Or you can get there by steam train. The iconic Durango & Silverton Narrow Gauge Railroad offers 3 1/2-hour rides from the historic railroad town of Durango. The temperature gradually drops as the train ascends to Silverton. With the Animas River meandering below and forested peaks all around, keep an eye out for elk, black bear and other mountain wildlife. Once you’re in Silverton (population: about 600), there’s mining heritage and a charming Old West main street to explore.
