A group on a guided tour inside the Argo Mill

One Guide, One Mountain of History

The Argo Tunnel ran 4.16 miles under Idaho Springs and drained the mines above it. The mill below sorted what came out. A guide walks your group through the whole route the ore took — about an hour and a half, with stops inside the tunnel and on the mill floors.

Every tour ends at the panning troughs, and everyone takes home real Colorado gold. It suits club outings, reunions, company days and coach tours, and it runs whatever the weather is doing.
