Every year 50,000 folks parade up Sixth Avenue—decked out in some of the City’s scariest, most inventive and most hilarious costumes—while numerous live bands complement the ghoulish revelry. Show up with a creative costume of your own and join the parade (but note that a costume is a must to march!), or stick to your civvies and take in the spectacle from the sidelines. Marchers line up on Sixth Avenue between Canal and Spring Streets. The parade gets rolling at 7pm and heads north up Sixth Avenue to 16th Street.
