Festivities begin at 3:00 pm and continue into the evening. Nyack’s Main Street and South Broadway will be closed for the day’s celebrations. The parade will step off promptly at 5:30 pm.Hosted by the Nyack Chamber of Commerce and the Village of Nyack, the Nyack Halloween parade is the biggest outside New York City, second in magnitude only to the Greenwich Village event ― and just as spectacular on the “wow” meter for color, pageantry and unabashed craziness!
