dramatic peaks, which is rather the point. It's a proper East Midlands sort of climb: achievable, pleasant, and the views across the Fens stretch out surprisingly far on a clear day.

Walkers after a straightforward leg-stretch should allow an hour or so for the ascent and a bit of mucking about at the top. The gradient's manageable enough for families with kids who don't fancy anything too taxing, though younger ones might lose interest once they realise there's no cafe at the summit. History buffs will note it's an Iron Age fort site, which adds a bit of weight to what might otherwise feel like a rather ordinary hill.

There's no admission charge - it's just open access. Come on a dry spell if you can; the Lincolnshire clay gets properly boggy when it's wet. If you're based at Lincolnshire Glamping or Oxcombe Campsite nearby, this makes for a decent morning activity before heading into Horncastle for lunch. It won't dominate your whole day, but it's the sort of thing that stops a park holiday feeling too sedentary. Worth the detour if you're in the area, less essential if you're making a special trip.
