One of the most popular places to see Christmas lights in New York City is the Rockefeller Center Christmas Tree. This iconic tree, which is typically 65-100 feet tall, is decorated with over 45,000 lights and crowned with a star-shaped topper. The tree is lit every year on the Wednesday after Thanksgiving, and it stays lit through the beginning of January. Visitors can also check out the ice skating rink located directly in front of the tree, which is a great way to get into the holiday spirit.
