Jet Skiing in New Jersey’s Largest Jet Ski Rental Zone is a great way to let loose and enjoy the beautiful Raritan Bay and Keyport NJ waterfront. Especially great for beginners, this huge supervised rental area is the next best thing to owning a jet ski (well, maybe better since there aren’t ownership headaches!). This 60 minute jet ski session is a picturesque experience that’ll have you coming back for more!
