Memorial Day is the unofficial start to summer, and nothing says summer more than fun on the water. Water World, listed as one of the coolest water parks in America, opens today for the summer season. Water World offers rides that range from steep slippery slides to raft rides down the "Lazy River." The wave pool is ideal for wading, and Wally World, with geysers and shallow water slides, is perfect for the little ones.

America's largest family water park features over 40 aquatic attractions on 67 beautifully landscaped acres including the Rockies first water coaster, giant wave pools, white-water rapids, speed slides, Voyage to the Center of the Earth, Big Top Family Fun Zone, Wally World for tots and more. Free parking, picnics welcome.
