Lehman Caves Wild Cave Tours

Lehman Caves can be explored two ways: On a tour on a paved tour route, or on the wild side. An Introduction to Wild Caving Tour is available on weekends during the summer months for small groups to explore the deep dark of Lehman Caves.

Off the paved tourist trail and away from the electrical lighting system, you will experience the cave in its natural environment. Learn how to cave safely while protecting the cave and the natural and cultural history that lies deep within.

Your experience begins at check-in at the Lehman Caves Visitor Center where you will meet your guide, go over fitness and equipment requirements, safety messages, and be fitted with provided cave gear. From there, you'll assemble as a group and journey underground, exploring the approximately 1.5miles of Lehman Caves, beginning on trail before climbing into the dark.

This tour requires bending, climbing, and is considered strenuous. Be prepared to get your clothes dirty and have fun! The tour is limited to 8 people, age 16 and older, and requires advanced ticket reservations.

Wild Caving outside Lehman Caves

Lehman Caves is the most famous of Great Basin National Park's caves, but there are actually about 40 caves in the park.

Upon completion of a Wild Cave and Karst Management Plan, seven wild (undeveloped) caves are open to recreational use in the Park under a permit system. All other wild caves are closed except to research and management uses.

How do I get a wild cave permit?
Recreational permits will be approved for those who can demonstrate cave conservation ethics and their experience with horizontal and (if pertinent) vertical caving techniques and equipment. Cave gear must be clean. If cave gear has ever been in a White-nose Syndrome (WNS) area, it is not allowed inside any GRBA cave, regardless of decontamination.

1. Permits should be applied for at least two weeks prior to the trip.
2. No more than one permit per week will be issued for each cave.
3. Each group must have a minimum of 3 people and a maximum of 6 people.
4. Each group must have all of their own gear, including helmets, lights, kneepads, and gloves.
5. All cave gear and clothing must be clean when entering the cave.

Groups may apply to enter multiple caves, as long as entry is during the open period for those caves. Cavers who qualify and are interested can contact the Cave Specialist for a permit application and more information.
