Beyond Chicago’s skyline lies a surprisingly wild Illinois. Wander sandstone canyons and waterfalls in Starved Rock, paddle the Mississippi backwaters, or explore the hardwood hills of Shawnee National Forest. Route 66 nostalgia, river towns brimming with blues, and autumn foliage drives mean plenty of culture between hikes. Park the rig, grill up a deep-dish-inspired camp pizza, and let the Prairie State show its natural side.
