Welham Grove Green

The wetland at Welham Grove Green sits just outside Retford and makes for a proper rewarding walk if you've got time to kill between campsites. It's a nature reserve rather than a manicured park - reed beds, open water, rough grassland - the kind of place where you might actually spot something interesting rather than just a tidy lawn.

Bring binoculars if you're into birds. Warblers, water rail, the occasional heron if you're lucky and quiet. In spring the whole thing comes alive with sound. Summer can be muggy and buggy, so either embrace it or time your visit for autumn when the light's better and you've got more elbow room.

It's a short walk to the reserve from Retford itself, so you won't need to drive far from Hallcroft Fishery or any of the nearby caravan parks. The walk probably takes forty minutes to an hour depending on how many times you stop to stare at birds or muddy water. Families with younger kids might find it a bit quiet - there's not much to do except observe - but anyone who enjoys spotting wildlife or just wants a break from the holiday park routine will find it worth the trip.

Check locally in Retford before you go about access and whether there are any seasonal closures. Free admission as far as these reserves tend to go.
