The Monster Mash Howl-o-ween on Main Street

Join us in Downtown Nashua for a spooktacular celebration on Main Street! The Monster Mash Howl-o-ween brings together families, friends, and four-legged companions for an afternoon of festive fun. Kids can enjoy trick-or-treating with our downtown businesses in addition to live music, costume contests (for kids and pets!), and a special surprise from the ActorSingers! Trick or treating begins at 11AM and the fun kicks off at 11:30AM with our Pearl Streets Howl-o-ween Puppy Parade in partnership with the Humane Society for Greater Nashua. Noon will be our special surprise. Trick or treating will happen until 1PM. Whether you’re showing off your best costume, shopping local, or just soaking in the fall spirit, Monster Mash Howl-o-ween is the perfect way to celebrate Halloween in the heart of the city.

While you’re here, don’t forget to vote for your favorite Downtown Scarecrow! The top five scarecrows will be featured on our website for the next year, complete with the organizations’ logos and links to their websites — a chance for them to shine long after Halloween is over.

Our friends at the Nashua Public Library are having their own Halloween party right after 10AM Storytime! Double your fun and visit the NPL before heading to Main Street!

Don’t have a costume? Don’t worry! Our favorite spooky nonprofit, SCARE NH, will be at the Library on October 11th with a selection of costumes to choose from!

A huge thank you to ActorSingers and Human Society for Greater Nashua (HSFN) for co-sponsoring this event with us!
