Follow the vein of gold ore one-third of a mile into Galena Mountain, and you can see and experience the operation of mining equipment in a real mine setting. The Old Hundred bores into Cunningham Gulch, just minutes from historic Silverton, in a scenic area that's easily accessible by car or RV. The 45-minute guided tour takes place in an authentic mine tram as well as on foot. Tours leave on the hour from 10 a.m. to 4 p.m. seven days a week from May 10 through October 13. Gold panning is free with the purchase of a tour ticket.
