Last year, because of the pandemic, visitors heading to Yosemite Valley to see the spectacle at Horsetail Fall, when light and water flow combine to make it look as though a river of fire is pouring to the valley floor, needed reservations. It was an attempt to keep people from crowding close together, and also an attempt to keep the work from home crowds from obliterating the place.
This year, however, no reservations are required. It’s a free for all! Wait, that’s not right. Actually, there are restrictions. The park expects the firefall to occur from February 10 through the 28th. On those days, viewing times are restricted from noon to 7pm. Of course, the spectacle takes place only at sunset, so they’re trying to keep people from massing at the viewing zone all day long.
California is having a schizophrenic winter, with gobs of rain in the fall and December, and virtually nothing since, but the waterfall is flowing, so provided there are clear skies, it should rain fire once again. More info here.
