Located in Idaho Springs, Colorado, the Mighty Argo Mill and Tunnel is one of the most striking and prominent Heritage Landmarks in the American West. The Argo is a central character in the story of the Colorado gold-rush, and remains one of the largest, most well-preserved historic gold mills in the world.

In addition to significant updates and improvements to the heritage experience, a rich seam of new and recently entitled programming is planned, including a scenic cable car, creative food & beverage and retail offerings, public space, and unparalleled access to outdoor recreation. The Mighty Argo will fundamentally reshape the recreational and heritage offerings of this tight-knit mountain community.
