Grand Prismatic Spring, Yellowstone National Park

4.7
#3 of 85 in Parks in Yellowstone National Park
At nearly 113 m (370 ft) across and 37 m (121 ft) deep, Grand Prismatic Spring holds the title of the largest hot spring in America and one of the largest in the world. A premier attraction at Yellowstone National Park, the spring's fame traces back to early explorers and fur trappers who first noted it in the early 1800s. The boiling pool constantly steams and bubbles, with its vivid, rainbow-like appearance--the result of pigmented bacteria. To get a close-up view, walk along the park's boardwalk, which leads to a route close to the water's edge. Stay on the path, as the high temperatures of the pool can be dangerous.
