Grand Prismatic Spring, Yellowstone National Park

4.6
#3 of 64 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.

  • Take pictures in the big prism hot springs, especially from the top down. This natural landscape is not everywhere, so I think it's worth watching a good experience.

  • The Grand Prismatic Spring has stunningly vibrant colors. The last time I was there it was cloudy and mist-shrouded which only added to the mystery of this gorgeous spring.  more »

  • One of the most beautifully primordial places in the country. An essential stop for any Yellowstone tourist.
  • Beautiful place with absolutely stunning colors. The place is really well guarded and protected, and very clean. It's very nice to see that everything is done to keep this place so pure and enjoyable for the future generations. Amazing place to visit!!!
  • I had only seen the picture from above but even at ground level it is very impressive. We visited in the late afternoon and the shimmering of the light on the colors was spectacular. The walk is fairly easy even for an older person.
  • Super beautiful! There is a trail you can take where you can actually see the whole thing from above. I recommend taking that over walking the boardwalk... it's hard to see from there
  • It's amazing from google map view even...
