Winchester Mystery House, invites guests back to Festival Fright Nights at Winchester Mystery House, for a reimagined Halloween festival experience unfolding throughout the historic San Jose estate. Running select nights from September 18 through November 1, the 2026 season.

New this season, The House of Spirits follows Sarah Winchester’s loyal butler following her death as he desperately attempts to care for the sprawling estate as strange activity spreads through the halls.. Armed with ghost traps and unwavering determination, he struggles to contain the spirits as whispers, shadows and unsettling encounters suggest the house is slipping far beyond his control.

The estate’s story grows darker in The Final Descent: No Escape, where the staff who once cared for the mansion have been consumed by the darkness beneath the grounds. What remains now stalks the halls as guests fight to escape a house fully surrendered to evil. In The Root of All Evil, something ancient stirs beneath the estate. Inside the greenhouse, twisted roots, corrupted growth and strange creatures reveal an evil lurking in the soil that has been feeding on the property since long before Sarah Winchester arrived.

Guests can extend their visit with a collection of interactive add-ons and seasonal experiences. Like the new Hide & Seek: The Lost Children experience, which leads guests into the mansion’s attic, a space rarely open to visitors, where laughter echoes and unseen children dart through the shadows, always just out of reach. The game continues deeper into the attic, where the children have been waiting a very long time for new playmates. Additionally, guests can enjoy a variety of seasonal treats, while those 21 and over can sip on specialty cocktails before or after braving the horrors of the Winchester estate.
