LUCMABAMBA TO AGUAS CALIENTES, PERU - JULY 2007: The trek ascends the Patallacta pass (2700m) while still in the cloud forest, Lucmabamba Peru, 01 July 2007. We see young trekkers travelling on a budget trek down to Aguas Calientes on their way to see Machu Picchu. They are depicted as they see the first view of the back wall of the famous site. The trek continues down hill to the hydro-electric plant and man made-waterfall until the group comes to the train station from where they take a 30 minute ride to the town of Aguas Calientes. Later that day we visit Machu Picchu and see the ruins under a late afternoon sun. That night there is a full moon and we photograph Macchu Picchu under the moonlight in what must be a timeless centuries-old scene. The next morning the group walks around the ruins for an hour and witnesses tourists groups of all nationalites interacting around Macchu Pichu. Finally the group takes a Cuzco bound train on their way home. (photo by Brent Stirton/Getty Images.)
