Horsetail Fall flows over the eastern edge of El Capitan in Yosemite Valley. This small waterfall usually flows only during winter and is easy to miss. On rare occasions during mid- to late February, it can glow orange when it's backlit by sunset. This unique lighting effect happens only on evenings with a clear sky when the waterfall is flowing. Even some haze or minor cloudiness can greatly diminish or eliminate the effect. Although entirely natural, the phenomenon is reminiscent of the human-caused Firefall that historically occurred from Glacier Point.

Viewing Horsetail Fall in Late February

Due to the popularity of the event, restrictions will be in effect from February 13 through 27, 2020 daily from noon to 7 pm. To view Horsetail Fall, park at Yosemite Falls parking (just west of Yosemite Valley Lodge) and walk 1.5 miles (each way) to the viewing area near El Capitan Picnic Area. Vault toilets, along with trash and recycling dumpsters, are available at the picnic area. Northside Drive will have one lane closed to vehicles so pedestrians can walk on the road between the viewing area and Yosemite Falls parking. Bring warm clothes and a headlamp or flashlight. Parking, stopping, or unloading passengers will be prohibited between Camp 4 and El Capitan Crossover. Vehicles displaying a disability placard will be allowed to drive to El Capitan Picnic Area and park in turnouts on the north side of Northside Drive.

Southside Drive will be open to vehicles, but parking, stopping, and unloading passengers will be prohibited between El Capitan Crossover to Swinging Bridge Picnic Area. Pedestrians will also be prohibited from traveling on or adjacent to the road in this area. From Cathedral Beach Picnic Area to Sentinel Beach Picnic Area, the area between the road and the Merced River (including the river) will also be closed to all entry.

El Capitan Crossover (the road connecting Northside and Southside Drives near El Capitan) will be open to vehicles, but parking, stopping, and unloading passengers will be prohibited.

No permit or reservation is required to view Horsetail Fall.

Why are these restrictions in effect?

Historically, the sunset backlight on Horsetail Fall was little known. However, in recent years, visitation around this event has increased dramatically. For example, on February 22, 2019, over 2,000 visitors viewing Horsetail Fall gathered in areas mostly lacking adequate parking and other facilities. Visitors spilled onto riverbanks, increasing erosion and trampling vegetation. As riverbanks filled, visitors moved into the Merced River, trampling sensitive vegetation and exposing themselves to unsafe conditions. Some undeveloped areas became littered with trash, and the lack of restrooms resulted in unsanitary conditions.
