Squire Boone Caverns is a limestone cave system discovered in 1790 by Squire Boone, the younger brother of frontiersman Daniel Boone. The site features an active underground river and several large waterfalls, including the tallest in any cave in Indiana. Above ground, the property functions as a pioneer village offering historical demonstrations like grist milling and candlemaking. The cavern temperature remains a constant 54 degrees Fahrenheit year-round due to its subterranean environment. The attraction is located in Harrison County, Indiana, near the Ohio River. Visitors navigate the cavern via guided tours that highlight unique geological formations and rock bridges. The village area preserves structures and crafts reminiscent of early 19th-century frontier life. The site is a registered Indiana historic landmark.
The large waterfall inside the cavern provides the most iconic visual backdrop.
Bring a light jacket or sweatshirt, as the underground temperature is cool regardless of surface weather.
Wear shoes with good traction, as the cave paths can be slippery and wet.
Allow extra time to browse the pioneer village shops and watch the craft demonstrations after your cave tour.
Do not attempt to explore the cave system without a guide, as the terrain is protected and hazardous.
The attraction occasionally limits cave tours or closes certain village activities during extreme winter weather or flooding; verify site-wide availability if visiting in late winter.
Touching formations is strictly prohibited to prevent oil damage from human skin; sturdy, closed-toe walking shoes are required.
