It is formed in Mesozoic marble (metamorphosed limestone).[3] Regular tours of the cave are given by a licensed guide company from the last Friday in April to mid November.[4] It is a cave with many varieties of natural speleothems, including rare "shield" formations. Boyden Cave or Boyden Cavern is located in the deepest river cut canyon of the United States, the 8,200-foot (2,500 m) deep Kings Canyon.[citation needed] The cave entrance lies beneath the 2,000-foot (610 m) high marble walls of the famous Portals of the Kings,[5] near the Kings River.

The tour includes the Pancake Room, a stalactite group called the Upside Down City, and a flowstone formation called Mother Nature's Wedding Cake. In the Bat Grotto bats spend summer days sleeping. The Drapery Room contains curtains, soda straws and helictites. The tour ends at a small subterranean stream. 0.63 miles (1.01 km) of the cave have been mapped.[3]
