When you visit Spring Mill State Park in your RV, your eyes will be opened to the ways that nature and culture come together to form something absolutely amazing. In the 1800’s, pioneers founded an industrial village here after discovering the water that flows through the cave springs. They used the power of the flowing water to create grist mills, a saw mill, a wool mill, and even a distillery.

Now, you can experience all of this great history for yourself by visiting the Pioneer Village, the Nature Center, and Grissom Memorial. You can also discover the caves with the Twin Caves Boat Tour. There is so much to see and do at Spring Mill State Park, it’ll take a few days to see it all. Bring your RV for a camping trip so you can fit it all in.

Special events and programs take place all year long, so any time is a great time to visit. In the summertime, you can expect warm weather up into the 80’s, but during the winter temperatures drop to the 20’s. Either way, there is always something to get into when you bring your RV and camp at Spring Mill State Park.
