"Firefall" is a unique event where each February if snowpack levels, temperatures and weather cooperate Horsetail falls is lit by the setting sun causing the falls to glow as if they were lava. Interestingly the name Firefall came from 1872 when a hotel owner actually dumped the hot coals from a bonfire over the edge of Glacier Point to the awe of visitors in the valley below. This happened almost nightly for 25 years until the operator was banned in 1897. If you are planning on visiting be warned that it's become incredibly overcrowded. We had hoped that a covid year and the National Park limiting visitors would be a chance for fewer crowds, but no such luck. Despite the crowds it's still a beautiful site to see.
