Fort Collins spreads its Halloween across two weeks: lantern-lit pumpkins and a farm trick-or-treat street this week, then a downtown toddler parade, a horror-movie symphony night and the Gardens’ Day of the Dead altars in the days around Oct. 31. This page lists every Halloween event in Fort Collins 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

Pumpkins on Parade and Treatsylvania are both outdoors after dark, so dress for the forecast; Treatsylvania tickets went on sale Oct. 7 and the Sunday afternoon slot is the one for the youngest kids. Osborn Farm in Loveland is the closest pumpkin patch with no admission fee. For the towns to the south, see Halloween events in Loveland and Johnstown, and our weekend guide for Oct. 23 to 25 has the rest of the Northern Colorado calendar.

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.
