Alexandria Tree Lighting

For a charming small-town feel (and none of the National Christmas Tree gridlock), head to Market Square across from Alexandria City Hall. Santa will make an appearance, leaving behind his reindeer in favor of the King Street Trolley.
National Menorah

The Hanukkah celebration takes place on the Ellipse with a 30-foot-tall menorah. Speakers and musical performers take the stage before the big moment when the first candle begins to glow.
National Harbor Light Show

The LED tree is more tech than tinsel, putting on a flashing spectacle every night set to music by the US Air Force band. Saturdays at 5:30 pm, fireworks accompany the display.
