- Part of the historic Inca highway system (Qhapaq Ñan), the Inca Trail to Machu Piccu is one of the most important South American trekking routes. Along the hike, you can see several gorges and streams that originate from glaciers. There are twelve archeological monuments along the trail, such as Qoriwachayrachina, Patallaqta, Runkuraqay, Sayacmarca, Phuyupatamarca, Intipunku, Intipata, and Wiñayhuayna. The starting point of the trip varies according to the trail you wish to take. The most popular route starts around kilometer marker 82 of the railroad Cusco – Machu Picchu (40 km / 25 miles from the citadel itself). Another possibility, shorter in time, is called the Sacred Trail, and begins at kilometer marker 104 of the railroad.
