    We have been going to this family haunt since it started. It’s amazing watching the kids grow up and become these really scary ,professional actors and actresses. Hands down the best family friendly haunt in the Phoenix area. The only free haunt that will scare you. Making a donation is optional, but it’s the kind of haunt that makes you feel like donating. Thank you and can not wait to see what scary creatures awaits my family this year. Thx you Mount Mayhem staff
