The most entertaining way to relive the halcyon days of the Old West is to take a ride on the Durango & Silverton Narrow Gauge Railroad, a nine-hour round-trip journey along the 45-mile railway to Silverton. You'll travel in comfort in lovingly restored coaches or in the open-air cars called gondolas as you listen to the train's shrill whistle as it chugs along. On the way, you get a good look at the Animas Valley, which in some parts is broad and green and in others narrow and rimmed with rock. The train runs daily from early May to late October. A shorter excursion—to Cascade Canyon, 26 miles away—in heated coaches is available in winter. The train departs from the Durango Depot, constructed in 1882 and beautifully resored. Next door is the Durango & Silverton Narrow Gauge Railroad Museum.
