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 travelled 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 Kings Canyon 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 complemented 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 the Taco Shells, Baby Elephant & Mom stalagmites, and Christmas Tree. There is also a subterranean stream and many other unique features.
