This place is wonderful. Plenty of space for kids (and adults) to run and walk. There are some small adventure play/obstacle course type areas for older kids, a small play area for younger kids and a large play park for all ages. There is also the science bit inside where there are interactive exhibits.
Most of the place is outdoors so it's best on a nice day but still great any time of year. There are regular falconry displays which my family absolutely love. There are also different educational shows at the amphitheatre unfortunately, I seem to miss all of them! There is a train which takes you from one side of the park to the other.
My favourite bit is the Barefoot Walk. Take your shoes off and feel the clay, the cold water, the shale, the coal It's so refreshing. It has been extended but I still think it should be longer! I would pay the entry price just for that.
There are a couple of places to eat and drink although I would recommend taking a picnic because those places are a little expensive.
The only things I think could be improved are: there are very few toilets. They could do with putting one or two in the places which are further from the entrance! Also, the parks/play areas/obstacle things are quite spread out so if you have children of very different ages, that can be awkward.
Otherwise, it is a great day out. I think it costs around £30 for a family which includes all of the attractions (apart from one or two fairground type rides which are £1 or £2 and can easily be avoided!) read more
