Spring Mill State Park offers a rare journey through time—and space. At its heart lies a meticulously restored 1814 pioneer village with a working 1817 grist mill still grinding cornmeal today. Below ground, you can explore limestone caves by boat. And honoring Indiana’s most famous son, the park houses the Virgil “Gus” Grissom Memorial—celebrating the Mitchell native who became the second American in space. From 200-year-old history to Space Age heroism, Spring Mill delivers an unforgettable experience.
