Think, Go Ape but indoors, now think Go Ape but indoors and miles cheaper ! BOOM you have Sky High ! Not as big as Go Ape but i think you wallet or purse is better off. Loads of different climbing walls with levels of ease and variety of climbing. Then there is indoor cave exploring and high rise walks. Café was a bit poor on my visit. Hot drinks a little expensive(over £2) and there was two selections for food for kids and adults. Apart from that my 5 year old daughter had loads of fun. Would recommend
