National Christmas Tree dazzles

On the White House Ellipse, the National Christmas Tree will dazzle after the Obama family turns on the holiday lights on December 9th. The tree will be re-lit from dusk to 11pm each night, and there will also be free nightly performances through Jan. 1. Beautifully decorated trees will also be on display at The U.S. Capitol and Union Station.

For a little outdoor fun, the National Gallery of Art Sculpture Garden offers ice skating against the backdrop of magnificent sculptures and warm treats at the Pavilion Café (mid-December - mid-March). Or, grab a cup of hot cocoa and browse the kiosks filled with local artists’ creations at the Downtown Holiday Market along F Street between the National Portrait Gallery and the International Spy Museum.
