Atacama Desert, Chile — It's dry, barren and sparse. The otherworldly landscapes of northern Chile's Atacama Desert could easily be from Mars.

It is the driest desert in the world outside of the polar regions, and its 40,500-odd square miles of red and burnt-orange plains stretch as far as the eye can see.

The drive through the desert marks a stretch of the Pan-American Highway, a network of roads measuring around 19,000 miles in total; an admirable notch on any road-trip fiend's travel belt.

The lunar-esque landscape has been used by NASA for testing martian rovers, while its smooth sandy dunes draw surfers looking for a different kind of wave. By night, the sky is a kaleidoscopic wonder of constellations and attracts many a stargazer.
