Woodlark

A Iron Age hill fort that rises unexpectedly from the Suffolk flatlands east of Saxmundham. You'll spot the ramparts from the road, though most people drive straight past without realizing what they're looking at. The earthworks form a proper defensive ring, and there's enough elevation to give actual views across the countryside rather than the endless horizons you get at sea level.

It's free to explore, which is just as well since there's no visitor centre or facilities. Bring sensible shoes - the ground gets boggy depending on the season, and the banks are steep enough that you'll work for your vantage point. Allow half an hour to walk the perimeter and catch your breath at the top.

History buffs will appreciate this one more than casual visitors. The fort dates back around 2,000 years, and while there's not much left beyond the earthworks themselves, standing here makes you think about Iron Age communities in a way no museum placard quite manages. Kids might find it a bit underwhelming unless they're into fort-building generally.

If you're camping at Mill Hill Farm Caravan & Campsite just down the road, it's worth a quick detour on a morning walk before heading to the coast proper. Don't expect dramatic views or dramatic anything, really - it's a quiet, working slice of Suffolk archaeology that rewards a bit of curiosity more than it rewards Instagram followers.
