Arrrrrr, matey. We landlubbers may be hundreds of miles from the sea, but that doesn't mean we can't sail (or drive) away to our very own isle. Plopped between the Mississippi River and the Chain of Rocks Canal, Chouteau Island is accessible via a narrow two-lane bridge from Madison County, Illinois. In recent years the Illinois Department of Natural Resources has acquired nearly half the land on the 3,200-acre island and plans to build biking and hiking trails connecting the Confluence Bikeway and the Riverfront Trail in Missouri. For now it remains mostly farmland and forests, lending it the same bucolic landscape that Lewis and Clark must have enjoyed when they camped there before embarking on their 1804 expedition.
