When planning your visit, plan to attend a ranger-led program. While cave tours are offered all year long, during the summer many other interesting programs are offered. These programs include 5 different cave tours, a ranger-led prairie hike, discovery programs, and evening campfire programs. Topics might include cave history, geology, the relationships of the plants and animals, the importance of fire to the park's ecosystems, or other natural or cultural history topics.
All cave tours are ranger-guided and leave from the visitor center. Tickets are sold on a first-come, first-served basis. During the summer months long waits may be encountered. To avoid waits, the best time to visit the cave is during the early hours of the day. During the summer weekends are good times to visit; Tuesdays and Wednesdays are the busiest days.
