The teenagers will be screaming. The men will be screaming. Everyone will be screaming. Haunting rooms. Spooky characters and then there are the ones that are alive! Come out and startle you right at the perfect time. Professional haunting vibe. Must see!

We have been going to this family haunt for the past 7 years now, and beware, this is the most terrifying haunted house in Arizona. I have seen teenage girls leaving in tears. The jump scares get us every time and it is a different setup every year. I have been taking my daughter since she was little so she is a seasoned veteran, and we love every horrific moment! They have a wimpy version if you are too scared to do the regular. Extreme on fear, low to moderate gross out.

Do not sleep on this backyard haunt. This family does it right. Scares come from everywhere and their sets are very cool. This is one of the best haunts I have been too in the last 5 years.
The man in the wheel chair almost made me cry. My kids and I could not stop talking and laughing about it.
I highly recommend it for the true Halloween fans.

The family that does this haunted house out of their back yard does a fantastic job. It is the BEST haunted house that we have been too. It is absolutely terrifying with so many jump scares that you won't see coming. The actors do a great job drawing your attention to something that looks creepy then jumping out from somewhere else to give you a good scare. This is a MUST DO haunted house for our family.

Went tonight to go check this place out, it was amazing! It took a few minutes to get through. You didn't really see the scares coming, they did a great job! ??

Went to opening night last night. It was great and their circus theme was scary fun. It was very well done. My 10 year old wants to go back.

This is a very scary haunt. Totally caught us all by surprise. I advise you to stay away if you get scared easily.

Much better than the high price haunts. I love to see this family's passion for Halloween. It was scary but super fun. My 6 and 8 year old loved it and got hooked last weekend. We will going this weekend again.

Nice family run setup. Perfect length for little kids (or chicken type grown ups), not too long, not too short. excellent execution. They don't charge admission, but a donation is fair for their effort.
