Sullivan Cave

Sullivan Cave is owned by Indiana Karst Conservancy (IKC). They aim to protect the Karst landscape of Indiana. The pathways are not illuminated, making it unsafe for one to walk through. The IKC states that the cafe has been classified as a natural and wild cave, meaning no improvements will be entertained. It’s important to note that you can only explore Sullivan with the help of an experienced caver, not unless you are an advanced caver.

Some of the notable features in Sullivan Cave include The Colossus and Mountain Room, which boasts large stalagmite and several other formations hanging from the ceilings and sides of the rooms. The Sullivan Cave is home to a wide array of biological life, including amphipods, beetles, salamanders, isopods, cave crayfish, and a small bat population of Pipistrelles.

Buckner Cave

Buckner Cave is a typical example of a Karst Cave located in Monroe County, Indiana. There is a serious ongoing effort to restore the cave to its original condition after being vandalized for many years. Garbage-like food wrappers and broken bottles were common all over the Buckner Cave. The Richard Blenz Nature Conservancy has been managing the cave since 2005 though he recently donated it to the National Speleological Society.

Visitors don’t require any special equipment or ropes to traverse the cave. However, many areas have low ceilings, so one will be required to crawl on hand and belly. While exploring the cave, you may encounter several bat species, like the Pipistrelle, the Indiana Bat, and the Big Brown.

  • Entrance fee for both caverns: : Free, but one needs to take a permit one week in advance from the Richard Blenz Nature Conservancy since the cave is privately owned.

Wolf Cave Nature Preserve

Wolf Cave is the top draw at the McCormick Creek State Park in Spencer, Indiana. It’s one of the perfect places to visit, especially if you want to avoid crowds. The cave was formed by underground water movement that dissolved the limestone bedrock and carved out a beautiful network of passageways. Over time, erosion exposed the cave, and now it’s completely dry.

Wolf Cave is home to numerous birds, including thrushes, wood warblers, tanagers, and cerulean warblers. There are not many geological formations to see, but you will still love the experience of exploring the cave, while spotting hints of the underground streams that formed the passageways.
