Illinois Beach State Park
🌿 Trusted Guide to Illinois’ Last Natural Shoreline – Updated 2025
6.5 Miles of Lake Michigan’s Only Natural Shore in Illinois
In the city of Zion in Lake County, Illinois Beach State Park (officially Adeline Jay Geo-Karis Illinois Beach State Park) protects 4,160 acres along 6.5 miles of Lake Michigan’s only remaining natural beach ridge shoreline in Illinois. Split into North and South units, the park harbors sand dunes, wetlands, black oak savannas, and over 650 recorded plant species — including prickly pear cactus, an unexpected find this far north. The South Unit’s nature preserve is a National Natural Landmark (1980), protecting rare dune-and-swale habitats found nowhere else in the state.
