About Indiana Caverns

Our Story, Unique Discoveries, and More

Indiana Caverns opened its doors to the public on June 15, 2013, after an immense cache of significant prehistoric remains were discovered. Just months after its opening, a four-person speleological survey team added 1,763 feet of a recently discovered section of the Binkley Cave system known as the Wild Wild West, putting Indiana Caverns in the top 7 of the longest caves in the United States, with much more to be mapped.

Today, Indiana Caverns is the longest cave in Indiana.  We offer a full range of activities on our property including walking cave tours,  cave exploring, Bat Chaser zip coaster, the Plunge, Escape Rooms, Gemstone Mining, and more.


Gary Roberson, Developer of Indiana Caverns, Crawls into His First Cave

Gary Roberson crawled into his first cave on his first Boy Scout camping trip as a Tenderfoot scout in 1958. He became an active caver the day he received his driver’s license and began mapping in the Binkley cave system in 1967 while attending Vanderbilt University, where he graduated with a business major.


Surveying of Binkley Cave System Begins

Surveying of the Binkley Cave System, which is a part of the Indiana Caverns show cave, began in 1957, over 60 years ago! Surveying continues of the Binkley Cave System as it’s believed there are over 100 miles to be mapped.


Massive amounts of Ice Age bones found.

When the Indiana Cavern’s portion of Binkley Cave system was discovered in 2010, massive amounts of bones were seen: birds, snake, microfauna, and larger species. The name “Big Bone Mountain” was coined immediately. The five hour crawl through water to glimpse the bones kept them in mystery for almost two years.


The Binkley Connection

On Saturday, February 11th, 2012, a connection between Blowing Hole and Binkley Caves were discovered. The Binkley Cave System became the 11th longest in the nation and the longest in Indiana. Their combined length totaled 35.89 miles with more passageways awaiting discovery. The impact of this discovery was huge. A public entrance to Binkley Cave could now be created to allow visitors into the cave system. Previously all entrances were located on private property with restricted access. As of October 2016, the cave is over 43.9 miles long.


Paleontologist Visit

With the creation of a new entrance in 2012, the first paleontologist visited. During his initial 6-hour visit, the state paleontologist saw 11 peccary skulls, a black bear skull, a juvenile bison, a fisher skeleton, bird bones, a snake, bear wallows, and claw marks. He immediately realized our bones were extraordinary and of significant importance.


Show Cave Officially Open for Public Tours

After an immense cache of significant prehistoric remains was discovered and preserved, Indiana Caverns officially opens for public tours in June of 2013. The development phase to get it ready for the public took 380 days to prepare.


Indiana Cave System Now in Top Tier of American Caves

A four-person speleological survey team added 1,763 feet of a recently discovered section of the Binkley Cave system known as The Wild Wild West. The new, established survey length of 38.452 miles means this cave is now the ninth longest in the country. The team explored at least another 1,000 feet of walking virgin cave beyond the official survey, demonstrating that there is much more cave to be mapped.


An excavation, led by the Indiana State Museum, to identify and classify Ice Age Bones found at Indiana Caverns. Indiana State Museum staff have been conducting excavations in other caves for over 30 years and found just one complete Peccary skull prior to discoveries at Indiana Caverns. 


In 2019, Indiana Caverns expanded to Indiana Caverns Family Adventure Park adding an outdoor attraction, the Bat Chaser, a single rail zip coaster.
