Cumbres & Toltec Scenic Railroad
Take a day trip on the Cumbres & Toltec Scenic Railroad, an 1880s steam locomotive that chugs through portions of Colorado's and northern New Mexico's rugged mountains that you can't reach via roads. It's the country's longest and highest steam-operated railroad. The company offers round-trip train routes, several bus-and-train combinations, one-way trips, and themed rides.
