Halloweekend in Los Alamos, NM

Trick-or-Treat on MainStreet

Trick–or–Treat on MainStreet will haunt downtown Los Alamos again on Friday, October 27th in 2017. Main Street and Central Avenue, from 15th to 20th Streets, close to auto traffic and become a safe pedestrian area where local businesses and organizations distribute candy to costumed families. While businesses in the downtown area open their doors to the public, this is also an opportunity for businesses and organizations that are not located in the downtown area to be involved. In 2016 an estimated 5,000 people took part in the weekend’s festivities.


Pumpkin Glow

The Pumpkin Glow is organized by the Los Alamos Arts Council and will next glow on Saturday, October 28th in 2017. The community brings their carved and decorated pumpkins for everyone to see on the Fuller Lodge lawn. Families then warm up to the music of a live band inside the Lodge. Don’t miss this family-friendly Los Alamos tradition.
