Late October and early November bring two very different celebrations to Arizona. Halloween, on Saturday, October 31, is a night of costumes, treats, and playful frights. Día de los Muertos, observed November 1 and 2, is a Mexican tradition of honoring and remembering loved ones who have died, with altars, marigolds, music, and processions. Each deserves its own attention, so this guide covers them separately, with notes on which events suit a quieter pace.
Halloween Events
Phoenix and the Valley
McCormick-Stillman Railroad Park in Scottsdale (7301 E. Indian Bend Road) hosts Halloween Spook-Track-Ula, running from October 10 through October 31, 2026, billed as family-friendly with a spooky but not terrifying atmosphere, and requiring paid admission. It’s a good outing for grandparents bringing young grandchildren, since the train and carousel rides keep things gentle.
The Arizona State Fair is still going this weekend. The 2026 fair runs through November 1 on Thursdays through Sundays at the Arizona State Fairgrounds in Phoenix, so Halloween weekend is your last chance to catch it. Daytime visits are calmer and less crowded than evenings.
For grandparents with toddlers, the City of Phoenix is hosting the Itty Bitty Boo Bash on Saturday, October 31, from 10 a.m. to noon; it’s free, but registration is required. It takes place at South Mountain Community Center, 212 E. Alta Vista Road, with candy, crafts, music, games, and snacks.
Tucson and Southern Arizona
The Southern Arizona Transportation Museum in downtown Tucson will hold its annual Halloween Party on Saturday, October 31, 2026, at 414 N. Toole Avenue. The museum’s railroad history makes it an easy, low-key stop for all ages.
Old Tucson’s Nightfall wraps up this weekend. The 2026 event runs select Thursdays through Sundays through October 31, from 5 p.m. to 11 p.m., with tickets at oldtucson.com. Nightfall is a true haunted attraction with scare zones and mazes, so it’s best for those who enjoy a fright. Old Tucson also offers guided ghost tours, a calmer way to enjoy the site’s spooky legends.
In Cochise County, Tombstone has a tradition of a community Halloween night trunk-or-treat. In 2025, city offices closed early so the Fire Department could set up its Trunk or Treat at Discover Tombstone Field. Contact the City of Tombstone to confirm this year’s details.
Northern Arizona
Downtown Flagstaff holds a free Halloween Trick-or-Treat Trail each year in Heritage Square and the surrounding downtown area, traditionally on Halloween afternoon. It’s a pleasant way to enjoy cool mountain air and watch the costumes go by. Visit downtownflagstaff.org for this year’s hours.
In Clarkdale, Verde Canyon Railroad has hosted its Fright Night haunted train at the depot each fall through Halloween. The haunt itself is intense, but the railroad’s scenic canyon rides are a wonderful autumn outing on their own. Call ahead for current schedules.
Yuma
Arizona State Parks lists a Halloween evening event at Yuma Territorial Prison State Historic Park called Cell Block Lock-In: Halloween in Prison, a fun choice for history lovers. Confirm the 2026 date and time with Arizona State Parks before you go.
Halloween at Your Local Senior Center
Many of the best Halloween gatherings for older adults happen close to home. Scottsdale’s Via Linda Senior Center has hosted a Halloween Bash in past years; the 2025 event featured a luncheon, raffle prizes, a costume contest, and party favors for $10 for residents and $13 for non-residents. Call Via Linda Senior Center at 480-312-5810 to ask about this year’s plans. Chandler residents can find the Downtown Chandler Senior Center’s monthly activity calendar at chandleraz.gov/senior-adults. Wherever you live, a quick call to your local senior center may turn up a costume party, potluck, or bingo afternoon this week.
Día de los Muertos Events
Día de los Muertos is a time to welcome back the memory of those who have passed. Families build ofrendas, or home altars, decorated with photographs, candles, marigolds, and the favorite foods of the departed. For many older Arizonans, these gatherings offer a meaningful way to honor a spouse, parent, or friend, and the public events below welcome everyone, whatever their background.
Phoenix and the Valley
On Sunday, November 1, the Phoenix Zoo will hold a Día de los Muertos celebration that pairs a zoo visit with cultural programming; check admission details and the schedule before going.
The Desert Botanical Garden’s Día de Muertos Festival is one of the most senior-friendly events of the season. An altar exhibit runs November 6 through 9, with the main festival on Saturday and Sunday, November 7 and 8, from noon to 6 p.m. A memorial procession is scheduled at 5 p.m. each festival day, and activities are included with general admission or membership. The garden’s paths and the early-November weather make this a comfortable outing.
Tucson
Tucson’s All Souls Procession is one of the largest remembrance events in the country and is inspired by Día de los Muertos. The 37th annual event returns in November 2026. Participants gather at 4 p.m. on Grande Avenue near Speedway Boulevard, with the procession departing at 6 p.m. and ending in the Mercado District with a finale that includes the ceremonial burning of an urn filled with messages and offerings for the departed. The event is free. Crowds are large, so many older adults choose to watch from a spot along the route rather than walk the full two miles. Check allsoulsprocession.org for the confirmed date.
Honoring Loved Ones at Home
You don’t need to attend a festival to take part. Setting up a small ofrenda at home with a photo, a candle, and a few marigolds is a simple, personal way to remember someone dear. Many senior centers, churches, and libraries also host altar-building or remembrance activities in early November, so it’s worth asking locally.
Tips for Getting Out This Season
Choose daytime events when possible. They tend to be less crowded, easier to navigate, and better lit.
Dress in layers for evening events. Desert nights cool off quickly this time of year, and higher-elevation towns like Flagstaff and Prescott can be cold after sunset.
Bring a folding chair or stool to processions and outdoor festivals, and plan your parking or drop-off spot ahead of time.
Call ahead about accessibility. Ask about wheelchair access, paved paths, restrooms, and seating before you buy tickets.
If you’re staying home for trick-or-treaters, keep your porch and walkway well lit, clear away anything that could cause a trip, and keep pets safely away from the door.
Whether you’re enjoying a festive lunch with friends, a train ride with the grandkids, or a quiet evening honoring loved ones at an altar, this season in Arizona offers something for every comfort level. Event details can change, so always confirm dates, times, and prices with organizers before heading out.
