Spring Mill State Park Caves

3333 State Road 60 E., Mitchell; on.in.gov/springmill

This state park in Mitchell has a host of caves to explore. From the Donaldson Cave to the Bronson Cave to the matching Twin Caves, navigate all Spring Mill State Park as to offer by boat or on foot. You might spot a blind Hoosier cavefish or other aquatic life swimming in the streams, which stay 54 degrees year-round. Visitors must register in advance and can tour in groups or go solo. Other attractions at the state park include hiking trails, a pioneer village with restored historic buildings and a memorial and museum honoring Mitchell native Gus Grissom, the second American in space and one of three astronauts who died during Apollo I testing.

Wyandotte Caves

7315 S. Wyandotte Cave Road, Leavenworth; https://bit.ly/3DnxMZe

Big, Little or both – take everything in at the Wyandotte Caves State Recreation Area, which recently reopened for tours. Catch rare rock formations and the underground "Monument Mountain" in the mile-and-a-half trip down Big Wyandotte, or keep it smaller on the half-hour tour of Little Wyandotte. Campsites at the nearby O'Bannon Woods State Park are available for an overnight stay, and tours are open every day of the week. Better book fast, though: Big Wyandotte will close for tours after Labor Day Weekend, and Little Wyandotte is only open through October.
