The most common question before attending a Dia de los Muertos celebration is whether you need a costume. The answer — no, you don't — reveals almost everything essential about the holiday.
Dia de los Muertos is a reunion. On November 1 and 2, the spirits of deceased relatives are believed to return for a brief visit. Families build ofrendas (altars) laden with photographs, the deceased's favorite food and drink, marigold petals to guide spirits home, copal incense, candles, and water. The goal is not to ward off the dead. It is to welcome them back, share a meal, and remember them with laughter and celebration alongside the living.
The holiday is approximately 3,000 years old, rooted in Aztec and broader Nahua traditions that viewed death as a natural part of a continuous cycle rather than a finality to fear. When Spanish colonizers arrived in the 16th century, those Indigenous practices fused with the Catholic calendar — specifically All Saints' Day (November 1) and All Souls' Day (November 2). The original summer observances shifted to late autumn near the fall maize harvest. The result is a syncretism: pre-Columbian cosmology reshaped by Catholic calendar influence, still recognizable on both sides.
Halloween is Celtic — derived from Samhain, the ancient Irish new year, when wandering spirits might cause harm. The costume tradition is protective, a strategy for deflection or disguise. The two holidays share a proximity on the calendar and a cultural shorthand of skulls; they share almost nothing else in origin or intent.
The centerpiece of any Dia de los Muertos celebration is the ofrenda — an altar built to receive returning spirits. At home, an ofrenda holds family photographs and the deceased's personal objects. At public celebrations, community ofrendas may honor famous figures, community members lost in recent years, or entire categories of the departed — workers who died in industrial accidents, migrants who died crossing the border, veterans.
The elements follow a specific logic. Cempasuchil (marigolds, called *flor de muerto* or flower of the dead) scatter petals from the ofrenda to the front door, creating an aromatic path that guides spirits home. The Aztecs used marigolds medicinally and associated them with the sun; their bright orange-yellow color is now the holiday's visual signature. Copal incense — made from tree resin and used in Mesoamerican ceremonies for millennia — purifies the space. Pan de muerto is a sweet egg-enriched bread shaped into a round loaf decorated with bone-shaped dough and flavored with orange and anise; it is placed on the ofrenda and eaten. Sugar skulls (calaveras) are personalized with the deceased's name and are a decorative craft tradition as much as a religious practice.
At public US celebrations you'll encounter altars built by families who wish to share their memory publicly, vendors selling marigolds and pan de muerto, art installations, community processions, and participants in traditional calavera makeup — white face paint, flowers in hair, black details around the eyes, modeled on the Catrina, a 1913 satirical lithograph by Jose Guadalupe Posada. The makeup is a costume in the theatrical sense. It is not a requirement, and understanding where it comes from makes wearing it more meaningful.

The oldest Dia de los Muertos celebration in the United States takes place at Olvera Street — the one-block historic marketplace on the site of Los Angeles' original 1781 pueblo, a pedestrian alley of craft stalls and taquerias in the shadow of the 1818 Avila Adobe, the city's oldest surviving structure.
The nine-night festival runs October 25 through November 2. Community altars are on display October 28 through November 2; a nightly procession starts at 7 p.m. with an indigenous blessing ceremony. Admission is free. Olvera Street is inside El Pueblo de Los Angeles Historic Monument, 125 Paseo de la Plaza, Downtown LA — a 10-minute walk from Union Station, which connects to the Metro Red and Purple lines.
Gloria Molina Grand Park (200 N. Grand Ave., Downtown, five minutes from Olvera Street) hosts free ofrenda installations created by 17 artists and community groups, running through November 2. The combination of Olvera Street and Grand Park makes Downtown LA the most accessible Dia de los Muertos experience in any US city — both free, both walkable from the same Metro stop.
Hollywood Forever Cemetery (6000 Santa Monica Blvd., Hollywood) runs a separate ticketed celebration known for theatrical performances and elaborate community altars. In 2026 that event occurred October 24 and is now concluded; 2026 tickets ran around $60 and it sold out weeks in advance. Worth planning for 2027 if you're interested — book the moment tickets go on sale.
Chicago's Mexican-American community is concentrated in the Pilsen and Little Village neighborhoods on the South Side. Pilsen is home to the National Museum of Mexican Art — the largest Latino arts institution in the United States and the anchor of Chicago's Dia de los Muertos calendar.
