High Sierras, California

Boyden Cavern, Giant Sequoia National Park

Boyden Cavern is located in Kings Canyon, Giant Sequoia National Monument, one of the most beautiful and spectacular places on earth. Fortunately it's not as well known or traveled as Yosemite or the Grand Canyon, making for a more peaceful and less disturbed feel.

Please be aware that to get to Boyden Cavern, you must drive into Sequoia National Park where the National Park Service charges each vehicle $20. This fee is not associated with Boyden Cavern. You will still have to pay an admission price at the cavern.

Boyden Cavern lies beneath the massive 2,000 foot high marble walls of the famous Kings Gates. It is a magnificent cavern with many varieties of natural speleothems, including rare "shield" formations. Visitors are delighted to find that spectacular beauty above ground is complimented by natural beauty underground.

The Walk Tour

This popular 45-minute tour is suitable for the entire family, from kids to senior citizens. The tour begins with a steep five-minute walk to the cavern entrance and from there visitors travel deep within, where the temperature is a constant 55oF. Groups follow a well-lighted and handrail equipped trail as guides point out many natural varieties of formations. Reservations are not required. Tours leave approximately every hour on the hour. For safety reasons, we do not allow children to be carried in backpacks on this tour. Small babies in front packs/slings are okay.

Popular features include The Pancake Room, a stalactite group called the Upside Down City, the Bat Grotto where bats spend summer days sleeping, and a flowstone formation called Mother Nature's Wedding Cake. The Drapery Room contains large drapery stalactites, long soda straws and twisting crystalline helictites. Speleothems have developed to resemble familiar objects, as with the Taco Shell formations, the Baby Elephant & Mom stalagmites, and the Christmas Tree. There is also a subterranean stream and many other unique features. New this year, by reservation, 1/2 and full day rappelling tours are available, as well as 1/2 and full day canyoneering tours with lunch and equipment supplied. These advanced adventure treks are available for all ages and experience levels. Call 559-338-0959 for more information or emails us at This email address is being protected from spambots.
