All Saints Lunatic Asylum is a professional haunted attraction in Apple Valley, California, presented as a tour through a long‑abandoned psychiatric institution. Its fictional backstory imagines a once‑advanced facility that lost its funding nearly 50 years ago, leaving its patients, doctors, laboratories, mortuary, chapel and other disturbing remnants behind. Visitors enter this continuing narrative as the building’s current owner supposedly attempts to restore its deteriorating wings.
The indoor walkthrough uses dark corridors, confined spaces, live performers, fog, strobe lighting, moving effects and sudden encounters to create an intense, disorienting experience. The attraction generally operates Friday through Sunday during October and also presents occasional themed events, including Turkey’s Revenge and Christmas at the Asylum: Elves Revolt. The experience is not recommended for young children, pregnant guests or visitors with conditions that could be affected by darkness, loud scares or sensory effects.
