Longmont's Día de los Muertos Season Runs Three Weeks. Most People Only See One Afternoon of It.

September 17, 2026

If you've lived in Longmont through an October, you've probably stood at 4th Avenue and Kimbark Street on a Saturday afternoon and watched a procession of dozens of giant papier-mâché puppets wind through downtown, led by Aztec dancers, while kids get their faces painted as sugar skulls and food trucks line the block. That afternoon is real, and it's worth your time. But it's also the loudest part of something much longer, and if that's the only piece you've caught, you've missed most of what Longmont actually built.

This year marks the 26th anniversary of Longmont's Día de los Muertos celebration, the longest-running public Day of the Dead observance in Colorado, running continuously since 2001 and drawing more than 6,000 people annually. The Family Celebration, the one everyone photographs, lands on Saturday, October 24, from 11 a.m. to 3 p.m. at 4th and Kimbark. That part of the calendar gets covered every year. What doesn't get covered as often is that the season around it stretches for weeks, handed off between four different organizations, each running its own piece with its own venue, its own price point, and its own audience.

Four Organizations, One Season

Longmont's Día de los Muertos isn't produced by a single group. It's a collaboration between the Longmont Museum, the Firehouse Art Center, the Longmont Downtown Development Authority, and El Comité de Longmont. Each one owns a distinct piece of programming, and none of them run on the same schedule as the Saturday festival. Elaine Waterman, the Firehouse Art Center's executive director, has described the season as bringing "cross generational, cross cultural storytelling and tradition sharing" across its different venues and audiences. That's not a marketing line. It's a fair description of how differently each event actually feels.

The season opens quietly, not loudly. This year, the Firehouse Art Center's Catrina exhibit opens October 10, two weeks before the street festival, and stays on view through early November. It's free, it's usually uncrowded, and it's where the community-made Catrinas actually live before anyone sees them at the bigger events downtown. In past years, the exhibit has paired local and emerging artists' work with pieces like artist Ricardo Soltero's calaca sculptures, plus artwork from children enrolled in the Firehouse's bilingual Art Attack program at Casa de la Esperanza. If you want to see the season at its most personal, this is the entry point, not the parade.

What Happens Between the Exhibit and the Festival

Downtown business altars are the part of the season most residents drive past without noticing. In recent years, storefronts along Main and Coffman have built their own ofrendas, personal altars honoring specific people, and kept them up for public, self-guided viewing for weeks after the opening. Maps to the altar locations have been available at the Longmont Downtown Development Authority's office on Main Street. It costs nothing, it takes twenty minutes on foot, and it's the version of the holiday that has the least to do with crowds and the most to do with the actual point of the tradition, which is remembering specific people by name.

Then comes the Saturday everyone knows. The Family Celebration at 4th and Kimbark is free, all ages, and built around live music, dance performances, sugar-skull decorating, and food trucks. It closes with the Gigantes Procession, dozens of giant puppets built by local artists, led out from the festival grounds through downtown alleyways and back to the stage at 4th and Kimbark. Parking is available on-street or in downtown lots, and in past years a free shuttle has run between downtown and the Longmont Museum so attendees could catch both the street festival and the museum's exhibit in the same afternoon.

Here's a rough map of how the season has typically unfolded, in the order most residents encounter it:

  • Firehouse Art Center exhibit opening — quiet, free, community-made Catrinas on view for weeks
  • Self-guided altar tours — free, downtown storefronts, maps from the LDDA office
  • Family Celebration — the big Saturday, free, 4th and Kimbark
  • Gigantes Procession — same day, follows the festival, ends back at the main stage
  • Catrina Ball — ticketed evening event, historically at the Dickens Opera House on Main Street, though in at least one recent year it moved to the alley behind Maker General between Third and Fourth
  • Noche de Museo — the closing night, a ticketed performance in the Longmont Museum's Stewart Auditorium

The Part That Keeps Moving

What's interesting about the Catrina Ball and Noche de Museo is that they haven't stayed put. The Catrina Ball has run at the Dickens Opera House in some years and in an outdoor alleyway setting behind Maker General in others, with admission for the Dickens Opera House years priced at $15 in advance and $20 at the door. Noche de Museo, the season's closer, has featured a lineup spanning ancient Aztec dance with Grupo Mexica Tlahuitzcalli to the genre-bending sound of iZCALLi, with a recent season's tickets priced at $18 general admission, $15 for students and seniors, and $12 for museum members. None of that is fixed the way the Saturday festival is fixed. It shifts based on venue availability and who's performing that year, which is part of why it doesn't get the same advance coverage as the parade everyone already knows to expect.

That's the actual shape of the thing. The festival draws the crowd because it's the easiest to plan around: one Saturday, one location, free admission. But the season built around it, the gallery opening, the altar walk, the ticketed evening events, is where the tradition does most of its work, and it's largely invisible unless you're already looking for it.

Catching More Than the Saturday

If you've only ever caught the Family Celebration, this year is a reasonable one to see the rest. The Firehouse Art Center's exhibit opens October 10, giving you two full weeks before the street festival to see the Catrinas before the crowds do. The self-guided altar tour costs nothing but a walk down Main Street. And if you want the version of the season that closes it out, keep an eye on the Longmont Museum's calendar for the Noche de Museo date, since it tends to land in early November and sells tickets ahead of time.

None of this requires planning your whole October around it. It requires knowing that the puppet parade isn't the whole story, just the part that's easiest to photograph.

If you're new to Longmont, or thinking ahead to what makes a neighborhood feel like home rather than just an address, this is the kind of texture that doesn't show up on a listing sheet.
