Why the Final Monster Day is Top-Tier Colorado
1. Hollywood-Level Monsters in the Streets
This isn't your average neighborhood block party. Distortions Unlimited (the absolute legends behind the Travel Channel show Making Monsters) brings out their massive, hyper-realistic, and terrifyingly awesome creations. You will literally be walking shoulder-to-shoulder with towering ghouls, zombies, and wild creatures for the most insane photo ops of the summer.
2. The Friday Night Kickoff Concert
They aren’t just doing a Saturday street fair for the final year—they are kicking the whole weekend off with a massive party on Friday night. Head to the 9th Street Plaza from 6:00 PM to 10:00 PM for a rockin' live concert. Grab a drink, listen to some face-melting music, and watch as the first wave of monsters starts creeping into the crowd.
3. The Ultimate Costume Contest & Makeup Demos
Monster Day is the one day a year you get to go all out in August. The crowd energy is unmatched, and the costume contest is legendary. Not great at doing your own makeup? No problem. They have professional special effects makeup artists doing live demonstrations right on the plaza, plus over 80 themed vendors to shop from while you take in the sights.
The Rockstar King Verdict
Monster Day Greeley is top-tier Colorado culture—weird, wild, and incredibly fun. The fact that this is the 10th and final year makes it a mandatory weekend mission. It’s an unapologetic celebration of creativity that also raises money for the "Don't Be A Monster" anti-bullying campaign. Epic vibes for a great cause? That’s exactly how we like to party. Grab your crew and go witness the final Monster Day before it’s gone forever.
