Our other Williams guides cover the town regardless of the calendar -- the depot's history, Bill Williams Avenue, the mountain trail. This page is different: it's the list of dated, organized events that happen in Williams itself, verified against each event's own current listing rather than assumed from a template.
Worth saying up front, because Williams sits almost exactly between two much larger event calendars: the Grand Canyon's South Rim is about an hour north on AZ-64, and Flagstaff is about 32 miles east on I-40, and both already have their own dedicated events guides on this site. The Grand Canyon Star Party, the Grand Canyon Music Festival, and the park's other ranger- and concessioner-run programming are covered on our Grand Canyon events and festivals guide. The I Heart Pluto Festival, the Flagstaff Festival of Science, the Coconino County Fair, and Flagstaff's own Route 66-branded car show (the Mother Road Classic, formerly called Route 66 Days) are covered on our Flagstaff events and festivals guide. This page sticks to what's actually organized in Williams: downtown along Bill Williams Avenue, the Williams Rodeo Grounds, Buckskinner Park, and the historic depot itself.
Eight things make up Williams' real annual calendar below, running from a June car show through a New Year's Eve street party. The clearest pattern: Williams' events lean hard into the identity this network's Williams hub guide already covers in depth -- the town's own Route 66 bypass history, its railroad depot, and its namesake mountain man, William Sherley "Old Bill" Williams. We cover what each event actually is, whether it's genuinely annual or still finding its footing, and where to verify current details before building travel around any of them.
Williams Historic Route 66 Car Show (Early June)
Hosted by American Legion Cordova Post 13, this is Williams' own flagship car show and its 11th annual run in 2026, held June 5-6 in downtown Williams along the town's own stretch of Route 66. Friday evening (June 5, 5 PM) is the "Cruise the Loop" parade, with entrants circling the loop formed by Route 66 and Railroad Avenue; Saturday is the main judged show, with roughly 500-600 vehicle spots, live music, food vendors, and more than a dozen specialty awards including Best of Show and Traveled the Farthest. The 2026 theme, "A Century of Kicks on Route 66," marks the highway's 100th anniversary. It's free to attend as a spectator; vehicle registration for entrants is separate and fills up.
Worth being precise about here: this is a different event from Flagstaff's own Route 66 car show, the Mother Road Classic, which runs in August about 32 miles east. Both towns run their own Route 66-branded shows in this centennial year, which makes them easy to mix up if you're not tracking which town hosts which weekend -- see our Flagstaff events guide for that one.
Lowdown verdict: The single best pick on this page if Route 66 heritage is why you're visiting Williams at all -- pair it with our Williams Route 66 guide for the town's own bypass history. Book downtown lodging early; this weekend fills the town's relatively small room inventory.
Rodeo Season: Cowpunchers' Reunion & Williams Night Rodeo (Late June – August)
Williams runs a genuine working-cowboy rodeo tradition through the middle of summer, at the Williams Rodeo Grounds off Airport Road. The Arizona Cowpunchers' Reunion Rodeo is the older of the two -- its 48th annual run lands June 27-28, 2026, organized by the Arizona Cowpunchers Reunion Association specifically to keep alive the camaraderie of working cowboys and the livestock industry, with wild horse racing, wild cow milking, and team roping events built around that working-ranch tradition rather than a rodeo-circuit spectacle. The Williams Night Rodeo is newer -- launched in 2024 by Keith Family Rodeo Productions LLC, a family business owned and operated by Jason and Billi Jo Keith -- and runs Friday and Saturday nights at 7:30 PM from July 10 through August 22, 2026, with bull riding, barrel racing, and mutton busting for younger riders. Both require paid admission; confirm current Night Rodeo ticket pricing on the organizer's own ticketing site before you go.
Lowdown verdict: The Cowpunchers' Reunion is the one with real depth of history if a genuine working-ranch tradition is what you want; the Night Rodeo is the more casual, repeatable summer-weekend pick since it runs most Friday and Saturday nights across two full months. Confirm current dates on azcowpunchers.com and williamsnightrodeo.com, since both can shift.
Fourth of July: Parade, Fireworks & All-American Block Party
The City of Williams runs a full Independence Day slate downtown every year; the 2026 edition carries the theme "Taking It Back in Time," tied to the America250 anniversary, but the event itself is Williams' standing annual Fourth of July, not a one-off. Festivities start at 10 AM, the Freedom Fest Parade steps off at 6 PM with vintage floats and patriotic displays, and fireworks launch at 9 PM from the Sweetwater Well site north of I-40 between Airport Road and Grand Canyon Boulevard, visible from multiple points around town. The All-American Block Party runs alongside it at Cureton Park, with vendors, a dunk tank, cornhole and horseshoe tournaments, a kids zone, and a beer garden. Parade entry forms are due by June 20, 2026. It's free to attend.
