Hartfield Square

Hartfield Square sits just inland from Pevensey, a proper working nature reserve where the focus is on habitat rather than facilities. You won't find a visitor centre or cafe here - this is conservation land first, tourism second.

The reserve protects a chunk of Sussex wetland, and depending on the season, you might spot lapwing, snipe, or redshank picking their way through the marshes. The walks are straightforward and flat, which is both good and slightly dull if you're after drama. It's the kind of place where patience pays off - hang about near the water at dawn and you'll see far more than if you rush through at midday.

Best for keen birdwatchers or anyone wanting a proper walk without much elevation. Families with young kids might find it a bit limited unless they're already into wildlife spotting. Allow 90 minutes to two hours if you're doing the full route and actually looking for birds, rather than just passing through.

If you're based at Normans Bay Camping and Caravanning Club Site - about 5.5 miles away - this works well as a morning detour before heading to the beach or the wider Sussex coast. It's free to visit, though you'll want binoculars and a decent field guide to get the most from it. Go in spring or autumn when migration season brings more variety to the marshes.
