Spring Mill State Park, located just east of Mitchell (Indiana) is a very unique park indeed. Centered around an 1800’s community and its gristmill, visitors of all ages will be delighted by well-preserved homes and businesses as they get a glimpse into life in southern Indiana in the early nineteenth century.
Pioneer entrepreneurs took advantage of a water source that would never freeze, using it to power gristmills, a saw mill, a wool mill, and distillery. In turn, pioneer settlers worked hard to shap the landscape around the village, clearing land for agriculture and timber. Their water source that never froze? A cave in the side of a hill located just a hundred yards upstream that you can easily get to.
Speaking of caves, Spring Mill has several of them. The most interesting caves are the Twin Caves. A stream rushes out of one and travels into the other a short distance down stream. Boat tours are offered into Twin Caves and it is a unique trip worth taking for the family. Other caves dot the park, but several have been closed to help protect the Indiana Brown Bat and other species.
Spring Mill is also a celebration of one of America’s most famous astronauts. Virgil “Gus” Grissom was a native of the area and flew in several NASA space flights. He was the first to fly in the Gemini Project and was scheduled to be the first in the Apollo Missions as well. A fire on the launchpad, however, cut this native son’s life short. This national tragedy helped to bring new safety measures to our space program.
Spring Mill has many things to offer visitors. From caves to historical settings to hiking to a memorial for a fallen hero, this state park has much to offer families with all ages of children. Below you will find information as provided by the Indiana Dept. or Natural Resources.
