Description:
Moaning Cavern is home to the largest vertical chamber open to the public in California. A massive space so vast it could hold the Statue of Liberty!

Energetic cave explorers can begin this exciting expedition with a 165-foot rope rappel into the darkness of the cavern below.

Most areas are undeveloped, so there are no lights, stairs, or walkways. Instead, you will daringly explore chasms, tunnels and tight spaces by climbing and belly crawling with lighted helmets to show the way.

Guides explain the history and geology of the cavern, and discuss the explorations that have traced the cavern to its current depth of 410 feet.

The tour ends on the spot where scientific excavations revealed the bones of prehistoric people who had fallen into the cavern thousands of years ago.

Our Moaning Cavern Rappel and Cave tour was phenomenal! Not only was it thrilling and, at times, almost surreal, but our guide, Stacey was so patient and knowledgeable about the innards of the cave, she made us feel so welcomed and comfortable. The true beauty and wonder of Moaning Cavern was absolutely made possible and appreciable thanks to the fun and helpful employees and guides there at the Adventure park. We will definitely recommend the trip to EVERYONE and hope to be able to return some day to relive the experience!!!

  1. How cold is the cave?
    The temperature in the cavern is pretty consistent at 61 degrees, therefore most are comfortable in short sleeves and shorts (if you get cold easily, we recommend bringing a light jacket). Also, do keep in mind that clothing may get dirty and some minerals may not wash out.
  2. Can I bring food or drink with me in the cave?
    In a conservation effort, food and drink is not allowed in the caverns or gold mines.  It only takes a small amount of these foreign materials to make a big difference in the cavern environment and to the cleanliness of the mines.  However, if you need to bring food or drink with you for health purposes, it can be approved by your guide. 
  3. How safe is the rappelling?
    Professional rappelling equipment is provided as well as a trained expedition guide. The rappel is easy enough to not require any previous experience. However, it is a high adventure activity in a natural environment.
