MERCED COUNTY, Calif. — October 30, 2026. Merced County’s Saturday Halloween schedule is strongest for families on its west side, with a city-organized festival in Los Banos and a city-sponsored downtown trunk-or-treat in Gustine. Local reporting gives a precise start, end and locations for both.

Saturday, October 31: what is actually scheduled

Los Banos Halloween Fest

When: Saturday, Oct. 31, 4–8:30 p.m.. Where: AG Sports Complex, 700 North Mercey Springs Road, Los Banos.

City-organized free community celebration advertised with maze, pumpkin painting, games, bounce houses, crafts, vendors and family activities. Source and last-minute checks.

Gustine Halloween Trunk-or-Treat

When: Saturday, Oct. 31, 6–8 p.m.. Where: Main Street, downtown Gustine.

The City of Gustine advertises a decorated-car treat gathering; confirm traffic rules and exact block access through city contacts. Source and last-minute checks.

Merced Harvest Carnival

When: Saturday, Oct. 31, 5–8 p.m.. Where: Christian Life Center, 650 East Olive Avenue, Merced.

Regional community reporting lists an evening harvest carnival with activity booths and candy, useful as a city of Merced alternative. Source and last-minute checks.

Plan your Halloween day

Los Banos and Gustine have partially overlapping times; choose based on travel distance and children’s needs. Families in central Merced may find the Olive Avenue carnival more practical. These locations span the county and should not be represented as one walkable holiday route.

Sunday, November 1, and other options

Los Banos Enterprise describes the events in its October 2026 community guide; contact the individual venue to confirm any last-minute change, particularly for an outdoor event.

Verify before traveling

The date of Halloween is Saturday, October 31, 2026. A program held on Friday, October 30, should not be mistaken for a Saturday event. Organizers may change hours, fees or locations. Confirm the latest calendar and any required booking; some tourism and community calendars aggregate submitted listings rather than manage the event themselves. Keep children’s costumes visible, use marked crossings and plan for autumn darkness. For live state-road conditions use Caltrans QuickMap.
