Squire Boone Caverns, Show cave in Harrison County, Indiana, United States
Squire Boone Caverns is a show cave featuring underground streams that flow through passages carved in limestone, with waterfalls and mineral formations visible along the pathways. The cave system extends roughly one-third mile beneath the surface and maintains steady natural water flow year-round.
Squire Boone and his brother Daniel discovered these caverns in 1790, and their exploration led to a settlement and grist mill being built in the area. The cave system became important to the early community that relied on its water for daily operations.
The old grist mill on the grounds still uses water from the cave to grind grain using traditional methods that have been passed down for generations. You can watch this working craft and see how the flowing water shaped the way people lived and worked in this area.
The cave maintains a constant temperature around 54 degrees Fahrenheit (12 degrees Celsius), so bring a light jacket to stay comfortable while exploring. The underground pathways are manageable for most visitors, though sturdy shoes are helpful for maintaining good footing on the damp surfaces.
Squire Boone was buried in a chamber within the caverns according to his final wishes, resting in the place he discovered and loved. This burial makes the cave a living memorial to one of the pioneers who shaped the region.
