Did you know that Kaskaskia Island is the only piece of Illinois land west of the Mississippi River? Once the first capital of Illinois and home to over 7,000 residents, this historic island was dramatically transformed in 1881 when the Mississippi River changed course during a devastating flood, cutting it off from the mainland. Today, this geographical oddity is accessible only by road from Missouri, despite remaining part of Illinois—a fascinating quirk that makes visiting this hidden gem a truly unique experience.
