3. Grand Prismatic Spring: Wyoming, USA
Hot springs.. You might have seen plenty. But one that comes with rainbow hues? Looking like a scene ripped out of a fantasy novel, the Grand Prismatic Spring in Wyoming is the largest hot spring in the United States and is located inside the Yellowstone National Park. The peculiar thing about this hot spring is its intense and vivid colours due to a series of bacteria that grow on the edge of the mineral-rich waters of the spring. The hot spring has bright bands of orange, yellow, and green ring surrounding the deep blue waters in the spring. You’ll never see another hot spring like this one!
