I am out of the clouds and off the trail, considered to be one of the toughest treks in the world, the Inca Trail. With a four day hike and walking 48 km or 30 miles at altitudes ranging from 8,000 feet to 13,900 feet or 2,500 meters to 4,200 meters, it is grueling and something that brings one to understand that the Incas were one tough group of people. They built 5,000 km of trails all from grainte blocks from the years 1200 to 1600 before the Spanish over threw their kingdom. What the spaniards didn't find was Machu Picchu as well as many other sites.
Take a look at these videos to get an understanding of the trek and the terain contained in the Peruvian Andes.