Lowdown verdict: A genuinely easy, free, family-friendly Fourth of July that doesn't require fighting Grand Canyon or Flagstaff crowds -- worth building a trip around if the holiday timing works, and worth pairing with a stop at the depot since it's a short walk from most of the route.

Williams 3-Day Itinerary
Downtown, a full day at the Grand Canyon, and Bearizona or Bill Williams Mountain -- a base plan to build event days around.
See the 3-Day Plan →Williams Rendezvous Days (September)
This is the one event on this page with no equivalent anywhere else on this network. Rendezvous Days recreates the 19th-century American fur-trade gatherings where trappers and mountain men met once a year to trade, compete, and swap stories -- primitive shooting competitions, a traders' row of period vendors, interactive demonstrations, and a Route 66 street dance downtown. The 2026 edition runs September 18-20 at Buckskinner Park (S 6th Street) and downtown Williams. It's tied directly to the town's own namesake: Williams is named for Bill Williams Mountain, itself named for William Sherley "Old Bill" Williams, the 19th-century trapper and mountain man covered in depth on our Williams hub guide. It's free and family-friendly.
The same late-summer stretch also carries the George B. Wallace Memorial Mountain Man Run, a 10K/5K race on Labor Day (September 7, 2026) starting near the depot at 300 W. Railroad Avenue, with Coonskin hats awarded to the top three men and women in each distance -- a smaller, separate event tied to the same mountain-man theme, about two weeks ahead of the main Rendezvous weekend rather than the same day.
Lowdown verdict: If you only build one Williams trip around an event, make it this one -- it's the town's most distinctive calendar entry, genuinely tied to its own history rather than borrowed from a bigger neighbor, and it's free. Confirm current dates at route66centennial.org or the visitor bureau's listing before booking, since Rendezvous-style events can shift by a week or two year to year.
Route 66 JDM Classic Car Show (October)
A second, smaller car show fills October: the Route 66 JDM Classic, open to Japanese-market classic cars and trucks 2001 and older -- Datsun/Nissan, Honda/Acura, Toyota/Lexus, Mazda, Subaru, Mitsubishi, Daihatsu, Isuzu, and vintage Japanese motorcycles. The 2026 edition runs October 2-3 in Williams. Judging is informal and peer-based rather than a strict points system, and proceeds from registration, raffle tickets, and t-shirt sales benefit Encircle Families, an Arizona nonprofit supporting children with disabilities. It's free for spectators.
Lowdown verdict: A genuinely different crowd and car culture than the June show's American classics and hot rods -- worth knowing about specifically if JDM cars are your interest, since it's a smaller, more specialized event that doesn't get the same visibility as the June show.
The Polar Express at the Grand Canyon Railway Depot (November–December)
The single biggest annual draw to Williams, and the one most directly tied to the depot our Williams hub guide and Grand Canyon Railway guide cover in depth. The Grand Canyon Railway's Polar Express runs seasonal evening round trips from the 1908 Williams Depot, based on the children's book and film, with onboard hot chocolate and cookies served while the story is read aloud and Santa boarding to greet each child and hand out a commemorative silver sleigh bell. The 2026 season opens November 6-8 and runs select evenings through December 30, with departures at 5:30 PM and 7:30 PM on scheduled nights -- not every night in that window runs a trip. The round trip runs about 90 minutes. It's a paid, ticketed experience.
Lowdown verdict: Book well ahead -- this is Williams' highest-demand event by a wide margin, and popular dates sell out weeks before December. Downtown lodging fills alongside it, so pair a Polar Express night with the same trip rather than trying to book both separately at the last minute.
Holiday Tree Lighting & Parade of Lights (Late November)
A separate, free, community-run event from the Polar Express, held on the west end of Historic Route 66 rather than at the depot. The 2026 edition is scheduled for Saturday, November 28, starting at 6:30 PM, with the parade lineup near 9th Street and Route 66 and the route running east to Pine Street. The event includes a downtown tree lighting and "Santaland" programming for kids. It's free and open to the public.
Lowdown verdict: A low-key, free add-on if you're already in town for a Polar Express trip or an early-winter visit -- it's a genuine small-town holiday parade rather than a large production, and easy to combine with a downtown dinner.
