The Mist Trail (Vernal and Nevada Falls)

This is Yosemite's signature hike. While many of Yosemite's trails are popular due to having a single spectacular destination, the Mist Trail has fabulous views scattered all along it, beginning at the bridge overlook, progressing to two unforgettable waterfalls that fall a combined total of more than 900 feet (270 meters), and ending with perhaps the most striking of all: the view of Nevada Fall, Liberty Cap, and the back of Half Dome from the Muir Trail return segment.
