Denver’s Halloween runs on two tracks: the big ticketed nights at the zoo, the botanic gardens and the Molly Brown House, and the free or nearly free neighborhood events at churches, parks and the Children’s Museum. This page lists every Halloween event in Denver that we have verified against its organizer, in date order, with the time and the cost on each line. Every item links to our full listing, which has the address and the official source. We add new events here as we verify them.

This week and weekend

Halloween week

Before you go

Glow at the Gardens and Boo at the Zoo both sell timed tickets and both sell out popular nights, so buy before you drive. The church trunk-or-treats above do not print a cost, so check the linked page or call ahead. For the rest of the metro, see Halloween events in Littleton and Highlands Ranch and Halloween events in Wheat Ridge, Arvada and Lakewood, and our weekend guide for Oct. 23 to 25 for everything else.

Jessica Holland

FOUNDER + EDITOR, COLORADO LOCAL

Jessica Holland is a Colorado mom, entrepreneur, marketer and founder of Colorado Local. After years of constantly searching for things to do with her family, local businesses worth supporting, educational experiences for her girls, worship nights, community events and simply more GOOD news, she realized the resource she wanted didn’t really exist in one place. So she built it.

Jessica is also the founder of Holland Health Marketing, where she helps businesses grow through digital marketing, local visibility and community connection.

Her Christian faith is a big part of who she is and the way she sees the world. Colorado Local isn’t a faith-only publication, but you’ll absolutely find faith here, alongside stories about neighbors helping neighbors, churches serving their communities and people using what they have to make Colorado a little brighter.

She lives in Northern Colorado with her husband, two daughters and their very large Newfoundland, Mugsy.

Her mission for Colorado Local is pretty simple: help people get out, connect, support local and find more of the good happening right in front of us.
