MonstroCity In St. Louis
Another amazing playground that also is made from recycled items is MonstroCity in St. Louis, Missouri. There is even a four-story interactive sculpture that is intended for both children and adults. Some of the other features include tunnels that make it feel as though you are crawling through the sky, huge ball pits, and massive slides. This amazing playground is connected to the City Museum which has other fantastic play features including a human-sized hamster wheel and caves to explore. There's something for kids and adults of all ages here!
