Grimsby Leisure Centre

The leisure centre sits right in Grimsby itself, about five miles inland from Cleethorpes, and it's the sort of place that works best if you're already staying in the area with kids who need burning off some energy. Swimming pools, gym facilities, sports halls - the standard local authority setup. Nothing flashy, but it does what it says on the tin.

You'll want to bring the family here on a rainy afternoon or when the beach gets too crowded. The pools are decent enough for a couple of hours, and older kids might fancy the sports facilities if they're into badminton or squash. It's not going to blow your mind, but it's exactly what you need when you're based at somewhere like Haven Cleethorpes Beach Holiday Park and the weather turns.

Best to ring ahead or check their website before you head over - opening hours can be unpredictable at council-run centres, and pricing varies depending on what you're using. An hour or two is about right before everyone gets bored. The location near Grimsby town centre means you could tie it in with a proper lunch somewhere, though honestly you're better off heading to Cleethorpes itself if you want proper attractions and fish and chips. This is functional, not destination stuff.
