The region has a wealth of great attractions, many of them run by volunteers and enthusiasts, which have a niche following, but are hidden away.
Some of them only open occasionally, or just a few days a week - but these 13 museums shown in the gallery below provide great trips out if you can catch them at the right time.
You will find them in South Yorkshire and North Derbyshire.
