Expedition groups explore approximately 80% of the cavern system from the east entrance to the western most exit of California Cavern. The circuit is about a mile long, so stamina is required! The first hour of the trip consists of walking, crawling and squeezing through the historic “Mammoth Cave” area.
Then groups pass through the “Middle Earth” area which was discovered in 1980. Here there is mostly walking through nearly knee deep, sticky cave clay (high top shoes are a must) and the scenery is incredibly beautiful.
The remainder of the trip consists of exploring the horizontal fissures in the “Cave of the Quills” area and a quick, 70-foot rafting trip across “Tom’s Lake.” The trip concludes with passages filled with “goo,” more beautiful crystalline rooms, and then ascending ladders to sunshine and showers.
Participants must be at least 16 years old, and minors must be accompanied by an adult. Trip time varies depending on the number of participants and ranges from 2-1/2 to a maximum of 4 hours.
