This year the Invermere Haunted House will take place inside a house that’s spooky to start with. The house – which organizer Richard Matthews said is “a fairly creepy place” – is on loan from a developer and will be torn down shortly after the last monster escapes into the night.

There are two options for those looking for a Halloween fright on Friday, October 26th and Saturday, October 27th.

Friday night is geared toward families and those with a lower tolerance for guts and gore.

“It’s still scary but not to the max,” Mr. Matthews said.

But the screams will reach a crescendo on Saturday, which is for the bravest souls who may not survive the horrors of the night.

“We do a whole scare,” he said. There will be blood and graphic sights, and the bad guys will “kick it up a notch.”

This year’s theme is classic horror movies.

“All the classic Halloween monsters are going to be there,” Mr. Matthews said.

Blood-thirsty villains Freddy Krueger and Jason Voorhees will be hiding in the shadows and might lunge at you. Maybe even with a chain saw.

Spoiler alert: they aren’t allowed to kill you. In fact, none of the characters are allowed to touch the guests. But if you have a heart attack, that’s on you.

Each tour is guided and guests will have a safety word they can use if they get too freaked out.

“We really try our damndest to scare people,” Mr. Matthews said. “There’s always some people that have to use the safe word.”

Setting up a haunted house is a tricky balance because there’s a thin line between going so dark that it “will terrify people and have them not sleep for days” and not being scary enough to set a single one of their neck hairs on end.

In the past, up to 750 guests have tried to stifle their screams as they were startled by swamp monsters or marauding clowns.

“It’s a lot of fun. People really enjoy it,” he said.

The haunted house will be at 606 10th Avenue. Registration will be in the front yard, with $5 admission for children and $10 admission for adults. The Friday tours will run from 7 to 9 p.m., while the extra-scary Saturday event goes from 8 to 10 p.m.

After the Saturday scare, survivors can head over to a costume party at Ullr Bar to share their horror stories.
