MARIPOSA COUNTY, California — October 30, 2026. Mariposa County has a dated local Halloween gathering organized by Mariposa Safe Families, with an exact time and downtown entrance. The event is more relevant to local residents than a distant theme park, and the county’s mountain geography deserves a simple travel plan.
Saturday, October 31: events and important date distinctions
Mariposa Safe Families 13th Annual Trunk or Treat
When: Saturday, Oct. 31, 4:30–7:30 p.m.. Where: Mariposa Safe Families block, entrance near Eighth and Jones streets, Mariposa.
The host’s 2026 announcement invites families to decorated trunks, treats and a best-trunk vote. The organization’s office is at 5070 Bullion Street; use the event entrance rather than the office address for arrival. Original listing or organizer.
How to organize a realistic day
Arrive during the 4:30–7:30 p.m. window and keep children on the designated pedestrian route between parked trunks. Drivers from Coulterville or Wawona should account for dark two-lane mountain roads. The famous Hornitos Day of the Dead ceremony is traditionally November 2; do not label a Monday remembrance as Saturday Halloween.
What else to know for the weekend
For a Sunday daylight alternative, use official National Park Service hours and road conditions for any Yosemite-area plans; a normal park visit is not a special Halloween performance.
Public-safety and accuracy reminders
Halloween falls on Saturday, October 31, 2026. Date-specific source calendars are linked above. Programs may move because of rain, public safety, organizer decisions, limited capacity or staffing. Check actual venue and ticket pages again immediately before leaving, and do not assume the hours of an earlier year’s event. Some cultural remembrance programs occur on Sunday, November 1 and should be described distinctly from Halloween. Use sidewalks, crosswalks and supervised treat routes.
