One of the Midwest’s biggest theme and amusement parks, Six Flags is midway between Chicago and Milwaukee on I-94 in Gurnee, Illinois. The park has more than 100 rides and attractions and is a favorite of roller coaster devotees. The wooden daredevil coaster, Goliath, is a major attraction (think mind-blowing, record-breaking heights, speeds, and inversions). That’s in addition to Superman, where you speed along hanging headfirst (with your legs dangling). Other don’t-miss rides for the strong of stomach include Raging Bull, the "world’s first hyper-twister roller coaster," and American Eagle, a classic wooden coaster. Because this place caters to families, you’ll also find plenty to appeal to smaller visitors, with three distinct kids' areas. Hurricane Harbor, a massive water park with a giant wave pool, is fun on a hot day, but you risk heatstroke waiting in the long lines. Six Flags also has live shows, IMAX movies, and restaurants. If you take the trouble to get out here, allow a full day.
