I visited Cusco, Peru nearly two years ago but somehow never heard of the Rainbow Mountains while I was there. These skittle-looking ranges also called Vinicunca, are a three-hour ride outside the Peruvian city. The red, yellow, purple, and greenish hues are a result of leftover mineral deposits from ice sheets that once filled the area. It looks like I’ll have to make a second trip so I can hike this!
