My grand teens were "meh, another pool" ... unseen until you peak the ridge of the hill and get far along on the boardwalk ... you turn a corner and kapow ... this thing is bigger than three football fields and the colors are staggering brilliant. This is clearly the one must-see spot in Yellowstone.

Let's face it, natural phenomena's like this are wonderful to see. It was a most pleasant walk and shouldn't be missed.

We came in late Sept and the place was swarming with people and parking was a headache esp. if you came in mid/late morning and early afternoon when tour buses flood the place and tourists coming from West Yellowstone. We were not aware of the trail that would give you a top down view of the pool which by the... More

The boardwalk walk to the Spring was nice, but with a name like "Prismatic" I was expecting more color. Well worth the walk, though.

Must see of Yellowstone. You will probably have seen it hundreds of times in photographs of the park, but still it is breathtaking when you see it live. Such a colorful place is probably unique in the world. Don't miss it!! It is worth walking 1 mile from Fairy Falls Trailhead and climbing up the hill to get the best... More

It is my favorite attraction in Yellowstone. The rainbow colors formed by the bacteria and the geothermal activity is very beautiful!

This became the highlight of the park for us. The boardwalks provide an up close means of viewing the spring, and the colours are incredible. In your approach to it, you may notice the steam reflecting the colours. The air / water temperature battle obviously produces a lot steam, often obscures close up views, but every now and again a...

this was the only place where the tour buses just kept coming. On two occasions people literally ran into me - one even pushed me out of the way to get a picture. People were not taking in the sight but were just looking at it through the camera. When we were there - October - because of the heat... More
