Sentinel Falls is another tall waterfall in Yosemite that you won't see, unless you are there in the spring. If you park alongside the road at Four Mile trailhead, you'll probably be the only person looking at Sentinel Falls, as everyone else will be staring across the valley at the more impressive Yosemite Falls. It is quite different from the others in Yosemite Park, as it tumbles 2000 feet down Sentinel Rock. Unfortunately, there are no trails to the base of the falls. You can get to it from the Sentinel Dome trail head. *Elevation: 5,360 feet
