Overview
A brief introduction to Spring Mill State Park
Spring Mill State Park is a 1,358-acre (5 km2) state park in the state of Indiana. The park is located to the south of Bloomington, about 3 miles (5 km) east of the city of Mitchell on Indiana Highway 60. It contains a settler's village, the Gus Grissom Memorial (with the accompanying Gemini 3 space capsule), a nature center, and campgrounds.
The park is located on the Mitchell Karst Plain, which allowed the park's caves and sinkholes to form in the limestone. The caves include Bronson Cave, Twin Caves, Shawnee Cave (Donaldson Cave), Hamer Cave, and others. A boat tour of Twin Caves is run by the Indiana Department of Natural Resources, which travels about 500 feet (150 m) into the cave.
A portion of the park is virgin timber, protected in the Donaldson Woods Nature Preserve. The Mitchell Karst Plain Nature Preserve is notable for its large number of sinkholes, more than 1000 per square mile. Many of the park's features were constructed by the Civilian Conservation Corps in the 1930s, including the Spring Mill Inn, Spring Mill Lake, and most of the trails. The park attracts about 675,000 visitors annually.
The park is 1 of 14 Indiana State Parks that are in the path of totality for the 2024 solar eclipse, with the park experiencing 3 minutes and 21 seconds of totality.
