Lewis & Clark Caverns State Park

Discover one of the most highly decorated limestone caverns in North America.
Camp, hike and experience amazing geologic wonders at Montana's first and best-known state park.

About the Park

Lewis & Clark Caverns State Park features one of the largest known limestone caverns in the Northwest. Cave Tours are by guided tour only and will be offered May 28 – September 30th.  Tickets will be available daily only on site from 9 am through 4:30 pm; no reservations except for groups of 15 or more or educational groups.  Two tour types, the Classic Tour and the Paradise Tour will be offered.

Extra precautions are being taken for the park’s bat populations.  While White Nose Syndrome (a fungal disease that affects bats but not humans) has reached Montana, Lewis & Clark Caverns State Park staff strive to decrease additional stressors that might affect bats such as exposure to Covid-19.  Any visitor choosing to take the Classic Tour of the Cave will need to bring and wear a face mask just in the areas where the bat colony resides.  Those needing to go mask-free can still see the cave by taking the Paradise Tour that visits portions of the cave where bats do not live.

Lewis & Clark Caverns State Park also features camping and trails to hike or bike, a state-of-the-art visitor center, interpretive displays, a gift shop, food and beverage concessions, amphitheater, and interpretive events presented during the summer months.

The park has a large campground with 40 campsites, a tipi, and three cabins, which you can reserve online, and a group camping area, which you must contact the park to reserve. There is a $5 charge to use the dump station.

The site encompasses 3,015 acres. The entry area is at an elevation of 4,300 feet and the caverns area is at an elevation of 5,300 feet.

Help us conserve the bat population at Lewis & Clark Caverns State Park. White nose syndrome is a fungal disease, well established in the eastern portion of North America and recently found in the west. It does not affect humans, but has proven lethal to bats. If you have been to a cave or mine in the past two years, do not wear the same clothing, shoes or accessories as you wore there on our caverns tour. If it cannot be avoided (for example, eye glasses or shoes) please contact park staff the day of your visit in order to obtain a disinfecting wipe.

Social distancing is still required per the Governor's statewide directive to reduce spread of COVID-19. Stay safe!
