The thrills and chills of the scariest season are returning to Six Flags Great Adventure this fall.

Fright Fest launches appropriately enough on Friday, Sept. 13, at the Jackson thrill park, running weekends and select weekdays through Nov. 3.

The 30-hour Six Flags Coffin Challenge returns for its second season on Oct. 13 and 14. Six guests will be chosen from thousands of applicants to survive, as the challenge's name implies, 30 hours in a coffin.

Butch Patrick of "The Munsters" fame is the guest emcee, and interested participants can register via www.sixflags.com/greatadventure starting Monday, Sept. 9.

The resurrected Coffin Challenge is just one of more than 20-Halloween themed happenings going on during Fright Fest. There will also be mazes, ghoul-filled "scare zones," live shows and nighttime runs through some of the most shocking roller coasters in the country.

Additional haunted maze passes are required for terrifying attractions such as "Aftermath," "Blood Shed" and "Cell Block 6."

There are plenty of all-ages entertainments included with park admission, including the 20th anniversary of the "Dead Man's Party" stage show, the acrobatic spectacle "Unleashed" and the kid-friendly Trick-or-Treat Trail.

The scares return to Six Flags Great Adventure next year — the park made headlines last week with the unveiling of the record-breaking, single-rail Jersey Devil Coaster, set to take flight in summer 2020.
