Llamas, Incan Ruins, and the Joy of Volunteering!
Probably the most fascinating of all of this is, of course, Machu Picchu. Only when you go there and see it for yourself will you realize how majestic it is, and fully understand why it is one of the seven wonders of the world. Not only are the ruins themselves amazing, but the views from being up in the mountains of the other mountains and of the rivers running through so far below you will take your breath away.
