Illinois's Great River Road follows the Mississippi River through the heart of the nation, offering history, thriving river cultures, beautiful natural areas, abundant wildlife, and bountiful agriculture. Along the route, the history and heritage of the Mississippi River and Middle America come to life through prehistoric Native American cities, forts that guarded the river during three wars, several National Historic Districts, and other treasures of the nation's history. The beauty and panorama of the Mississippi River and the nation's heartland are visible in every season along the 550-mile road, with ever-changing vistas and sights. The nation's largest river also provides countless opportunities for wildlife watching, nature study, and outdoor recreation, from watching eagles to fishing in secluded backwaters. Farming and agriculture along the Mississippi River have helped feed the nation and much of the world, and the route offers views of fertile crop fields, big farming equipment, and modern wineries that reflect rural America.
