Box Rock Circus

You'll find a converted quarry near Bradford-on-Avon that's been turned into something genuinely odd - a circus museum carved into the rock itself. Box Rock Circus is free to visit and accessible round the clock, which means you can roll up whenever suits your campsite schedule without worrying about opening times.

The appeal here is fairly niche. If your family includes circus enthusiasts or anyone fascinated by the history of performance and showmanship, it's worth a detour. The setting itself - literally inside a working quarry - has more character than your standard museum housed in a converted barn. You're walking through actual stone galleries with circus memorabilia, vintage posters, and equipment from travelling shows. Kids under eight might lose interest after thirty minutes, but teenagers into odd history or unusual venues tend to stick around longer.

Allow a couple of hours maximum, especially if you're combining it with other attractions in the area. The 24/7 access is genuinely useful if you're based at one of the nearby parks - Campwell Farm, Piccadilly Caravan Park, or Marsh Farm - and fancy a quiet evening walk without daylight constraints.

Bradford-on-Avon itself is the real draw if you're staying locally: a proper Georgian town with decent walking trails along the Kennet and Avon Canal. Box Rock Circus works as an unusual add-on rather than a full day's entertainment, but if you're already in the area, the free entry and accessible location make it easy to tick off.
