Inca Trail to Machu Picchu 3,300 metres on the first day. The second day ascends over Dead Woman's pass- the highest point on the Inca Trail at 4,200 metres. This is the most dangerous point in terms of altitude sickness, however, you do not spend long at this elevation and by the afternoon you'll be back at 3,600 metres. The trail only descends from this point until you reach Machu Picchu at 2,430 metres. Inca Trail to Machu Picchu The Inca Trail to Machu Picchu (also known as "Camino Inca" or "Camino Inka") is a hiking trail in Peru that terminates at Machu Picchu. It
Machu Picchu more farmland to grow crops, and to steepen the slopes that invaders would have to ascend. The terraces reduced soil erosion and protected against landslides. Two high-altitude routes from Machu Picchu cross the mountains back to Cusco, one through the Sun Gate, and the other across the Inca bridge. Both could be blocked easily, should invaders approach along them. The site is roughly divided into an urban sector and an agricultural sector, and into an upper town and a lower town. The temples are in the upper town, the warehouses in the lower. The architecture is adapted to the mountains.
