Our top picks for families:

Sept. 13-Oct. 31: Unhinged at Winchester Mystery House, San Jose

Autumn is prime time for this 160-room mansion in San Jose, which has a bizarre origin story: It was built by an eccentric heiress who was trying to ward off ghosts. This year’s event, “Unhinged Hotel,” unravels within this frame story: a group of friends, stranded due to car trouble, stumble upon an old hotel with plenty of vacancy. (Spoiler alert: It doesn’t lead to a night of undisturbed sleep.) After the experience, peruse the house’s new Halloween Museum and catch your breath outside with snacks and drinks at Café 13.

Sept. 29-Oct. 31: Heartstoppers Haunted House, Rancho Cordova

Scream your way through four scare zones--with themes like the dark hospital on the hill (“The Ward”) and a raising of the dead (“Redemption!”)--on select nights in this decked-out, three-story building in Rancho Cordova. To release the tension afterward, enjoy the outdoor offerings of carnival games, live performances, and character photo ops.

Oct. 4-27: HalGLOWeen at the San Diego Zoo, San Diego

Contest winners will receive tickets to Glowfari, the zoo’s holiday nighttime event that runs Nov. 10–Jan. 28.
