The Castro Valley Fall Festival closes down Castro Valley Boulevard between Redwood Road and Santa Maria Avenue every September, and if you've lived here more than a few years, you already know the shape of it: corn dogs, kettle corn, two stages of live music, a kids' zone, more vendor tents than parking spots. This year marks the 54th time it's happened, on Saturday, September 12 from 10 a.m. to 6 p.m. and Sunday, September 13 from 10 a.m. to 5 p.m., free admission, same stretch of Boulevard it's occupied for decades.
The festival itself hasn't changed much. What's changed is everything around it.
In the twelve months since last year's festival, a 28,000-square-foot Cantonese banquet hall opened three blocks from where the vendor tents will stand. A Saturday farmers market that used to be a quiet stop for produce has settled into a full weekly rhythm. The Marketplace across the street started a monthly evening series that didn't exist two years ago. And for the first time, a volunteer group focused on Castro Valley's unincorporated status will have a booth inside the festival footprint, which tells you something about what residents are actually asking each other these days. If you're planning your weekend around the same festival you remember, you're planning around a Boulevard that's already moved on without you.
The Restaurant That Changed the Math
HL Peninsula opened in the former Rite Aid building on Castro Valley Boulevard last October, and it is not a small addition. At 28,000 square feet with seating for close to 900 guests across a main hall and nine private banquet rooms, it's the fifth Bay Area location for the Cantonese chain and, by capacity, the largest one they've built. For comparison, the location that previously held the size record for the company, in Milpitas, seats around 700. This one was designed to be the flagship.
The restaurant sits next to Mei Mei Market, a new grocery store that opened around the same time, and together the pair turned a stretch of Boulevard that had sat as vacant retail since Rite Aid closed in 2023 into a real anchor. Before Ming Y Li's project got Alameda County approval in August 2024, neighbors speculated about everything from a Sprouts to a car wash filling that space. What actually arrived pulls a different kind of visitor than the storefronts around it ever did on their own: people driving in from Fremont, San Leandro, and Hayward for weekend dim sum, then parking once and wandering the rest of the block while they wait for a table.
That waiting matters if you're planning a visit. Weekday lunch runs 10:30 a.m. to 2:30 p.m., weekend lunch runs 10 a.m. to 2:15 p.m., and dinner is served nightly from 5 to 9:30 p.m. A Sunday walk-in at noon behaves less like a stop on Castro Valley Boulevard and more like a wait at one of the big Milpitas dim sum halls. If you want a table without the hold, arrive at opening or come on a weekday instead.
A Saturday Routine That Was Never Really About the Festival
The Castro Valley Farmers' Market has run every Saturday, year-round, in the BART station parking lot at Redwood Road and Norbridge Avenue for longer than most of the Boulevard's newer businesses have existed. It runs from 9 a.m. to 1 p.m., accepts EBT with a dollar-for-dollar match up to $15 on fruits and vegetables, and it isn't going anywhere for the festival weekend. It's simply one more fixed point in a week that now has several.
The newer fixed point is First Fridays at the Castro Valley Marketplace, at 3295 Castro Valley Boulevard, across the street from HL Peninsula. The series started in 2024, produced by the Marketplace's management with its merchants and curated by Arté's Joanne Tan and Keesa Ocampo, and it puts small makers, food vendors, local artists, musicians, and DJs into the same space every month. Two years ago that space had no evening programming at all. Now the roster of what's inside the Marketplace has had time to settle, and the monthly event gives residents a reason to be there on a Friday night even in months with nothing else going on.
Put those two together with the festival weekend and you get a Boulevard that has three separate, recurring reasons for people to show up, not one annual reason. That's the actual shift. The festival used to be the exception that proved how quiet the rest of the year was. Now it's the loudest weekend in a calendar that already has a pulse.
Why the Festival's Food Lineup Looks Deliberate, Not Random
If you've ever noticed that the Fall Festival's food vendors never seem to compete directly with the restaurants already on the Boulevard, that's not an accident. The Castro Valley and Eden Area Chamber of Commerce, which presents the festival, scouts other regional street fairs for vendors worth recruiting, and the selection process is built specifically to avoid duplicating what the Boulevard's existing restaurants already offer. Last year's lineup leaned on fair-food specialists like Corn Dog Express, Bizuri Ice Cream, and Island snow cones, alongside local vendors such as Concha Dreams for bread, SweetCanes for juice, and Iron Horse Kettle Corn.
The effect is that the festival adds to the food scene for two days instead of pulling business away from it. If HL Peninsula, the Marketplace's food stalls, and the rest of the Boulevard's restaurants had to compete with festival tents selling the same kinds of food, the two days would cannibalize the other 363. Instead they layer on top of each other, which is part of why the Boulevard can support both an annual festival and a growing weekly and monthly calendar without either one cannibalizing the other.
The Booth You Won't Find at Most Street Fairs
This year's festival will include something that has nothing to do with food or music. Castro Valley City Inc., the volunteer campaign pushing to incorporate Castro Valley as its own township, is setting up an information booth inside the festival grounds. Castro Valley is currently unincorporated, which means decisions about land use, local budgets, and community services run through Alameda County rather than through anything residents vote on directly. The campaign has been building momentum for a while, with a related meeting at the Castro Valley Library drawing roughly 300 attendees this past July, and the Fall Festival booth is their attempt to reach people who wouldn't otherwise show up to a public hearing.
You don't need to have an opinion on incorporation to notice what this says about where the neighborhood's attention currently sits. A civic campaign choosing the Fall Festival as its outreach venue, rather than a standalone town hall, is a bet that residents are more reachable at the festival than almost anywhere else on the calendar. That's worth knowing whether or not you stop at the booth.
The Rest of the Rotary's Year
The same civic infrastructure that runs the Fall Festival has been busy in other months too. The Castro Valley Rotary Club held its third annual Whiskey Tasting and Charity Dinner on February 28 at The Breakfast Club at Midtown, and its 18th Annual Classic Car Show ran June 20 from noon to 5 p.m. in Downtown Castro Valley. Neither event is new exactly, but stacked together with the Marketplace's First Fridays and the farmers market's weekly cadence, they paint a Boulevard that has moved from a handful of good standalone businesses to a calendar with something happening most months, not just one weekend in September.
What This Actually Means for Your Weekend
If you're deciding how much time to give the festival this year, here's the practical version of everything above:
- The festival itself runs Saturday 10 a.m. to 6 p.m. and Sunday 10 a.m. to 5 p.m., free, on Castro Valley Boulevard between Redwood Road and Santa Maria Avenue.
- If you want HL Peninsula without a wait, go before 10:30 a.m. or pick a weekday instead of festival weekend.
- The farmers market at the BART lot runs its normal Saturday hours regardless of the festival, so you can still do your regular grocery run before heading over.
- If land use and local governance interest you, the Castro Valley City Inc. booth is worth five minutes even if you're undecided on incorporation.
- The next First Friday at the Marketplace will land on its usual schedule the week after the festival wraps, so if you miss it this weekend there's another chance soon.
None of this changes what the festival is. It changes what it's sitting inside of. A Boulevard with one big weekend a year reads differently than a Boulevard with a weekly market, a monthly evening series, a flagship restaurant pulling in regional traffic, and a civic campaign that thinks the festival crowd is worth talking to. That's the Castro Valley Boulevard you're actually walking into this year, whether or not anyone's pointed it out to you yet.
If you're a Castro Valley homeowner curious how any of this neighborhood momentum, from HL Peninsula's regional draw to the Marketplace's growing evening calendar, might be shaping what your home is worth right now, that's a separate conversation worth having.
