Cupertino and its neighbors spent years running an actual experiment on how to fix weekend parking at Rancho San Antonio. There was a pilot program, a consultant's report, survey data on ride-hail preferences, and a multi-agency task force that included the cities of Cupertino, Los Altos, Los Altos Hills, Mountain View, and Sunnyvale along with Santa Clara County Parks and the VTA. In April 2024, the agency that ran it, the Midpeninsula Regional Open Space District, voted not to move forward with a subsidized shuttle or ride-hail program at all.
Nothing replaced it. And yet if you talk to anyone who hikes Rancho on a regular Saturday, they will tell you exactly how to get a parking spot. That knowledge did not come from the county. It came from residents solving the problem themselves while the official fix quietly stalled out.
The Access Project That Never Shipped
Rancho San Antonio is Midpen's busiest preserve, and it shows on any given weekend morning. The district's response, formally called the Rancho San Antonio Multimodal Access Project, started with a 2020 study identifying congestion at the preserve's six lots off Cristo Rey Drive. The most visible piece of that plan was a carpool pilot: starting in September 2022, Lot 1 at the Coyote Trail trailhead, the main 80-space lot closest to the restrooms and the Deer Hollow Farm trail, was restricted to vehicles carrying three or more people on weekends and holidays.
The pilot ran for one year. When Midpen closed it out and reported the results, the numbers were specific. Enforcement was active on 109 days. The carpool lot hit full capacity on 26 of those days and exceeded 90 percent capacity on 63 more. That means on more than eight of every ten enforced days, the lot the county had set aside specifically to reduce solo driving was itself nearly or completely full.
The board's response was to ask staff to keep studying long-term options. What came out of that follow-up work, by April 2024, was a decision not to fund a subsidized ride-hail program and not to build a dedicated shuttle. The carpool requirement itself lapsed. Today Midpen's own parking page tells visitors that carpool rules at Rancho San Antonio are suspended until further notice, while still encouraging carpooling whenever people can manage it on their own.
What Survived the Rollback
Not everything from the access project disappeared. A few pieces are still in place and worth knowing before you load the car.
An electronic signboard at the preserve entrance shows real-time space counts across the lots, and the same numbers are posted online at openspace.org/rsa-parking so you can check from your kitchen before you leave. A designated rideshare drop-off zone was added near the restrooms in the main parking area, which matters if you are getting dropped off rather than parking. Bike racks were added at the Mora Trail entrance, the Deer Meadow Trail entrance, and the open-air barn at Deer Hollow Farm, plus a repair station in the main lot.
The other survivor is Silicon Valley Hopper, the on-demand shared-ride service that grew out of the earlier Via-Cupertino shuttle. It is not subsidized specifically for Rancho San Antonio, but it does list the preserve as a stop, running from anywhere in Cupertino and southern Santa Clara plus the Mountain View, Sunnyvale, and Santa Clara Caltrain stations, at a fare that has run around $3.50 per ride, half that for youth, seniors, and riders with disabilities. It is a real option. It is just not the dedicated shuttle the multimodal study once floated.
The Six Lots, In the Order They Actually Fill
If you are driving in, the order matters more than the total count. Here is how the county park's own posted lot sizes break down along Cristo Rey Drive:
| Lot | Spaces | Notes |
|---|---|---|
| Lot 1 (Coyote Trail trailhead) | 80 + 4 ADA + 2 equestrian | Closest to restrooms and Deer Hollow Farm trail; fills first |
| Lot 2 | 48 + 1 ADA | |
| Lot 3 | 22 + 2 ADA | |
| Lot 4 | 46 + 2 ADA | |
| Lot 5 | 30 | |
| Rhus Ridge (north end, separate from the main entrance sequence) | 9 + 1 ADA | Reached via Foothill Boulevard and a short section of Cristo Rey Drive; often overlooked |
Lot 1 fills first because it sits closest to the amenities most casual visitors want, the bathrooms and the flat farm walk. Once it is gone, the electronic signboard becomes genuinely useful, because it lets you decide from the entrance whether to loop toward Lots 4 and 5 rather than crawl the full length of the park road only to find nothing. Rhus Ridge, with just nine spaces, rarely gets mentioned in general guides because it is not part of the main entrance flow, but locals who know the preserve treat it as a legitimate backup on a Saturday when the main lots are already gone by nine.
The Route Around the Lots Entirely
There is a second workaround that has nothing to do with the six numbered lots, and it is the one that experienced Rancho regulars actually rely on most. A pedestrian and bike entrance connects under Interstate 280 near the Los Altos side of the preserve, off Mora Drive, feeding directly into the Mora Bike Path and the trail network beyond it. Park on the residential streets near the end of Mora Drive, walk or bike in, and you skip the numbered lots and the signboard entirely.
Cupertino has also been building toward safer bike access on Cristo Rey Drive itself, which currently lacks the kind of protected lane the city has already installed elsewhere. The city's Bicycle Pedestrian Commission has been working through options for physically separated bike lanes along the corridor, following the same approach Cupertino used on McClellan Road, on Bubb Road between McClellan and Stevens Creek, on Mary Avenue north of Stevens Creek Boulevard, and on the protected sections of Stevens Creek Boulevard itself east of Wolfe Road. None of that is finished on Cristo Rey Drive yet, but it signals where the city's actual investment is going, which is toward making the bike-and-walk-in option safer rather than adding car capacity.
If You Are Already Too Late
Say it is 9:30 on a Saturday and every lot from Coyote Trail to Lot 5 is showing full on the signboard. The preserve still has more than 20 miles of trail, and a few routes reward the people who show up after the rush rather than before it.
The Rogue Valley Trail is the easiest option, a roughly 3-mile beginner loop that avoids the crowded farm path. For more distance without serious climbing, the Chamise Trail runs about 5 miles out and back through the Duveneck pasture with a modest 400 feet of elevation gain. If you want the view that makes people come back, the PG&E Trail climbs about 1,600 feet over 4 miles, while pushing past the top of the Chamise Trail onto Black Mountain adds another 1,800 feet for the payoff, where the South Bay opens up below and San Francisco is visible on a clear day. Wildcat Canyon Trail stays shaded most of the way and loops back past Deer Hollow Farm, which makes it a good choice once the sun is higher.
A few rules apply no matter which trail you pick. Dogs are not permitted anywhere in the preserve, including the paved path to Deer Hollow Farm. The trail speed limit for cyclists is 15 miles per hour, dropping to 5 when passing hikers or horses. And if you do encounter a mountain lion, which has happened here, the guidance is to back away slowly rather than run.
What This Actually Tells You About Cupertino
The interesting part is not that parking is hard at a popular preserve. It is that the agencies responsible for fixing it studied the problem for years, built real infrastructure around the edges, and then declined to fund the one thing that would have solved it outright. What is left is a set of informal knowledge: which lot goes first, where the signboard lives online, which side street near Mora Drive gets you in on foot, and which trail rewards a later start.
That is a pretty accurate description of how a lot of shared infrastructure works in this part of the Peninsula. The formal process runs its course, the big fix does not always clear the finish line, and the neighborhood adapts around it anyway. If you already live near Rancho San Antonio, you have probably absorbed most of this without ever reading a Midpen report. If you are still getting to know the rhythms of your own corner of Cupertino, from trail parking to which streets get quiet after 9 a.m., that kind of local pattern-reading is exactly what Bay Area Home Sales spends its time on. Reach out any time you want a longtime Peninsula perspective on how a neighborhood actually works, not just what the map shows.
