A walk way seen is seen in the Karnevil’s Revenge attraction at World of Khaos. The haunted house has two attractions and will remain open until Oct. 31.

Halloween is approaching, and for many, that means it’s time to scare — or be scared.

Two Tyler haunted houses are now open, kicking off the spooky season.

Owners of the World of Khaos, 816 E Oakwood St. in Tyler, and Corpse Grove Haunted Trail, 15972 Texas 64 E. in Tyler, have been preparing to welcome visitors.

Charles Cox, owner of World of Khaos, said it has been a long 12 months of preparation, but it soon will be worth it. While Cox does not change the attractions each year, new gags and scares are added to keep visitors on their toes.

Nightmares on Oakwood Street is the bigger and scarier “haunt” of World of Khaos’ two attractions, said set designer Joey Titman.

The second, Karnevil’s Revenge, is a bit less frightening, and visitors will walk through with 3D glasses to get the full effect.

“(World of Khaos) may be only two attractions — and there are a couple other haunted attractions in East Texas that are bigger or spend more money — but our care to attention and the level of scare is more intense,” Titman said. “We only have two attractions, but we really seem to boil down what we have into a better product. It’s not quantity over quality; it’s quality over quantity.”

The Corpse Grove Haunted Trail will be a little different than last year. Owner George Jones said two of the old rooms included in the attraction have been redone, and two rooms were added.

The two outdoor trail attractions at Corpse Grove are House of the Broken and The Wicked Playground.

House of the Broken is the shorter trail and is “kind of like a puzzle” visitors have to solve while being chased by monsters, Jones said.

The Wicked Playground is based on a school teacher accused of being a witch and killed by townspeople, only to come back and haunt the town of Corpse Grove. This is the longer haunt, at more than half-a-mile long.

“Most of the haunted houses in the area are all indoors, and so you’re kind of enclosed,” Jones said. “There’s something special and creepy in its own right being outside in the woods in the dark.”

Jones said he also added a third “haunt” this year in Mineola, 119 N. Johnson St., called The Annex. Unlike the other two, this haunt is all indoors. Visitors go through two buildings for this attraction, one of which is an old funeral home.

Jones said he enjoys being able to open a haunted attraction each year because it gives people something safe and fun to do. When he first moved to East Texas, he said he noticed a lack of activities for the “young folks,” and a haunted house was just one thing he could bring to the area.

“I think people like the adrenaline — they like the fear factor,” he said, “But they also like knowing they’re not really gonna get hurt.”

Both haunted house owners said they see thousands of people come to their attractions.

“Everybody likes to be scared. It just depends on what you’re scared of that determines how frightened you’re going to be,” Titman said. “It’s also an entertainment thing. It’s something you can do with your friends and family.”

World of Khaos is open 7 p.m. to midnight Friday and Saturday. Beginning Oct. 9, it will be open 7 to 10:30 p.m. Sundays for blackout nights. The last night of World of Khaos is Oct. 31 when it will have extended hours.
