Halloween’s ancient origins date all the way back 2000 years to when the Celts believed the worlds of the dead and the living became enmeshed. To honor the ghosts of the dead returning to earth, they partied. Today, we have lots of Halloween partying options, but instead of building huge bonfires and sacrificing animals, check out these local Halloween haunts.

HALLOWEEN HOP ON MONTANA — The boundaries between shopping and trick-or-treating become blurred on Montana Avenue in Santa Monica.
