What is Yosemite ‘Firefall’?

Yosemite Firefall is a natural phenomenon that occurs annually in Yosemite National Park in California, United States. The Firefall appears when the setting sun illuminates the Horsetail Fall, a seasonal waterfall that flows from the El Capitan granite cliffs in Yosemite Valley. The light from the sun causes the water to glow and appear as if it is on fire, creating a spectacular visual effect. The Firefall is typically visible in late February or early March and attracts many visitors to the park each year.
