Still chugging along is the Leadville Railroad, which can take you on a breathtaking 2½-hour trip with views of wildflowers, fall foliage, or holiday lights depending on the time of year. Combo rides include zip-lining or rafting adventures. The train leaves from Leadville's century-old depot and travels beside the Arkansas River with views of Mt. Elbert, Colorado's highest peak.
