Overview of the 6 Largest Indoor Water Parks in the U.S.

While swimming outside can be a blast during the summer, you’re at the mercy of factors like weather and rip currents. Indoor water parks allow you and your family to enjoy warm, sunny, and safe conditions year-round. You don’t have to worry about getting sunburned or avoiding jellyfish stings. And if you live in an area that stays relatively cool throughout the year, you can enjoy splashing and swimming whenever the mood strikes. Check out the six largest indoor water parks in the U.S., including where they’re located, how big they are, and what they offer.
