The story

Wonder World Cave was discovered in 1893 by Mark A. Bevers, a former cowboy and freight hauler, while he was drilling for water in what is now the park's parking lot. In 1903, W.S. Davis took over Bevers' Cave and began operating it as a tourist attraction. The cave later became the property of Judge Will G. Barber, who sold it to Arthur B. Rodgers in 1916 for $50, a gray horse, and a saddle. Rodgers installed electric lighting, gravel paths, handrails, and ladders, and renamed the cave Wonder Cave. The park has been family-owned and -operated, and in 2017 Kristin Mostyn Williams, the third generation of her family to run it, took over.
