Find games, a costume contest with $18,000 in prizes, a costume parade, and a huge carnival while raising money for the Samaritans! The Boston Monster March is a Halloween charity walk with a separate
costume contest and parade just for children! The 1/2 mile walk takes
just a half-hour and loops around Boston City Hall Plaza without
crossing any streets. It ends before sundown, but you are welcome to
stay through the evening for more vendors, food festival, the adult costume contest and walk, and live music. Check the website before attending for possible rain cancellation.
