Great collection of scares, anamatronics and original features makes the experience unique. They also do away with the tired cliches (no chainsaws!) because they don't need them. Highlights include the spider web, an original and maddening "white room", and a lighting method that creates a strange illusion. Finally, the length is better than most and the pace is well done. Bravo. ?!

The beast of all home haunts! The hulk of home haunts. This small town haunt packs a punch that you'll feel throughout the entire spooky season!

Honestly one of the best haunts.I've been through losts of others and I would put this on my top list. Great makeup work and acting. Loved the variety of jumpscares, definitely listen to the 12 and up age rules. All together it was a great time lots of fun and I hope it continues for many years.

This is a premiere haunt in Iowa and the region! Always improving, always growing. Mike and Laurie clearly know what they are doing and successfully bring the community of Sidney, IA along with their success! A true destination in October!

Went to sinister Sidney again for the second time this year and every time it's just as good as the last. We will always make it a tradition to come every year. By far the best Haunted attraction!
