Horsetail Fall is a seasonal waterfall in Yosemite National Park, located on the eastern face of El Capitan. It drops approximately 1,570 feet (480 metres) in two distinct sections, making it one of the park’s taller waterfalls. Unlike Yosemite’s more permanent falls, Horsetail Fall flows only during a brief period in winter and early spring, fed almost entirely by snowmelt and rainfall. In most years, its peak flow occurs in February and March, though in dry winters it may not appear at all.
The waterfall is best known for the natural phenomenon referred to as the “Firefall,” which occurs for a short window in mid- to late February. During this period, if conditions align with sufficient water flow, clear skies, and the correct sun angle at sunset, the falling water is illuminated in orange and red hues, giving it the appearance of molten lava. This effect typically lasts for several minutes and has become a highly photographed event, attracting large numbers of visitors and photographers.
Horsetail Fall can be viewed from several points in Yosemite Valley, but the most common locations are along Northside Drive near El Capitan Picnic Area and Southside Drive east of Cathedral Beach. During the Firefall event, the National Park Service manages traffic and parking to accommodate increased visitation, and visitors are often required to walk significant distances from designated parking areas.
Geologically, the fall originates from a small drainage area on the summit of El Capitan, where snow accumulates during winter. As temperatures rise, meltwater flows over the granite cliff, creating the narrow, ribbon-like cascade. Its short-lived seasonal nature differentiates it from perennial falls such as Yosemite Falls and Bridalveil Fall.
Because of its limited flow period, Horsetail Fall is not a year-round attraction, but during its brief seasonal peak – especially during the Firefall phenomenon – it becomes one of the most sought-after photographic subjects in the park. The combination of precise environmental conditions required for its full effect makes witnessing Horsetail Fall’s fiery appearance a rare and memorable occurrence for visitors.
