One of the most spectacular sights in Yosemite is Yosemite Falls which can be seen from a number of spots on the Yosemite Valley floor and makes for breath taking photos. The Yosemite Upper Falls drops 1,430 feet (440 meters), and just the Upper Falls section ranks as a top 20 waterfall in the world. There are hiking trails from the valley floor to both the top and base of Upper Yosemite Falls. Yosemite Upper Falls usually has water flow year round, but there have been occasions when it has gone dry in the past.
