Train travel on PeruRail (www.perurail.com) is slow but scenic and more relaxing than a bus blasting reggaeton. A Pullman train ticket means more comfort, not to mention a meal and increased security. The train goes only between Cusco and Puno. It's a popular way to take in the dramatic change of scenery as you ride over La Raya Pass at 4,315 meters (14,157 feet). The trip takes about nine hours and includes a stop at the highest point. The route runs only a few days per week, depending on the season. For a full listing of PeruRail trips, check out the website. It's now possible to book online.
