When this is the first thing you see while waiting in the car at the Yellowstone entrance, you know it’s going to be a good day. We also saw black bears, bison, antelope, coyote, pica, and much more.
The scenery is such a marvel. We walked about 2 miles throughout the Norris Geyser Basin. The brilliant sunshine brought out colors of the algae in the hot waters.
Our most challenging part of the day involved a hike to the rim of the lower falls of the Yellowstone River. It included a 600 ft descent via a trail that switched back and forth more than 10 times. Of course, that meant you had to ascend the same trail. We are in good shape and made it up easily. Others were not looking so good.
Once at the bottom of the trail, we got this view of the rapidly flowing river as it plunged 308 ft to the floor of the canyon. The rainbow was a special treat.

Beautiful!
Tremendous range in your vantage point with this video. What are you using to capture the video?
The zoom on my digital Canon is 65x. I really like it. (PowerShot SX60 HS)
I don’t remember ever seeing these falls. The fact that you’re hiking rather than only driving from scenic overlook to scenic overlook parking lot certainly means great images.
We’ve avoided many crowded spots by hiking.
