What to know

Rainbow Falls is a historic landmark located on the north side of the JFK Promenade, approximately 700 feet east of Transverse Drive. Built in 1930, the falls were originally designed as a colorful spectacle for the public. During its opening dedication that same year, the waterfall featured a spectacular evening display using multi-hued lights to illuminate the cascading water. While the rainbow lighting is no longer present today, the site offers other visual interests. Visitors can observe folds of chert, a type of sedimentary rock, visible in the cliffs situated to the east of the falls. The water itself drops into a pool before running downhill alongside the JFK Promenade for several hundred feet, eventually draining into Lloyd Lake. In recent years, the falls have gained attention for a peculiar natural phenomenon. Visitors occasionally notice the water turning a bright green color. According to Dave Iribarne, a superintendent for the San Francisco Recreation and Parks Department, this is caused by an algae bloom. While the vibrant hue can look alarming to some, the superintendent notes that it is not harmful. Beyond its natural and geological features, the area continues to serve as a community hub. The San Francisco Recreation and Parks Department has utilized the falls as a venue for public events, such as a family-friendly celebration held in July 2024 to commemorate a new Naga installation.
