Well, the easiest way to get to the Dyker Heights Christmas lights is to take the D or N train to the 86th Street station and then walk about 15 minutes to the main Christmas lights display area. You can also take a bus or taxi to the 13th Avenue bus stop and walk from there. The Dyker Heights area is also very walkable, so you can just explore the neighborhood and discover all the other festive decorations and displays along the way.
