Lewis & Clark Caverns State Park offers two visitor centers to orient guests to the facilities, programs, and natural options available.

The Main Visitor Center, located at the entrance of the park just off Hwy 2, targets the unique geology, flora and fauna one can experience in the 3000 acre park. It presents a meeting room, local visitor services and information as well as is the location for the management offices and headquarters.

The Cave Visitor Center, three miles at the end of the park road, focuses on the caverns with a 29 minute video, small museum, cave exploration room, and ticket booth. Across the street from this lies Montana Gift Corral, a gift shop and deli to serve the needs of all.

Both building and restroom facilities are wheelchair accessible, though cave access is more challenging.
