7. Runaway Rapids Waterpark
Address: 275 Beachway Ave, Keansburg, NJ 07734
Halfway through our list of the best indoor and outdoor water parks in and around New York City is the Runaway Rapids Waterpark. This facility is owned and operated by the same folk who run the adjacent Keansburg Amusement Park. The water park has over 18 fun rides complete with a separate play area for kiddies. The awesome thing is, you can buy a combo ticket and enjoy both parks at a much cheaper price.
