Yosemite is one of the most magical place in California, especially in the spring when the waterfalls are flowing in full force. Upper Falls: The 1,430-foot (440 m) plunge alone is among the twenty highest waterfalls in the world. Trails from the valley floor and down from other park areas outside the valley lead to both the top and base of Upper Yosemite Falls. The upper fall is formed by the swift waters that hurl themselves over the edge of a hanging valley in a spectacular and deafening show of force. It was a real challenge to wring the waters from the parallel linear cliffs of Yosemite.
