Most years, Cupertino spreads its fall traditions out so residents can hit all of them without much planning. Not this year. On Saturday, September 12, 2026, the Striders Reservoir Run kicks off at 9 a.m. at Stevens Creek County Park, and by afternoon the Rotary Club of Cupertino's Silicon Valley Fall Fest is setting up craft beer tasting booths and a fine arts show across town at Memorial Park. Two of the city's longest-standing fall gatherings, same Saturday, different ends of the day.
It's a scheduling quirk, not a conspiracy, but it's worth noticing because it says something about how this city actually spends its autumn. Cupertino's fall calendar isn't one thing. It splits cleanly into a trail-and-creek half and a town-square half, and this particular Saturday happens to put both halves on the same page.
A Saturday With Two Start Times
The Striders Reservoir Run offers an 11k and a half-marathon option, both starting from the Villa Maria Picnic Area inside Stevens Creek County Park. It's the kind of event that draws people who already know the park's fire roads from weekday training runs. No costumes, no vendor booths, just a 9 a.m. start line and a course built around the reservoir itself.
Fall Fest runs on a completely different register. The Rotary Club of Cupertino has staged this event at Memorial Park for 40 years, and Fall Fest 2026 is expected to draw roughly 5,000 people over the course of a single day. Current programming includes a fine arts show, gourmet food trucks, a craft beer tasting booth, live entertainment from District XVII, and a Bike Rodeo run in partnership with the De Anza Optimist Club, alongside an expanded Kids' Zone with pony rides, a petting zoo, giant slides, and a wild animal show. It's a fundraiser first: every dollar raised goes toward the Rotary Club's yearly charitable projects in the local community, which is part of why the event has lasted four decades without needing a rebrand or a new location.
So the day starts quiet, along a reservoir trail with a few hundred runners, and ends loud, with several thousand people wandering a fairgrounds built inside a city park. If you only have room for one of the two on your calendar, that contrast is worth factoring into which one you pick.
The Creek That Keeps Showing Up
Stevens Creek is the thread that connects more of Cupertino's outdoor life than most residents track consciously. The reservoir behind the Striders Run course is formed by the same creek that later runs directly through Blackberry Farm, downstream and closer to the center of town. Blackberry Farm connects into the Stevens Creek Trail network, the same route that threads walkers, joggers, and cyclists through several neighboring communities.
The farm's name predates the city itself. In 1848, a South Carolina-born blacksmith and trapper named Elijah Stephens settled at the base of Black Mountain on what was then called Cupertino Creek and established a 160-acre homestead he called Blackberry Farm. Stephens is a genuine footnote in California history: he led the Stephens-Townsend-Murphy Party, the first wagon train to cross the Sierra Nevada successfully, two years ahead of the ill-fated Donner Party. He sold the property in 1864 to George McCauley and William McClellan, reportedly grumbling that the area was getting "too durn civilized," and moved on to Kern County.
The City of Cupertino has owned and managed the site's nine-hole golf course since 1991, a compact par-29 layout with narrow, tree-lined fairways running alongside the same creek. That long municipal ownership is part of why the park still functions as a creek-corridor hub rather than getting carved up for other uses. It's also part of why Wildlife & Harvest Day, described below, has had a stable home for years.
Where the Birds Show Up Once October Arrives
Every October, the Santa Clara Valley Audubon Society partners with the City of Cupertino to host Wildlife & Harvest Day at Blackberry Farm, just down the road from the Audubon Society's own headquarters at McClellan Ranch Preserve. In past years the event has landed in the middle of the month, with the 2018 and 2019 editions both held in the 10 a.m. to 3 p.m. window on a Saturday around October 19 or 20. This year's exact date hasn't been posted yet, but the pattern is consistent enough that residents who circle mid-October on their calendars rarely miss it.
The festival leans hard into hands-on programming rather than passive spectating. Past years have included an early-morning guided bird walk, held not at Blackberry Farm itself but at Charleston Slough in Mountain View, with participants driving over afterward to join the main festivities. Once on-site, visitors can build nest boxes and bird feeders for a small materials fee, watch a live raptor presentation featuring a Harris's Hawk, catch a Big Cats demonstration from the Wild Cat Education & Conservation Fund, or walk alongside goats and ponies in the Rolling Hills 4-H costume parade. General admission has always been free.
What makes this festival worth knowing about, beyond the animals, is what it says about the creek corridor as a whole. McClellan Ranch Preserve, Blackberry Farm, and the broader Stevens Creek Trail aren't separate amenities that happen to sit near each other. They function as one continuous stretch of habitat and public land, and the Audubon Society's decision to headquarter there says something about how much wildlife actually still moves through this part of Cupertino despite the density of tech campuses a few miles in every direction.
Main Street Doesn't Wait for the Weather to Turn
While the creek side of Cupertino runs on seasonal festivals, the town-square side keeps a weekly rhythm going year-round. Main Street Cupertino, the open-air plaza on Stevens Creek Boulevard near Apple Park, has kept its Friday night live music series running into September 2026. Grace & The Grit played the plaza on September 4, part of a lineup that continues to bring acoustic and rock acts to the square through the fall.
The plaza itself has become a genuine dining cluster rather than a single anchor tenant with a few side shops. A short walk covers:
- Lazy Dog Restaurant & Bar, for American comfort food
- Alexander's Steakhouse, open since 2005 and one of the longer-tenured restaurants in the plaza
- Eureka!, known locally for its burger menu
- Philz Coffee, for the morning crowd before the shops open
- Ippudo and Koi Palace, both part of the plaza's deeper bench of Asian dining options
None of this requires a festival date on the calendar. It's simply what a Friday night in Cupertino looks like now, walkable, lit up after dark, and busy enough that parking structures see more traffic than the street spots out front.
Picking Your Own Version of Fall
None of this means residents need to choose a side and stick with it. The reservoir run happens once a year. Fall Fest happens once a year, on the same Saturday this time. Main Street's music series happens every Friday through the season, and Wildlife & Harvest Day will land sometime in October whether or not the exact date has been posted yet. The point isn't to pick a lane. It's to notice that Cupertino's fall calendar has two genuinely different characters sharing the same nine or ten square miles, one built around a creek that's been running since long before the city existed, and one built around a plaza that's newer than most of the landmarks around it.
Both are worth your Saturday. This year you just have to choose which one gets your morning.
