Boyden Cave

Boyden Cave is a show cave in Kings Canyon featuring an extensive network of marble passages filled with stalactites, stalagmites, flowstones, and shield formations. The underground chambers display mineral deposits shaped by water and geological processes over millennia.

The cave was discovered in the early 1900s and gradually developed as a public attraction. It has since become a regular destination within the Sequoia National Forest area.

The cavern tours incorporate geological education, explaining the formation processes of various mineral deposits and the natural forces that shaped the underground landscape.

Access to the cave requires climbing a steep trail beneath tall marble walls. Visitors should wear sturdy footwear, bring a jacket, and expect cool temperatures inside.

The cave entrance sits beneath 2,000-foot marble walls called Kings Gates, requiring visitors to climb a steep trail for access to the underground chambers.
