Durango is one of the most interesting small towns in Colorado. Not just for retirees, but also for young people (average age is 29). Located in the southwestern part of the state, Durango has convenient access to at least 5 major ski areas including Purgatory (about 25 miles away). The Animas River, a gold medal fly fishing stream, flows through the center of town. The town is world famous for every kind of outdoor recreation including mountain biking, hiking, kayaking, and golf. Because it is an old railroad and mining town, it has an interesting downtown. Durango is a college town, thanks to Fort Lewis College. The population is over 18,400 and growing fast. Photo of downtown courtesy of Wikipedia and Sascha Brück.
