San Dimas in October: The Two-Week Overlap That Runs the Whole Fall

Ask a newcomer what happens in San Dimas in October and they will say Western Days. Ask someone who has lived here through three or four of them and the answer gets more specific. They will tell you which morning to be at Civic Center Park, which taproom stays quiet the night the parade rolls through, and why the first weekend of the month feels like two towns operating on the same block at the same time.

That overlap is the point. San Dimas in fall isn't a single festival weekend inside an otherwise quiet month. It's a two-week stretch where the rodeo grounds at the north end and the walkable Bonita Avenue core each pull in a different crowd, and the residents who know how to move between them get the best version of the season.

The two Octobers that overlap

The Western Days weekend has been an October fixture for more than three decades. The PRCA Pro Rodeo has run at Horsethief Canyon Park in San Dimas, celebrating its 21st anniversary in 2015, which makes 2026 somewhere north of its 31st year. The main PRCA competitions take place each day at 2:00 p.m. on the grounds of Horsethief Canyon Park, with gates opening at 11:00 AM and events and shows starting at 1:00 PM.

That's the north end of town. What most residents overlook is that downtown Bonita Avenue runs a parallel event on the same October weekend, and it has almost nothing to do with the rodeo.

The rodeo arena at Horsethief Canyon carries the name of Tex Shoemaker, a former law enforcement officer and leather craftsman whose commitment to the city led the council to name the grounds in his honor. It is the closest thing San Dimas has to a civic monument, and most people who live here have never set foot inside it.

What actually happens on Bonita Avenue

The downtown side of the October weekend runs on a different tempo. The San Dimas Beer & Wine Walk 2026 is happening on Saturday, October 3, 2026 from 3:00 PM onwards in Downtown, San Dimas. It is the same day the community parade traditionally kicks off, and the two events braid together across a six-block stretch.

The parade route matters if you live on any of the streets that touch it. The parade kicks off at Gladstone and San Dimas Avenue, goes south to Bonita Avenue, then west to Cataract Avenue. If your morning commute crosses any of those intersections, plan on the closures starting well before the 10 a.m. step-off.

A few things worth knowing about the weekend on Bonita:

• Craft, food, and business vendors line the street from mid-morning through evening on Saturday, with a shorter run on Sunday.
• San Dimas offers multiple parking lots around the downtown area with both free and paid options. The free lots south of Bonita fill first; the ones north of the tracks stay open longer.
• Live music runs on the downtown stage during the same hours the rodeo is running two miles north. You can hear both if you time it right.
• Historical demonstrators and the Kid's Fun Zone anchor the middle of the block, which is where most of the foot traffic bottlenecks.

Arrow Highway keeps its own hours

The third geography of October in San Dimas is Arrow Highway, and specifically Highpoint Brewing Company at 402 W Arrow Hwy. It started a decade ago at the base of the San Gabriel Mountains on a street called Highpoint, where Chad Phillips and Dominic Torres began brewing for their friends and family. As the first brewery in San Dimas, the owners strive to bring a high quality product with complex flavors in a casual environment.

Here is the local move most residents miss. Highpoint's hours run Monday through Friday from 4:00 pm to 10:00 pm, and Saturday from 12:00 pm to 10:00 pm, and Sunday from 12:00 pm to 8:00 pm. That schedule matters during Western Days weekend because the taproom is at its calmest exactly when downtown is at its most crowded. If you want to see the parade and then eat somewhere that isn't a folding-table barbecue booth, walking away from Bonita is the answer, not toward it.

The other detail worth flagging: Highpoint is a taproom, not a full kitchen. Pair it with a Twisted Pig Pretzels order next door and the equation works.

Weekend map for the fall stretch

The rhythm of the month is easier to see when you lay it out by weekend. The dates below reflect what the city and the event organizers have already published for fall 2026, plus the annual patterns that hold year to year.

The Civic Center Park morning event on September 26 runs from 7:30 to 10 a.m. at 245 E. Bonita Ave. That is the same address as City Hall, which means the parking is limited and the surrounding side streets fill fast.

The morning that quietly anchors the whole month

If you had to pick a single hour that tells you fall has actually started in San Dimas, it isn't the parade step-off. It is that Saturday morning at Civic Center Park at the end of September, one week ahead of Western Days. The event serves as a soft-launch for the downtown season. Vendors who will be on Bonita a week later show up here first. Neighbors who ordinarily wave from driveways end up talking for twenty minutes on the lawn. By the time you leave, you know what the next weekend is going to look like.

It is also a useful thermometer for the year ahead. If Bonita is packed at 8 a.m. on the 26th, the Beer & Wine Walk is going to be a scrum. If it is loose and easy, you can plan on walking up to the wristband table on the 3rd and still finding one.

Fall after the rodeo leaves town

The mistake most residents make is treating the second half of October as a lull. It isn't. It is the best two weeks of the year to use the trail systems that bookend the city on the north and south.

San Dimas Canyon Park sits at 1628 N. Sycamore Canyon Road and opens into the foothill trail network above the reservoir. The morning fog that rolls off the San Gabriels burns off by nine most days in October, which gives you a two-hour window that is cooler than August and drier than November.

On the south end, Frank G. Bonelli Regional Park handles the lake-oriented crowd. Puddingstone thins out dramatically the second the rodeo weekend ends, and the loop road becomes a legitimate walking and cycling option through Thanksgiving.

For the indoor half of the calendar, two spots do more work than most residents give them credit for. Bonita Center for the Arts hosts community performances and choir programs into the fall; the King David Choir performs there on Sunday, September 6, 2026 at 6:00 PM. And Judging By The Cover, the independent bookstore on the downtown corridor, runs weeknight programming that fills the gap between the October festival crush and the December holiday events.

Why this window matters if you live here

The two-week overlap in early October is the most compressed civic calendar San Dimas has all year. Every downtown business, every vendor booth on Bonita, every food truck that will circulate through the fall shows up in that window. If you have lived here long enough to have a favorite spot, this is when you find out who your new favorites are going to be.

It is also the window where residents notice each other. The same neighbors who nod at the mailbox in July end up sitting three feet apart on the curb watching the parade. The couple three houses down turns out to be at the same rodeo section on Saturday afternoon. Something about the geography of the weekend, the way the rodeo grounds and Bonita Avenue pull opposite ends of the same crowd, makes the town feel smaller in October than it does the other eleven months.

That is worth planning around. Block the first weekend of October. Skip the second weekend if you can, because everyone else in town is going to be recovering. Then use the back half of the month for the trails and the taproom and the bookstore, which is where the season actually settles in.