New Year's Eve Car Drop (December 31)
Williams closes its year with a Route 66-themed twist on the ball drop: a classic car is suspended above a vintage gas station setup downtown and lowered at midnight. The December 31, 2025 edition dropped a restored 1927 Chevrolet Capitol, a nod to Route 66's 1926 founding year -- the specific car and theme change annually, so expect a different vehicle for the December 31, 2026 edition rather than the same 1927 model repeating. The evening runs roughly 8 PM to 12:30 AM with live music, a beer and wine garden, and a fireworks display at midnight. It's free.
Lowdown verdict: A genuinely distinctive, low-cost way to spend New Year's Eve if you're not chasing a big-city countdown -- confirm the current year's exact theme and car on the City of Williams' own event listing rather than assuming it repeats the prior year's details.
What We Left Off This List
A few things worth mentioning that didn't make the calendar above, and why. The clearest category is events that genuinely belong to a neighboring town rather than Williams itself: the Grand Canyon Star Party, the Grand Canyon Music Festival, the Grand Canyon Celebration of Art, Indigenous Peoples' Day programming at the South Rim, the park's Artist- and Astronomer-in-Residence programs, the Grand Canyon Trail Half Marathon and Rim2Rim races, and the park's Fee-Free Days are all Grand Canyon National Park events, roughly an hour north -- see our Grand Canyon events and festivals guide. The I Heart Pluto Festival, the Northern Arizona Book Festival, Pride in the Pines, the Museum of Northern Arizona's Heritage and Hopi Festivals, Flagstaff's Fourth of July programming, the Mother Road Classic car show, the Coconino County Fair, the Flagstaff Festival of Science, and the Flagstaff Star Party and Oktoberfest are all Flagstaff events, about 32 miles east -- see our Flagstaff events and festivals guide. We're naming both lists explicitly rather than letting either page silently duplicate the other's content.
We also found a "World Series of Team Roping Qualifier" listed for July 3-5, 2026 in Williams alongside the Night Rodeo season, and a separately named "Jack Fuller Roping Event," but couldn't confirm enough detail on either one's current venue, organizer, and recurrence to present them as a verified annual listing rather than a single aggregator mention -- search current listings directly before planning around either. And we found a "Route 66 Centennial Celebration & Classic Car Show" listing on the Coconino County events calendar that, as far as we can tell, describes the same June Historic Route 66 Car Show under its 2026 centennial theme rather than a separate one-time event -- unlike Flagstaff, which is running an actual standalone, one-time Route 66 Centennial Celebration on June 6, 2026 in addition to its own August car show. We're flagging that distinction because it's easy to assume Williams has a similar one-off event when what we found points to the same annual show being centennial-themed this year.
Confirm Before You Book
The pattern worth internalizing from this page: Williams' calendar clusters around three anchors -- a June-through-August run of car shows and rodeos, a September Rendezvous weekend tied to the town's own namesake, and a November-through-December stretch built around the depot's Polar Express and two separate holiday street events. Several entries here carry a real 2026 centennial flavor -- the June car show's "Century of Kicks" theme and the New Year's Eve Car Drop's Route-66-anniversary framing -- worth knowing about if you're comparing this year's programming to a future one. Go straight to the organizer for each: williamshistoricroute66carshow.com for the June show, route66jdm.com for October, azcowpunchers.com and williamsnightrodeo.com for the two rodeos, thetrain.com for the Polar Express, and the City of Williams' and experiencewilliams.com's own event listings for the Fourth of July, Rendezvous Days, the Holiday Parade of Lights, and the Car Drop.
Building a Trip Around One of These Events
Rendezvous Days in September is the strongest single pick if you want an event genuinely unique to Williams -- it's free, it's tied directly to the town's own history covered on our Williams hub guide, and September's cooler high-country weather (Williams sits at roughly 6,770 feet) is a comfortable window for the rest of a trip. If a bigger, more reliably dated draw is what you want, the Polar Express season gives the most name recognition and the deepest tie to the depot itself, though it also books up furthest in advance. See our 3-day Williams itinerary for how to build days around downtown, a Grand Canyon day trip, and Bearizona regardless of which event weekend you land on, and our getting around Williams guide for what's walkable downtown once street closures are in effect for a parade or car show.
If your real interest is a Grand Canyon-specific event like the Star Party or the Music Festival, or a Flagstaff-specific one like the Festival of Science or the Hopi Festival, plan the trip around that town directly rather than Williams -- see our Grand Canyon events guide and Flagstaff events guide. And for the depot's own year-round history rather than its holiday-season programming, our historic downtown Williams guide and Grand Canyon Railway guide cover far more depth than a calendar entry could.
