Wonder World Park is a unique theme park that holds the honor of being home to the only accessible earthquake cave in the United States. Guided tours first bring visitors underground, where trained guides provide information about the area's geological history and walk them past the cave's many unique formations. After spending some time underneath the Earth, visitors can shoot up to the park's observation tower on an exhilarating elevator. The park offers several other attractions as well, including a petting zoo, an anti-gravity house, and a trackless train that brings visitors underneath a waterfall.
