The Vinicunca mountain, aka Montaña de Siete Colores (Mountain of Seven Colors), sits pretty way up in the Peruvian Andes, where it was discovered about five years ago and is now a popular destination for tourists—though the trek to reach it is notoriously daunting. If you do survive the arduous hike and uncomfortably high altitude, you’ll discover a breathtaking natural wonder: thick rainbow stripes seemingly painted into the mountainside, thanks to artfully placed mineral deposits over millions of years.
