Space travel doesn't yet allow for planet-hopping, so to see a place that is truly alien-looking should be on any traveler's bucket list. Personally, I suggest heading to Bolivia, where you'll find Salar de Uyuni, the largest salt flat on Earth. Twelve-thousand square kilometers of the smoothest, most reflective land on the planet, rich in gypsum, lithium and halite--and when it rains, the entire plain mirrors the sky. What's not to love about that? Check out the beautiful photo essay on Kuriositas. Link
