Machu Picchu was a long time coming for me. I spent about 3 weeks in Cusco previously but it was closed that entire time because of mud slides that occured in the rainy season. I was able to pass back through Cusco after leaving Bolivia so that I could finally see the famous site. It was well worth it!
Right up there in the clouds!
I climbed up Waynapicchu, the tallest hill nearby Machu Picchu. It was quite a climb but from the top I got some amazing views of the ruins.
