Yosemite National Park announces a new program for the Horsetail Fall event taking place from February 12-26, 2018. This program has been created to improve the overall visitor experience to view the natural Horsetail Fall phenomenon that occurs each year in mid-February when the sun’s light at sunset causes the waterfall on El Capitan to glow like it is on fire. https://www.nps.gov/yose/learn/news/yosemite-national-park-announces-pilot-program-for-horsetail-fall-event-february-12-26-2018.htm
