Boyden Cavern

A cave in the canyon

Boyden Cavern, nestled beneath the majestic marble walls of the King’s Gates, is currently closed for maintenance. The estimated date for its reopening is June 2024. Once reopened, visitors can embark on a guided, 50-minute walking tour through this subterranean wonder, exploring its captivating rock formations and geological wonders. Accessible from a short yet steep trail, Boyden Cavern promises an adventure suitable for all ages.

Tour information and safety

Guided tours of Boyden Cavern are conducted daily from 10 a.m. to 5 p.m. by a US Forest Service partner. We recommend wearing sturdy hiking boots and a light jacket to ensure comfort in the cave’s constant 55-degree temperature. Purchase tickets in person or from the official website at in advance.

Wildlife safety measures

In light of the threat posed by white-nose syndrome, a fungal disease affecting bats in North America, visitors are urged to adhere to strict wildlife safety protocols. Devastating bat populations in various regions, the disease poses a risk of transmission through contaminated clothing and gear. To prevent the spread of the fungus, visitors who have explored caves in other areas must refrain from wearing the same attire or equipment when visiting Boyden Cavern.
