One of Yosemite's oldest historic trails (built 1873 to 1877), the Yosemite Falls Trail leads to the top of North America’s tallest waterfall, which rises 2,425 feet (739 m) above the Valley floor. This trail starts near Camp 4, along the Valley Loop Trail, and immediately begins its climb, switchback after switchback, through oak woodland. You will begin to climb above some trees and into exposed plateaus that offer you a glimpse of what's to come: great views of Yosemite Valley and its many iconic landforms. Do not stray off of the maintained path, as you will find steep drops adjacent to the trail.
