America's Coolest Indoor Water Parks

Endless summer -- that's the promise of indoor water parks. And with it come surfing contests hundreds of miles from an ocean, waves lapping at pools the size of small lakes, and bright beach towels spread over lounge chairs as snow falls outside the windows.

The coolest indoor water parks keep kids of all ages entertained, from Idaho to Texas to New Hampshire. While some also have outdoor rides that close at summer's end, nothing can slow down the splashing excitement inside, where air temperatures remain between the high 70s and high 80s year round.

Minnesota's Water Park of America's 90-foot-tall Eagle's Nest Tower anchors four wild slides -- one stretching more than a mile -- while in Wisconsin, the Klondike Kavern's Hurricane shoots riders up for a moment of weightlessness.
