This National Natural Landmark is one of the largest prairie remnants in the state, though the area immediately south and west of the parking area is reconstructed. Late summer is best, but every season offers something. Despite its size, Hoosier Prairie is not large enough to offer a complete escape from civilization. Noise from nearby highway and rail traffic is virtually continuous and usually loud, while large petroleum tanks loom to the south.
A graveled path extends south from the parking area, intersecting the first of two joined loops that extend east into virgin prairie. The plant mix varies with elevation. Low areas are wet and host cattail, sensitive fern, iris, and amphibians. Plants typical of tallgrass prairie populate higher ground; look for coneflower, rattlesnake master, blazing star, vervain, and the like. The eastern-most loop occupies yet higher ground, dominated by oak savanna, with bracken filling much of the understory.
Directions: Lake County. From US 41/Indianapolis Blvd at the border of Highland and Schererville, go east 0.75 miles on Main Street to the parking area on the right.
