Our top 8 family Halloween and autumn picks
1. The Great Big BOO at Gilroy Gardens
Location: Gilroy. Dates: Fridays–Sundays through November 1; closed October 10.
For a full-scale but gentle Halloween party, Gilroy Gardens stages live character shows, a family costume atmosphere and a trick-or-treat trail. The combination of rides and performances makes it a strong single-destination outing. Ordinary admission or eligible membership is needed; check the operating calendar rather than assuming every weekend day is open.

2. Happy Hollow Fall Family Sleepover
Location: San José. Dates: October 17–18, 2026.
One of the county’s most unusual options is staying overnight at Happy Hollow Park & Zoo. Families can enjoy animal encounters, games, crafts and flashlight-led experiences. This is a paid educational program for older children accompanied by adults, not standard daytime park entry.

3. Trick-or-Treat the Row
Location: Santana Row, San José. Dates: Tuesday, October 27, 2026, 10 a.m.–noon.
A lively, free daytime shopping-district event especially suited to children who prefer simple trick-or-treating and street performers. Organizers list pumpkin decorating, music and characters on stilts. Bring a candy bag, check participating storefronts and come early to beat crowds.

4. Pumpkins in the Park
Location: Discovery Meadow, San José. Dates: Saturday, October 10, 2026.
This downtown seasonal festival offers an early-month opportunity to enjoy pumpkins and community activities rather than waiting until Halloween night. Visit San José’s official fall-events roundup confirms the 2026 date; verify hours and activity rules with the individual event organizer.

5. Symphonic Spooktacular
Location: California Theatre, San José. Dates: October 24–25, 2026.
For musically minded families, a Halloween-themed Symphony San José performance is a different kind of holiday tradition. Consider this for older elementary-age children who enjoy concert halls more than candy trails. Check the specific showtime, age guidance and ticket availability.

6. Farmer Mike Pumpkin Carving
Location: Santana Row, San José. Dates: October 24–25, 2026.
A pumpkin-carving demonstration adds local creativity to a Santana Row visit. This is a seasonal experience rather than a full theme-park festival; it works well as one stop in an easy day of dining and shopping. Confirm demonstration hours before going.

7. Trick or Treat Along Lincoln Avenue
Location: Willow Glen, San José. Dates: Friday, October 30, 2026.
Willow Glen’s retail corridor gives the neighborhood Halloween experience a walkable setting. Choose this if your family wants a costume outing without a lengthy drive to a big attraction. Check business participation and event windows with the local association.

8. Community Day: Día de los Muertos
Location: San José Museum of Art. Dates: Saturday, October 24, 2026.
An art-centered cultural option in the broader autumn holiday season. Día de los Muertos is not the same holiday as Halloween; include it for families interested in learning about the distinct tradition through programming at the museum. Verify activity details and museum admission policy.

Make a realistic family itinerary
The Great Big BOO is closed on October 10 for a private event, even though it otherwise operates selected Fridays through Sundays. Ticketed zoo sleepovers have restrictions; check ages and chaperone rules first.
Check costumes, accessibility, age limits, refunds, parking and weather-related closures before booking. Some options are community events while others are paid attractions; ticket availability can change quickly.
