There is a lot to do at Snibston: it is a science park built on on a disused cola mine, and can be as educational, or not, as you wish. We have had season tickets for years (a family ticket is relatively cheap) and my children have yet to get bored of the place. At various times there are train rides, activities such as crafts, and coal tours, check before you go. Even without them, there is stacks to do. In the summer, the Wild water exhibit is open, which is basically a model of a canal system: be warned, children are likely to get soaked. Mine would go to Snibston just for this. There is an outdoor play area, an indoor under-5s area (excellent facilities), a fashion and textiles exhibition, full size steam trains, planes and buses. You can dress up as a miner and play in a 'coal mine tunnel'. We have been on a 'bat walk' and been pond dipping in the beautiful nature reserve. But the most favourite thing: my children love having their picnic lunch inside an old railway carriage. I would say the museum is well worth the entrance fee, but bring your own food (lots picnic tables, both indoors and out) as the food on offer is pretty poor.