The museum (1852 W. 19th St., Pilsen — Pink Line, 18th Street Station) runs a dedicated exhibition every fall. The 2026 show, 'Where Memory Lives: 40 Years of Dia de Muertos,' runs September 25 through November 29. Admission is free. The museum is open Tuesday through Sunday, 10 a.m. to 5 p.m.
The exhibition features community altars built by Chicago families alongside the museum's permanent collection of Mexican and Mexican-American art. The 40-year retrospective makes this year's show particularly substantial — it covers the museum's own history of presenting the holiday alongside the community traditions it grew from.
Pilsen's 18th Street between Halsted and Western is lined with murals — one of the largest concentrations of Mexican muralism outside Mexico — along with taquerias, panaderias, and bakeries. Combine the museum with a walk along 18th Street and lunch at one of the neighborhood's taco counters for a half-day that covers the cultural context the holiday comes from.
San Antonio's Mexican-American identity runs deeper than any festival. The city was founded as a Spanish colonial settlement in 1718, spent over a century as part of Mexico, and became American in 1845. About 64 percent of the city's population identifies as Hispanic or Latino. Dia de los Muertos is not an imported celebration here — it is a continuation of a practice that predates the city's current national identity.
Muertos Fest at Hemisfair Park (434 S. Alamo St., Downtown) is one of the largest Day of the Dead events in the United States, drawing over 100,000 attendees across three days with 80+ community altars and five performance stages. In 2026 the festival ran October 23-25; those dates have passed. The late-October window is a reliable annual fixture — plan to arrive in the week before November 2 for the broadest range of events. La Villita (418 Villita St., Downtown) and Historic Market Square (514 W. Commerce St.) both host additional events through the holiday.
San Antonio's cemetery observances on November 2 — families gathering at San Fernando Cemetery with food, flowers, and candles — are the oldest layer of the tradition in the city. They are not marketed as events; they are simply practiced, year after year.
San Francisco's Dia de los Muertos procession in the Mission District has run continuously for over 44 years — one of the oldest in the United States. Organized by El Colectivo del Rescate Cultural and the Calle 24 Latino Cultural District, the procession assembles at 22nd and Bryant Streets and marches down 24th Street, the heart of the Mission's Latino commercial corridor, to Potrero del Sol Park where community altars are displayed.
In 2026, November 2 falls on a Monday; the procession is expected to take place November 1 or 2 (check calle24sf.org for the confirmed date and starting time). The procession is free and typically begins around 7 p.m. Arrive early to see the altars at Potrero del Sol before the march starts and walk 24th Street while the panaderias and taquerias are open.
The Mission is San Francisco's oldest neighborhood, built around Mission Dolores in 1776 and home to a continuous Latino community since the 19th century. The Mission District neighborhood guide covers its full history, murals, and what to do while you're there.
Do I need to wear calavera makeup? No. Calavera makeup is a theatrical costume whose roots are in the Catrina — a 1913 satirical lithograph by Jose Guadalupe Posada depicting a skull in European aristocratic dress. If you choose to wear it, know what it references. You do not need it to attend or be welcomed at any public celebration.
Can I photograph the altars? At public events, yes — community ofrendas are built precisely to be witnessed. When in doubt, ask. Private family altars at cemeteries are different; treat them with the same courtesy you would give any graveside gathering.
Should I bring anything? Marigolds (cempasuchil) are welcomed at any public celebration. Any grocery store carries them in late October. Placing a bunch near an ofrenda is participation, not intrusion. Some public events also have areas where visitors can leave offerings of food or flowers — check the event details.
Is this only a Mexican tradition? Dia de los Muertos originated with Nahua peoples of central Mexico, but similar ancestor-honoring traditions exist across pre-Columbian Mesoamerica. In the US it is primarily celebrated by Mexican and Mexican-American communities, and public events in cities like Los Angeles, Chicago, and San Francisco are genuinely open to anyone who comes to observe and learn.
What's the best day to go? November 1 and 2 are the core days. Altars and exhibitions in the days before tend to be less crowded and more accessible. The night of November 2 draws the largest public gatherings at cemetery and procession events — arrive early and plan for crowds.
