Witnessing the Fire Falls in Yosemite Park is one of a kind experience because this natural phenomenon occurs only in February every year. So if you happen to be in the park in February, try to find the Horsetail Waterfalls set in the Yosemite Valley. The visual perception of a fire falls is created by the sun that illuminates the fall from behind. Don't worry if you don't manage to see this spectacular optical illusion though - the park itself is an absolutely marvelous place to visit anyways.
