Red Mountain Mining District lies between Ouray and Silverton on Highway 550 (better known as the Million Dollar Highway). County Road 31 exits off the highway, threads through the mountinous district, runs parallel to the highway, and eventually dumps you back on Highway 550. If you stop at the Scenic Overlook above the Idarado Mining Complex, you will be looking across at the Red Mountain Mining District. See those tiny 4x4s waaaay over there driving around? That can be you.
