||During "Weekends on the Boardwalk", you can enjoy a free guided tour of Connor's Cave using park lights and helmets. Walk the Devil’s Icebox Trail on your own until you reach Devil’s Icebox where park volunteers will assist you. Learn about caves and bats. Tours last about 15 minutes. Expect to get your feet wet. Tours will be offered on most Saturday and Sunday afternoons June 14 through August 31. Because cave tours will not be offered when we lack naturalists or the weather is inclement, please call 573-449-7400 to learn about specific dates. Reservations are not required. You may arrive anytime between 1 and 4 PM. Recommended for ages 5 and up.
