From Cusco, PeruRail provides passenger services on the 3 ft (914 mm) gauge Ferrocarril Santa Ana to Aguas Calientes, delivering tourists for Machu Picchu. Currently the only legal way to depart Machu Picchu from the town, Aguas Calientes, is by train. There are no roads from the town and helicopter services have been suspended indefinitely. In addition to the train, visitors can reach Machu Picchu via several inbound hiking trails, including the Classic Inca Trail from Cusco, but there is no hiking back the other way on the Inca Trail.
