Beyond Spooky

You could put on some scary face paint and celebrate Halloween with some mild, even family-friendly spookiness at a theme park, or throw on one of this year's most popular Halloween costumes to take part in frightfully fun Halloween parades and festivities happening across the country. But maybe that's not scary enough for you. Here are some haunted houses and immersive experiences that are so terrifying and physically demanding that participants have to sign waivers before entering. Don't say you haven't been warned.

Castle of Chaos allows participants to choose from five levels of fear. At the lowest level, monsters are repelled by your glow stick. But at the highest, they may pick you up, drag you through doorways, or restrain you. For those who crave the most hardcore of haunts, they offer Krusebel, an extreme, hours-long experience that combines both physical and psychological torments.

The 17th Door Haunt Experience/Yelp

17th Door

Fullerton, California
17th Door follows the ongoing story of Paula, a college student-turned-murderer now imprisoned in a treacherous penitentiary. As her fellow inmates, guests will wind through the maze in an attempt to unlock the story and escape unscathed. Previous shows have involved real cockroaches, being smothered in a ball pit, lots of touching by handsy actors, and virtual reality add-ons. Guests who can no longer endure the experience can yell "Mercy" to escape. Feel like you can go longer? A new add-on called "The Field Trip" is available, in which guests are taken to a remote, off-site location for even more intense scares.

This haunt is made by a group of dedicated artists and counts horror enthusiasts Elijah Wood and Guillermo del Toro among its fans. Scarehouse also offers Stop the Invasion, a horror-themed escape room.

The Fear Experiment is an immersive, psychological horror experience. The experience is for adults only, who will sign a waiver and receive a safe word. Though the experiment warns of physical contact, discomfort, aggression, and nudity, they also promise to "allow you to push your limits, test yourself, and find out what you're really made of." What that means is unclear, as all participants are instructed to never share spoilers online or in-person.

More immersive experience than haunted house, Hvrting bills itself as personalized immersive horror. The Los Angeles-based show customizes its plot and various details to its small audience or single experience-goer, tapping into their innermost fears. Attendees can expect terrifying (though often humor-driven) plot lines, plenty of sexual innuendo, and the chance to survive your own personal horror movie.

Overnight paranormal tours are also offered.
