Lewis & Clark Caverns State Park

Lewis & Clark Caverns State Park developed around the unique geologic feature: a cave carved from the Madison Limestone Formation.  Though Native Americans must have known about the caverns, the cave did not become well known until two ranchers noticed it in November of 1892.  With Civil Conservation Corps development, the site was deeded by the Northern Pacific Railroad to the state of Montana to become its first state park.

Today visitors explore the most highly decorated limestone caverns in the northwest on an informative two-hour guided tour. Cave passages are lined with a variety of vibrant stalactites, stalagmites, columns, helictites, flowstone ribbons and popcorn. 

Learn about geologic development and the history of early exploration; gain insight into the delicate ecology of this fabulous underground!

Non-service animals are not allowed in the caverns so the park provides spacious, shaded kennels for pets for the duration of the tour length.  Guests make check out the free facility as they purchase tickets at the ticket booth.
