Mirror of the Earth
Salar de Uyuni in Southwest Bolivia, the largest salt flatland in the world at 4,086 square miles, is so extremely flatty that space-faring satellites use it for atmosphere calibrations. As detailed in these pictures, Salar experiences an annual flooding producing a thin sheet of highly reflective water that seems to mirror the sky. I want to go to there.
