Plan to be on the tour at the Argo for an hour and a half to two hours for the full experience. Each professionally guided tour of the Argo Mill and Tunnel takes approximately 1 hour and 15 minutes. A gold panning lesson and experience, which lasts about 20 minutes, is also included with every Argo Mill and Tunnel tour.
Following the tour of the Argo Mill and Tunnel, each tour guest will get a gold panning lesson using a sample with real gold ore. You keep what you find!
Learn about the history behind the tunnel, mill, and mines.

The Argo Mill Tour is a favorite educational and entertaining outing for many schools who bring students from all grade levels, including engineering students and professionals from all over the world. Educators can use resources from the Minerals Education Coalition’s (MEC) in partnership with the Mighty Argo to provide a rich, hands-on historical experience. Because of the historic significance and impact that the Argo Mill and Tunnel played in local and state mining history, it was placed on the National Historic Register by the Department of the Interior in 1978.
We look forward to accommodating your group – call for discount rates and other information.
For the safety and protection of our young visitors, all children under 40 inches tall on the Argo Mill Tour must be accompanied by an adult who holds their hand or carries them through the tunnel.
