Halloween in San Francisco doesn't have to mean expensive tickets or a late-night party. This year's calendar includes park celebrations, neighborhood trick-or-treating and family festivals across the city.

Here are several events to consider for October 29–31. Schedules and activities can change, so check the organizer's page before heading out — especially if you're bringing young children.

Friday, October 30: Scaregrove at Stern Grove

San Francisco Recreation and Parks lists its free Scaregrove celebration for 3–9 p.m. at Sigmund Stern Grove, 19th Avenue and Sloat Boulevard. The program includes a haunted house, maze, carnival rides, crafts and live entertainment. Food will be sold separately. Some spooky attractions may be too intense for younger kids. Official event details.

Saturday, October 31: Halloween Hoopla

The Children's Garden at Yerba Buena Gardens hosts Halloween Hoopla from noon to 3 p.m., with performances, activities and a costume parade. The event is geared toward children under 10 and is free, with RSVP available. Official event details and RSVP.

Thursday, October 29: Ferry Building trick-or-treating

Make the most of the weekend

Dress for cool evenings, allow extra time for transit, and check whether costumes or contest entries need advance registration. Families can also look to neighborhood libraries and merchant corridors for smaller celebrations closer to home.
