"This is a breathtaking site that's stunning in its complexity," Cohen says. Machu Picchu, a stone-bordered Incan citadel sitting high in the Andes Mountains in Peru, gets much deserved praise. And while the photos you've seen of this magnificent attraction may have tempted you to book a flight, you've probably also asked yourself if it was worth the strenuous hike to get there. To put it simply, yes it is. The pictures don't do this place justice. If you don't have time to embark on a multi-day trek, opt to take a bus or train to the top.
