Mountain Creek Water Park is a water park in Vernon Township, USA. The park opened on 1998, is located on the original site of Action Park, one of the first modern American water parks, which was open from 1978 until 1996. The park consists primarily of water-based attractions. The best rides here are H2-Oh-No! and Zero-G. Other rides which I recommend you try are Colorado River, Bombs Away, Alpine Rush and Thunder Run.
