Lower Yosemite Fall trailhead

Lower Yosemite Falls - Western Approach

This is one of Yosemite's most irresistible trailheads, along with Glacier Point and the Tuolumne Meadows trail to the soda springs. If you're willing to stretch the definition of "trail" to the breaking point and a ways beyond, as this website has happily done, you can throw Washburn Point in there, too.
