Mississippi Palisades State Park near Savanna is a dramatic stretch of limestone bluffs, caves and sinkholes above the Mississippi River in northwest Illinois. Tall cliffs and sweeping river views make it one of the most beautiful parks in the state. About 15 miles of trails wind through forest and along the bluff tops, leading to overlooks and interesting rock formations. Camping is available for those who want to stay longer, and bald eagles and other wildlife are commonly seen along the river, especially in winter. There is no vehicle entry fee, and camping fees vary by site, from $8 to $45 per night. Fall color is spectacular from the bluffs.
