3001 Connecticut Avenue NW
Head to ZooLights at the National Zoo for a wildly vibrant display of LED Christmas lights (a half-million of them!), along with activities like Snow-less Tubing and special themed nights like BrewLights (Nov. 29). The kids will love the National Zoo Choo-Choo (a train ride through the Great Cats exhibit), while the big kids enjoy spiked hot chocolate and live music. ZooLights is closed on Dec. 24-25 and 31.
