Woke up this morning at 5:45am to hike up to Sacsayuhuman (pronounced sexy woman). It is a military fortress ruins made up of perfectly cut limestone stacked without the use of mortar. It was about a 2 hour hike in total. And the altitude definitely made things tough. The good thing about always having a camera in hand is that when I get tired and need a break, I just pretend to that I'm stopping to take a picture. No one knows I'm out of shape! Anyways, the view brings you to a looking point over the entire city. Really incredibly cool.
