GRAND CANYON OF YELLOWSTONE
Sunrise at the Grand Canyon of Yellowstone is the most breathtaking view I've experienced while I was in Yellowstone. The neutral hues of the canyons and mist from the waterfalls during sunrise felt enigmatic. It is located 38mi (61km) from the west entrance. You can also find the longest undammed river in the United States here; The Yellowstone River.
There are several ways to see the Upper and Lower Falls.
If you're up for it, you can hike the following:
