.5 Miles Difficulty III: The park’s most impressive geologic features are revealed on this short walk that begins from the Devil’s Icebox parking lot. A boardwalk trail makes it easier to climb the 63-foot-tall Rock Bridge and eventually loops around to bring you back through the natural tunnel. To protect the resource, please stay on the trail. Features visible along the way include the valley that formed when the cave roof collapsed to form the Rock Bridge, a glade in the process of being restored, and the double sinkhole entrance to Devil’s Icebox Cave and Connor Spring. The walk down the stairs to the cave entrance is refreshingly cool in summer months. Enough light enters the karst window to allow a short wade in the underground stream. Flashlights, helmets and good shoes are recommended for those brave enough to enter the darkness of Connor’s Cave, which lies downstream or to the left of the entrance to Devil's Icebox Cave. Devil’s Icebox Cave begins to the right or upstream from the cave entrance. Only those on park-led wild cave tours are permitted to enter Devil’s Icebox Cave. From the caves, the boardwalk meanders through the woods and keeps visitors’ feet dry inches above the stream that flows through the Rock Bridge. Displays tell visitors more about the cave system and the area’s history. Additional information can be gained from using the Devil’s Icebox Self-Guiding Trail booklet, which is available for a small fee at the park office.
