Halloween’s NightMARE Island

We are excited to share next month’s Halloween’s NightMARE Island happening right here in Building 116. 

Halloween’s NightMARE Island is a beloved, all ages, annual Halloween-themed festival presented Friday through Sunday, all of the weekends in October.  To purchase tickets, please visit: 


New for 2021: 

• They will be in our 45,000 square foot warehouse, with 3 story ceilings and roll up doors, giving it an "open air' feeling! But you won't believe how they have transformed it! In this new location they were able to add an additional 900+sqft of haunt, so get ready for a true rollercoaster of frights!
• Kids activity area will be open.

They’ll be open at 5pm, every Friday-Sunday in October - that's 5 weekends and 15 days total!
*From 5-6pm there are NO scare actors in the haunted house, NO live animatronics, and NO actors roaming the property outdoors. This is for younger guests and those who do not like having things jump out at them.

*From 6pm on there ARE scare actors & live animatronics in the haunted house, as well as actors roaming the property outdoors. At this time they will be in FULL EFFECT!
