Horley Leisure Centre

Horley Leisure Centre sits just outside Crawley and serves as a proper community hub rather than a destination attraction. You'll find a swimming pool, gym facilities, and sports halls - the kind of place locals pop into on a rainy Tuesday afternoon. If you're camped nearby at Gatwick Caravan and Motorhome Club or Henfold Lakes, it's worth knowing about for a wet day or if your kids need burning off.

The pool is the main draw for families. It's indoor, which matters when you're staying in a caravan and the weather turns grey, and there's usually a shallow end for younger swimmers. The gym and sports facilities won't excite anyone on holiday - you're not here for that. What you will find is a functioning, well-maintained leisure facility that takes the pressure off when you're stuck indoors.

Access and costs run through Better, the leisure management charity, so you'll need to check their website for current prices and session times. It's not free, but it won't break the bank. Allow an hour for a swim, maybe two if you're taking it slowly with small children.

Honestly? It's a backup plan rather than a reason to choose a park nearby. But if you're camping within a few miles - which several parks are - and the forecast looks miserable, knowing it's there takes the edge off. Not everyone will need it, but when you do, you'll be glad of it.
