There are many great places to see Christmas lights in New York City! Some of my favorites include Dyker Heights, which has hundreds of houses decorated with intricate displays, and the Bryant Park Winter Village, which has a large Christmas tree and a skating rink. The Macy's Thanksgiving Day Parade also has a wonderful display of lights during its route. For something a little different, you could check out the holiday markets in Union Square or Grand Central Terminal, which feature a variety of festive decorations and vendors.
