1. Kiener Plaza: Watch the Official Display
Kiener Plaza is the published location for the free Winterfest Neon Nights celebration and its 8 p.m. fireworks. The organiser describes the display with views of the Gateway Arch, making this the clearest choice if fireworks are your priority. Expect a festive crowd, DJ, live music, fire dancers, and character visits before the show. The plaza is in downtown Saint Louis, close to the Arch landmark. The fireworks are scheduled for 8 p.m., not midnight, so plan your evening around that earlier show.
