"Timing is everything if you want to fully appreciate Yosemite Falls, one of the most popular attractions in the park. Fed by melting snow in the high country, the falls begin booming around April but, by the end of summer, are a mere trickle of their former selves. Together, the three sections make up one of the highest waterfalls in the world. The 320-foot Lower Fall is the most accessible (just follow the signs on the footpath at the back of the Yosemite Valley Lodge), while the middle section is visible only from a few spots on the steep Yosemite Falls trail. The true showstopper, however, is the 1,430-foot Upper Fall, which plunges from a granite saddle at the mouth of a meadow. Trails from the valley floor afford spectacular views, but you can also see it from the Swinging Bridge and the field on the south side of the Majestic Yosemite Hotel."
