NAPA COUNTY, California — Friday, October 30, 2026. Napa County has a useful split between daytime trick-or-treating in downtown Napa and a free evening block party in Yountville. Both fall on Saturday, October 31, and give families the opportunity to choose an outing without depending on ticketed wine-country attractions.

Where to celebrate on Saturday, October 31

Hometown Halloween in Downtown Napa

When: Saturday, Oct. 31, 11 a.m.–1 p.m.. Where: Downtown Napa around First Street and participating businesses.

More than 100 businesses are expected to mark participation with black-and-orange balloons; Boys & Girls Clubs seasonal activities continue around First Street into the afternoon. Check the original organizer listing.

Yountville Halloween Block Party

When: Saturday, Oct. 31, 5–9 p.m.; children’s area 5–7:30 p.m.. Where: North end of Washington Street, around 6764 Washington St., Yountville.

Free street party with music, dancing, food vendors and a 7 p.m. costume contest for individuals, groups and pets. Check the original organizer listing.

Napa’s independent indoor or paid options

When: Saturday, Oct. 31; reservation and admission vary. Where: Napa and nearby valley communities.

Local listings include ticketed craft and Halloween experiences; do not assume those are free or accept walk-ins. Check the original organizer listing.

A practical Saturday itinerary

The downtown Napa treat walk ends at 1 p.m., while Yountville starts later, so visiting both is feasible with a break in between. Bring a water bottle and keep the afternoon flexible. At the Yountville party, children’s activities end earlier than the whole event, and the official 7 p.m. contest schedule matters for anyone planning to enter.

Another local consideration

If you’re visiting from St. Helena, Calistoga or American Canyon, check the nearest community calendar before driving into Napa; different organizers may schedule events earlier in the day or require a reservation. Verify details here.

Before you leave

Schedules may change because of weather, staffing, capacity or other restrictions. Check the linked organizer’s current announcement, admission policies and any street closures before traveling. Children should carry emergency contact details; families should remain together in crowds and use marked crossings. A listed Día de Muertos observance is a remembrance tradition with its own cultural meaning, not simply another Halloween costume party.
