Grand Prismatic Spring, Yellowstone National Park, Wyoming
Visitors flock to Yellowstone to witness a natural phenomenon that looks as though it doesn’t belong on Earth. Grand Prismatic is the largest hot spring in the United States and the third biggest on the planet.
But the thing that sets this captivating crater apart is not its awe-inspiring size. The colours here are eye-catching in the extreme and like something from an alien world. Like to see it for yourself? You’ll feel as though you’ve travelled to a strange and distant land.
Deep blue in the centre, Grand Prismatic’s mineral rich waters are rainbow-like — covering the full spectrum and making for a spectacular sight. Thinking about taking a quick dip? Think again. The water temperature here can reach 160C and, when Grand Prismatic erupts, it’s best not to be too close. Best experienced from a safe distance, this is an otherworldly experience that is not to be missed.
