Summer & Fall (dry season) Trail of Lights Tour : 60 - 80 Minutes Long Winter & Spring (wet season) Trail of Lakes Tour: 45 - 60 Minutes Long https://images.squarespace-cdn.com/content/v1/5a25ec5e80bd5e3db7025715/f443b907-382a-45b4-b54d-84625fe427e4/cc+spelunk+5.jpg California Cavern Tours | Official Site | Mountain Ranch, CA - Mammoth Expedition groups explore the historic "Mammoth Cave" area and “Jungle Room" by walking, crawling, wriggling, and squirming through natural passages that connect through 8 chambers. This extended cavern trip is perfect for those who desire something more than a walk, but less stamina is needed compared to the other adventures offered. All tight crawl ways and squeezes are optional. Participants must be at least 8 years old. Minors, under 18 years of age, must be accompanied by an adult. Trip time is about 2-3 hours. These tours typically open mid summer.

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 198o. Here there is mostly walking through nearly knee deep, sticky cave clay (hightop 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. These tours typically open mid summer.
