Cave tours and above-ground activities
Moaning Caverns offers two distinct cave tours, plus an outdoor hatchet-toss activity.
The Spiral Tour visits California’s largest single cave chamber. It descends 235 steps to a depth of 165 feet, including a 100-foot spiral staircase with 144 stairs, then returns up the same steps.
Built in 1922 from scrap metal from a World War I battleship, the staircase is a notable part of the route. The tour is available year-round and involves moderate exertion.
The Expedition Crawling and Spelunking Tour goes into undeveloped cave areas without lights, stairs, or walkways. Participants use lighted helmets and move by climbing and belly-crawling, so it calls for substantially more physical effort than the staircase route.
Hatchet toss is an outdoor activity. The operator advises against carrying infants in backpacks on the Spiral Tour because low ceilings occur along the route.
Choosing an activity for your visit
The Spiral Tour suits visitors who can manage a steep stair descent and the return climb, while the Expedition Tour is a strenuous option for eligible participants.
For the Spiral Tour, account for the full route: it includes 235 steps down and back up, and the operator does not recommend it for people who are claustrophobic or afraid of heights. Wheelchairs and strollers cannot negotiate the stairs. Consider these limits when deciding who in your group can take part.
The Expedition Tour has a minimum age of 12 years, and minors must be accompanied by an adult. It is physically demanding; people with heart or lung problems, pregnancy, impaired mobility, or excessive weight should not attempt it. Allow half a day, though the tour’s duration varies with group size and abilities.
