Event Details
Main Street Monster Mash is Downtown Nashua’s community trick-or-treat event, welcoming families for an afternoon of Halloween fun right on Main Street.
During the event, Main Street is filled
with costumed families visiting participating businesses for
trick-or-treating in a safe, walkable environment. Storefronts become
part of the experience, with many businesses decorating, dressing up,
and engaging directly with the community. A curated spooky soundtrack
plays throughout the district, creating a cohesive and immersive
atmosphere that brings the entire street to life.
In addition
to trick-or-treating, the afternoon features a variety of
entertainment and interactive elements designed to make the
experience feel special and memorable. In 2025, attendees enjoyed a
surprise live performance from ActorSingers, adding an unexpected and
energetic moment to the day. The event also introduced the
Howl-O-Ween Parade, presented by the Humane Society for Greater
Nashua, where four-legged participants showed off their costumes and
competed for prizes. This addition quickly became a crowd favorite
and added another layer of fun for both participants and spectators.
