"Ings" is an old Norse or Viking word meaning marshes or water meadows. Clifton, Rawcliffe & Poppleton Ings form a major part of the flood defences, both for the City of York and further downstream. When full, the Ings can hold 2.3 million cubic metres of water. The water level is controlled by sluices at the north and south ends.

There's plenty of parking in the park & ride, and a short walk through the Country Park. Look out for bikes, joggers, dog walkers... If you're on the cycle path at GZ, any cows should be the other side of the fence.
YOU DO NOT HAVE TO MOVE ANY ROCKS!
