Per a post on the Linn’s Haunted House Facebook page, Des Moines’ older haunted house will be opening this year. They open tonight (Friday, October 18th, 2024). Here is the schedule they posted:

A fire last month caused a delay in opening, so there are only twelve nights you can crawl through this supermarket basement.
Folks, with all the issues that have been going on the past few years, and the fire this year, we are lucky to get another year to visit Linn’s. Even well-established haunts can close at any time. This year we lost Ames Haunted Forest and Tormented Souls Haunt and many still miss Ankeny Haunted Barn.
I hate to be a broken record, but, if you have fond memories of Linn’s, get out and visit them this year. This could be the very last chance you get. But let’s hope they are able to return in 2025.
