Inca Stairs
Machu Picchu, Peru
At Machu Picchu, there’s 600 feet of steep, slippery and cloud covered granite rocks, that were carved by the Inca over 500 years ago.
The climb is limited to only 400 people per day and there’s chains in some of the worst parts, but the majority of the climb is a sheer, damp wall on one side and a straight drop into the Urubamba river on the other.
