There is so much to “see and do” at Spring Mill State Park

Pioneer Village

Pioneer Village

Immerse yourself in history by taking a step back in time to the early 1860’s.

The showcase of the Pioneer Village is the Grist Mill. This limestone mill is an original structure that was built in 1817 and still grinds corn to this day. Water flowing out of Hamer Cave pours over the enormous water wheel and drives the gears that spin the grindstones.

Visit over 20 historic structures, and learn their stories.
