Erebus Haunted Attraction

Erebus Haunted Attraction occupies a four-storey former parking garage at 18 South Perry Street in downtown Pontiac, Michigan — half a mile of walk-through horror threaded vertically through a building abandoned for decades before brothers Edward and Jim Terebus, veterans of Detroit-area haunts, opened Erebus in 2000; named for the Greek darkness between earth and Hades, it held the Guinness World Record as the largest walk-through haunted attraction from 2005 to 2009 and remains among the biggest anywhere, famous for effects that physically involve the visitor — floors that give, walls that press, things that grab from below — around a time-machine storyline refreshed each season, with a hundred-odd actors nightly through the Halloween run and year-round escape rooms alongside. It is a commercial scare attraction, anchoring the platform's Halloween Attractions category rather than claiming a documented haunting — though a fifty-year-derelict garage in an old downtown gives its crew the customary between-shift stories, told with relish. Tickets, dates, intensity warnings and age guidance from the official site; not recommended under thirteen.
