It doesn't get much more "iconic NYC Christmas" than the Rockefeller Center Christmas tree, towering above the ice rink below. Things get festive on December 4, when thousands of revelers will fill the area for the lighting of this signature Norway spruce. Catch holiday-themed performances from a star-studded guest list, usually hosted by NBC anchors (like Al Roker). When the switch is flipped on that Swarovski star–topped tree wrapped in 30,000-plus energy-efficient LED lights, expect plenty of "oohs" and "ahs" from the crowd. If you can't make it to the big event, you can see the tree (and snap plenty of photos of it) through January 7. For more information, visit rockefellercenter.com.
