The Kentucky Karst Conservancy promotes cave access, cave education, conservation projects, cleanup projects, and many other activities. Additionally, we own an entrance to Big Bat Cave in Hardin County. All these activities are volunteer run, but take money to pay for materials and our mortgage. Your donations will help us to continue pursuing preservation and cave access throughout Kentucky.
