Monterey Park Monster Mash

The City of Monterey Park's 8th annual Monster Mash is Thursday, October 15, 2026, from 4 to 7 p.m. at Barnes Park Field, 350 South McPherrin Avenue. Admission is free.

Carnival games, giveaways, and activities run through the evening, with entertainment around 6 to 6:45 p.m. The weekly farmers market and food trucks share the park that night. Bring a decorated treat bag or bucket.

The three-hour weekday window works for after-school costumes. Arrive closer to 4 p.m. if game lines matter more than the stage set.
