No matter how many places you go, Nazca lines (or Nasca) the weirdest and the most perplexing sight in the world. These figures were drawn by Nazca tribes around the time of the birth of Jesus Christ, and sometimes ranging over six hundred feet wide. The wicked part is you can not see what it is from the ground, you can only make out the figures when you fly above the ground!!
So all the pictures below were taken when flying over it (You can click on the picture to get a bigger view)
A monkey spanning atleast 450 feet wide:
A humming bird
And this is perhaps the most weirdest of them, it looks like an astronaut with one finger pointing to the sky, and the other pointing to the ground. It is the most goosefleshing when you fly above it and you feel like the drawing is conveying a message to YOU.
Here is a map of all the other figures and their locations. You are typically handed one of these when you board the aircraft.
So yeah, all you need to do is just fly over to Lima, Peru and pay a small fee to look at it from above!
