Oogie Boogie Bash – A Disney Halloween Party is a separately ticketed Halloween event at Disney California Adventure Park at the Disneyland Resort in Anaheim, California. It takes place on select nights in August, September, and October and runs from 6:00 p.m. to 11:00 p.m., with ticket holders able to enter the park earlier in the evening. The event is organized by Disneyland Resort and is distinct from regular daytime park admission. The party is a family-oriented after-hours event built around Halloween-themed entertainment, including character encounters, treat trails, and the Frightfully Fun Parade. Disneyland Resort describes it as a recurring seasonal event, with dates announced annually for the fall season.
