Combine Fall Fest and Barktoberfest and what do you get? Frightfully fun activities that include game and activity stations, photo opportunity areas, airbrush tattoos, balloon animals, a dog costume parade and contest, and trick-or-treating with pet service and product vendors are part of this new Halloween Party. Families (pets included) are invited to wear their Halloween finery and head over to Pantera Park for the City's first Halloween Party that combines elements of Barktober Fest and Fall Fun Festival.

The dog costume contest has three categories and staggered parade and judging times, with Best Dog & Owner Costume Combo, Best Large Dog Costume (25 pounds and heavier), and Best Small Dog Costume (lighter than 25 pounds).

 Event admission is free and open to the public, and costumes are encouraged but not required.  

Other Diamond Bar events include a summer concerts series and Easter Egg hunts.
