The trip to Machu Picchu can be done several different ways. One of the most popular and spectacular is the Inca Trail. You traverse the Andes, passing archaeological ruins, rivers, terraced valleys, snow-capped peaks, cloud forest, and a wide array of flora (including numerous varieties of orchid) and bird life. Not only is this a good walk, but it also allows you to get a better understanding of the Inca world en-route to Machu Picchu.
