World Museum of Mining

155 Museum Way, Butte, MT 59701 - United States





Open April through October, the World Museum of Mining is one of the few museums in the world located on an actual mine yard - the Orphan Girl.

This 22 acre museum exhibits more than a century of American history and brings it to life. Explore more than 50 structures, ranging from the 100 ft. high head-frame to the many buildings of Hell Roarin’ Gulch, a turn of the century mining town.

Our displays and exhibits focus on mining and the related culture and ethnic groups that made Butte, MT their home.

The World Museum of Mining offers two underground mine tours that take you into the depths of the Orphan Girl mine. The 65 ft tour is a glimpse of the underground and takes 45 minutes to an hour. The 100 ft tour provides more in depth history and gives visitors the opportunity to see the Orphan Girl vein. The 100 ft tour takes approximately 1.5 hours. Get fitted with a miner’s hard hat and light to experience life underground! Space is limited and reservations are required. Underground tours are an additional cost. From time to time weather conditions affect our ability to offer all available services.
