Royston Splash Park

Water and wildlife collide at Royston Splash Park, a nature reserve that does exactly what it says on the tin. You get shallow pools, marshy bits, and proper open space where kids can actually run about without worrying about getting soaked - though they probably will anyway. The reserve is dead useful if you're camping nearby, particularly with families who need to burn off energy between trips to Guilden Gate Glamping or Shepreth Mill just down the road.

It's the kind of place that rewards a proper wander rather than a quick tick-box visit. Bring binoculars if you're into birds - herons and dragonflies are regular sights depending on the season. The walking is gentle, nothing strenuous, which means grandparents and toddlers can manage it together without complaint. Allow a good hour minimum if you're not just doing the perimeter loop.

The real magic happens in summer when the water levels are up and the whole place feels alive. Winter's wetter and muddier, which younger kids find brilliant but means proper wellies are non-negotiable. There's no cafes or facilities that I'm aware of, so bring what you need.

If you're based at one of the caravan parks nearby - Ashridge Farm and Pightle Farm are both within easy driving distance - this makes a cracking free addition to your holiday itinerary. It's not a full day's entertainment on its own, but paired with a walk into Royston town itself, you've got a solid morning sorted.
