Winter certainly has its charms: building snowmen, sledding, skating, and hot cocoa are wonderful, but by mid-January you and your family might be looking to warm up in a more tropical environment. While it might be nice to board a plane to a sunny island destination, it’s not always possible or cost-effective. Luckily, you can enjoy some summertime fun even in the coldest months at a multitude of indoor water parks and pools in and around New Jersey. All of these destinations can be reached in about three hours or less by car, give or take your starting address and traffic, of course. Go dig out your bathing suit from behind your coats and mittens, and get ready to take the plunge at one of these exciting parks!
