Ponder The Nazca Lines
Ticked off
What it is
The Nazca Lines are giant geoglyphs etched into the desert more than 1,500 years ago, including a hummingbird, monkey and spider.
How to do it
Small planes fly over the lines from Nazca or Pisco airports. There's also a viewing tower by the Pan-American Highway.
Top tip
Skip breakfast before the flight; the tight turns can upset stomachs.
My experience
Ticked off, but the full story is still to be written up.
