One of Yosemite's oldest historic trails (build 1873 to 1877), the Yosemite Falls Trail leads to the top of North America's tallest waterfall 2,425 feet (739 m) above the valley floor. Do not stray off the marked path, as you will find steep drops adjacent to the tail. Enjoy spectacular view from Columbia Rock located one mile (and dozens of switchbacks) from the trailhead.
