Los Alamos Halloweekend

The autumn season culminates in the widely anticipated Los Alamos Halloweekend, running from Friday, Oct. 30 through Sunday, Nov. 1. The flagship event, Trick-or-Treat on MainStreet, takes place on Friday, Oct. 30, from 4-6 p.m. Central Avenue in downtown Los Alamos will close to vehicle traffic, creating a safe, pedestrian-only haven where thousands of costumed trick-or-treaters can visit more than 75 booths operated by local businesses, non-profits, and community groups. In addition to candy stops, attendees can enjoy live dance performances, local musical acts, and an array of food trucks. High-tech Halloween activities at the Bradbury Science Museum and interactive stops at downtown storefronts will round out the festivities.
