Market Harborough Library (with Family Hub support)

Market Harborough's library sits right in the town centre, and it's the sort of place that sneaks up on you. Not flashy, but genuinely useful - especially if you're camping at one of the nearby sites like Get Lost In Nature or Buttercup Meadow and need to escape a rainy afternoon. The Family Hub element means there's proper support for parents with young kids: activities, advice sessions, sometimes craft bits on. It's free to browse, obviously, and the staff know what they're doing.

The town itself is charming enough without being saccharine about it - proper market town with actual independent shops rather than chains. The library slots in nicely as a rainy-day refuge or a spot to charge devices and grab some peace. If you're staying at one of the caravan or glamping sites within five miles, it's worth knowing about for when the weather turns.

Really, you'd spend thirty minutes to an hour here, maybe longer if you're a book person or need to use the computers. Kids get bored if there's nothing on, so check what's running when you visit. Not a headline attraction, but the sort of thing that makes a park holiday feel less isolated - you can pop into town, sort yourself out, and head back to the countryside. The Family Hub side means parents won't feel awkward bringing young ones in.
