Trick or Treat on 1st Street

Join us for Downtown Mount Vernon’s Annual Trick-or-Treat, where families come downtown for a fun and safe alternative to neighborhood trick-or-treating. Bring your costumed kiddos (and selves!) and stroll around to grab goodies from participating businesses on Friday, October 31, 2025. Enter into our photo costume contest by tagging @mountvernonwa on Instagram or Facebook, winner gets a delicious downtown prize! 🙂 No worries if you can’t get there right at 4, trick or treating goes all the way until 6 so show up whenever you can!
