Wearing the GoPro chesty and climbing down from Huayna Picchu (the mountain located N of Machu Picchu, and approximately 1000 feet above the ancient city). There are Incan ruins on Huayna Picchu and these were believed to serve as a post for surveillance of the surrounding Urubamba valley as well as the study of astronomy. Note the absence of serious safety provisions. This kind of hike would never be possible in the states without some serious death waiver-signing. Hike was made possible by Knowmad Adventures. Loved it.
