As if Machu Picchu weren’t already shrouded with mystery, the area immediately surrounding it is home to two little-known waterfalls. First is an unnamed cascade at the end of a walking trail on the grounds of the Inkaterra Machu Picchu Pueblo Hotel, in Aguas Calientes; guides lead meditative twilight walks to the falls and point out pre-Inca petroglyphs along the way. Then there are the secluded Mandor falls, midway between the hotel and Machu Picchu. It’ll take a half-day to hike there, but the trail is home to speckled-faced parrots and green jays, and Inkaterra’s guides will gladly lead the way.
