Additionally, remember to review the websites for any age restrictions, as some of these attractions may be a bit too spine-tingling for the little ones.

Winchester Mystery House

This Halloween, venture into the eerie Winchester Mystery House, where legend says restless spirits influenced its construction. Sarah Winchester, the reclusive widow of a firearm tycoon, believed that the spirits of those killed by Winchester rifles haunted her. To appease these spirits, she continuously built onto the mansion for nearly forty years, resulting in architectural oddities like staircases that go nowhere, doors that open into walls, and a confusing maze of rooms and hallways. It's thought that the peculiar design was intended to bewilder the spirits that she felt were pursuing her. Are you brave enough to explore the secrets of this enigmatic mansion during the spookiest season of the year?

This year, the Winchester Mystery House is introducing a brand-new Halloween experience: Festival Fright Nights, produced in partnership with Thirteenth Floor Entertainment Group—the creators of immersive haunted attractions across the country.

Running on select nights from September 26 through November 1, this immersive event transforms the estate into a 1920s masquerade gone wrong. Guests will encounter eerie theatrical sets, live performances, and multiple haunted attractions spread across the property—each revealing more of the mansion’s ghostly lore.

To see the full lineup of experiences, VIP add-ons, and ticket information, visit Festival Fright Nights. Tickets are expected to sell quickly, so plan ahead!

Daytime mansion tours and year-round activities—like the Sarah Winchester Garden Tour, Axe Throwing at the Stables, and Sarah’s Attic Shooting Gallery—are also available for those who prefer their thrills with a little more daylight.
