Crystal Ball Cave, located in western Millard County, is a geologic marvel. Tours are offered by the Bates Family at the Bates Family Ranch. Inside this natural limestone cave, you’ll find bizarre formations like stalactites, and stalagmites, cave coral, and walls of crystal. It’s like walking inside a giant geode. Exploring the rooms and tunnels with Kiersten, the tour guide, is a very cool activity for the whole family. Kids especially love crawling around it.
