Sinister Sidney – Frights on Filmore St. is a 40 – 60 minute (self-paced) horror filled trek through forest and farm. Open Friday and Saturday nights in October. Located on the old haunted Canon property (circa 1890) in Sidney Iowa, your adventure takes you through over 30 Frightful scenes on the over 1/2 mile trail, including the brand new Green Hollow Mushroom Trials, The Pit, The Catacombs and House of Gein. Also a bonfire and hot Coco stand. This includes a real active cemetery (Mulberry Grove) on site. With over 30 individual horrors, this trip is not for the faint of heart. For that reason, small children under 12) are frowned upon, and promptly eaten.

OPENING NIGHT RECAP

We survived! Thank you to the brave souls who walked through our doors, the energy was high, the makeup was creepy, and apparently 10% of you left with less bladder control.

Now we want to see YOUR night!
Did you hit our photo ops? Get pics with the monsters? Capture something we missed?

DROP YOUR PHOTOS IN THE COMMENTS & TAG YOUR FRIENDS!

We’ll be sharing some of our favorites too!

Opening night is over… but the season is just getting started.
