Camp Snoopy was cute and all, what with its Peanuts characters and fairly large variety of rides. And its successor, Nickelodeon Universe, will certainly be fun for the little ones, but adults probably aren't going to be thrilled by Sponge Bob Square Pants and Dora the Explorer. Thankfully, Valleyfair offers attractions for both the kiddies and adults (think water rides and shriek-inducing roller coasters). Opened in 1976, Valleyfair melds classic amusement park rides and coasters, including the wooden High Roller, with the latest generation of terrifying steel rides, including Steel Venom, which plunges its passengers 175 feet at 68 mph. Children can keep busy with mild thrills in the aptly named KidWorks section of the park. And for cool fun in the thick of summer, Valleyfair's Whitewater Country water park has five waterslides and raft attractions. Plus there's Valleyfair's Challenge Park, which features several low altitude activities, including go-carts and miniature golf.
