About Spring Mill State Park

As featured in Midwest Magazine, beautiful Spring Mill State Park in southern Indiana abounds in endless opportunities for recreation.  Cave tours, boating, hiking, mountain biking, nature activities, swimming and much more await you.  You can also visit a restored Pioneer Village that dates back to the early 1800s, as well as the Gus Grissom Memorial Museum honoring this famous Hoosier and local NASA astronaut.

There is so much to see and do at Spring Mill State Park – you owe it to yourself to stay a night or two and take your time exploring it all.  You can relax at the Spring Mill Inn, camp in a tent or RV in the campground, or utilize other nearby lodging options.

Spring Mill State Park offers a powerful illustration of the link between the natural and cultural worlds.  The water flowing from several cave springs led to the founding of an industrial village in the early 1800s.  

Pioneer entrepreneurs took advantage of a constant water source that never froze, using it to power several gristmills, a wool mill, a saw mill, and a distillery.  In turn, pioneer settlers shaped the landscape around the village, clearing land for agriculture and timber.

The park today continues to illustrate how nature shapes us and how we shape our environment.  A parcel of virgin timber in Donaldson Woods sits in contrast to regenerated forest. 

 The man-made Spring Mill Lake struggles to survive against the in-flow of silt from cave-fed systems.  The native flora and fauna face challenges from man’s introduction of new species.

Visitors can explore this story in the park’s four interpretive facilities—the Pioneer Village, Nature Center, Grissom Memorial, and Twin Caves Boat Tour — and see it reflected on the landscape as they hike the trails.  The interpretive staff also offers a wide variety of public programs, including an extensive special events schedule.  Public programs are offered year-round.
