Saltersford Locks

Four working locks on the River Weaver make for a surprisingly engaging spot to spread your rug and watch narrowboats navigate the water steps. The locks themselves date back centuries, part of the network that once carried salt from Northwich to markets across England. Today they're still in use, so you'll likely catch a boat or two working through while you eat your sandwiches.

Families get the best deal here. Kids love watching the lock gates open and close, the water rushing in and out as boats rise or fall. There's decent grass space for running about between boat movements, and the towpath makes for an easy walk in either direction if little legs need stretching.

Don't expect facilities - this is raw countryside, so bring everything you need including water and pack out your rubbish. The appeal lies in its working nature rather than manicured amenities. Spring through early autumn works best when the locks see regular traffic and weather allows comfortable outdoor eating.

Worth combining with a stay at one of the nearby parks around Northwich. Delamere Lake Sailing & Holiday Park sits less than five miles away, while several others like Blakemere Holiday Park offer easy access to this slice of Cheshire's industrial waterway heritage. Allow an hour or two depending on boat activity and how long the children remain fascinated by hydraulic engineering in action.
