"the residents of Santa Rosa Valley lobbied to develop the Santa Rosa Valley Equestrian Park in Hill Canyon"
That's how longtime resident Rosemary Allison sums up three decades of her neighborhood's history in a single sentence. It explains something most people riding, walking, or picnicking at the Santa Rosa Valley Equestrian Park today never stop to ask: who actually built this place?
The honest answer isn't a parks department working from a master plan. It's a specific list of neighbors who spent thirty years asking for the park, then a handful of Saturdays actually building it, before the 50-acre site in Hill Canyon ever opened to a single horse trailer.
A Park That Sat on the Wrong Side of a City Line
Santa Rosa Valley is unincorporated Ventura County, but the Hill Canyon site sits right against the Thousand Oaks border. That geography turned what should have been a straightforward county park project into a negotiation between two separate governments. For decades, the Santa Rosa Valley Municipal Advisory Council pushed the idea forward, with members Rosemary Allison, Ruth Means, and Mark Burley logging what Allison describes as countless hours meeting directly with the Thousand Oaks City Council, working alongside then-Ventura County Supervisor Linda Parks.
The project didn't clear its last obstacle until 2010, when Thousand Oaks attached one more condition to its approval: the community itself would need to fund construction of a bridge inside the park.
"The last hurdle... was to raise the funds to build a bridge that was in the park."
Allison and a group of fellow residents donated the money personally. On April 12, 2011, the City of Thousand Oaks finally signed off on an agreement with the County of Ventura and the Santa Rosa Valley MAC, clearing the way for construction to start after roughly thirty years of asking.
The Tractor Party That Built It
Approval didn't mean a contractor showed up with heavy equipment. Neighbors handled that part too. Mark Burley, Joe Markiewicz, and David Boyle brought their own tractors to level the pad the park now sits on. Once the grading was done, Master Gardener Tom Wade and his wife Diane led a planting party to put in the landscaping. The park Santa Rosa Valley residents use today started as a literal group project, built by the people who now ride and walk through it.
What the Bridge Actually Leads To
Cross that bridge now and you're on a trail network that has grown well past what one bridge negotiation secured. From the equestrian parking area off Hill Canyon Road, which has enough room for full-size horse trailers, riders and hikers can pick up the Hill Canyon Trail, the Hawk Canyon Trail, the more demanding Western Plateau Trail, or the climb up to Snake Rock, a route shared by mountain bikers and equestrians on the same fire roads. The park also connects directly to the Conejo Canyons bridge, which gives Santa Rosa Valley residents a walk-in route into the Western Plateau trails on the Thousand Oaks side, maintained by the Conejo Open Space Foundation.
A few things about the terrain are worth knowing before you go:
- The canyon has multiple water crossings, since part of it functions as a filtration wetland tied to the area's wastewater treatment system, so trails can be damp even when the rest of the valley is dry.
- Spring brings blooming cactus and heavier bird activity, with hawks common enough that Hawk Canyon Trail earns its name honestly.
- Early morning and late afternoon are the reliable windows for spotting deer, and dogs are welcome on leash throughout.
On site, two equestrian riding areas with a training arena, a pair of horseshoe pits, and individual picnic tables with barbecues round out the built amenities. There's no playground, and that omission is deliberate. This was never meant to be a swings-and-slides family park. It was built for exactly what residents spent thirty years fighting to secure: horseback riding, hiking, and open space that stays open space.
That equestrian-first design is also why Stepping Stones Riding Program now runs lessons directly out of the park, offering riding experiences at accessible rates regardless of a rider's financial background. It's a use nobody would predict from a standard county parks brochure, and it only works because the site was purpose-built for horses from its first tractor pass.
Governance That Never Fully Handed Off
Most public parks eventually become a line item in a parks department budget, maintained by staff who had nothing to do with building them. Santa Rosa Valley Equestrian Park hasn't made that full transition, and that's part of what makes it different from a typical neighborhood amenity.
Ventura County did formalize the surrounding trail system in 2014, when the Board of Supervisors adopted the Santa Rosa Valley Trail Master Plan, officially recognizing a network of multi-use trails for pedestrians, bicyclists, and equestrians and later folding it into the County General Plan. That gave the trail system a legal backbone it didn't have before. But day-to-day stewardship still runs through the same channels that built the park in the first place. Santa Rosa Valley Trails Inc. continues to maintain the riding and hiking network, and the Rancho Santa Rosa Property Owners Association lists the organization as an active community resource rather than a historical footnote. The Santa Rosa Valley MAC that spent thirty years lobbying for the park is still meeting today, with sessions on the calendar as recently as September 17, 2026.
The tradition of neighbor-run events at the park has continued too. The "No Place Like Hope" picnic, created by resident Kimme Black, has become a recurring gathering there, the kind of event that only happens on ground residents still treat as theirs to program, not just visit.
Why This Matters If You Live Here
None of this history changes how the park feels on an ordinary Saturday. Horses still cross that bridge without their riders knowing it took a personal fundraising campaign to exist. Dogs still walk the shaded stretches of Hill Canyon Trail. Families still find the barbecue tables without knowing a Master Gardener and his wife planted the landscaping around them by hand.
But knowing the backstory changes what the place means. Santa Rosa Valley didn't inherit this park from a government agency that decided the area needed one. It negotiated for it across a city line, built the physical site with borrowed tractors, and has kept showing up to maintain it more than a decade after the ribbon-cutting. That's a different relationship to a piece of open space than most neighborhoods get, and it's worth remembering the next time you're loading a horse trailer at Hill Canyon Road or walking the Hawk Canyon Trail at dusk.
