Five different community calendars ran the same listing this spring. The Acorn, the Moorpark Acorn, the Simi Valley Acorn, all pointed readers to the same Saturday: March 21, 10 a.m. to 1 p.m., Oak Canyon Community Park, 5600 Hollytree Drive. "Feeling Good in Oak Park," the entry read, promising local wellness vendors and free guided sessions, hosted by the Rancho Simi Recreation and Park District. Even the Oak Park Community Garden's own event page said its volunteers planned to set up a table there, hand out seeds, and talk composting.
Search for that same event on the district's own website today and you get one line: the Oak Park Spring Wellness Expo has been cancelled. No explanation, no rescheduled date. Just a page that once described face painting and vendor booths, now stripped down to a cancellation notice.
The expo's cancellation is one update to Oak Park's community calendar. The parks, trails, and other places described below offer another view of everyday life here.
Oak Park is unincorporated. It has no city hall, no city council, no dedicated parks department that answers only to Oak Park voters. County supervisor Jeff Gorell's office and the Oak Park Municipal Advisory Council handle the advocacy side, meeting monthly at Oak Park High School to flag concerns up to the county. Nearly everything you'd call civic infrastructure, from streetlights to landscaping, runs through Community Service Area 4, and nearly everything recreational runs through the Rancho Simi Recreation and Park District, the same agency that also serves Simi Valley.
Oak Park's public amenities are managed through several agencies, while community events may involve additional organizers and partners. Parks, trails, and courts are ongoing amenities; a one-time event has its own schedule and may change. Check with the organizer for event details before making plans.
Here are a few of the public spaces residents can enjoy:
These parks and trails are part of Oak Park's everyday landscape. Oak Park's buildable land has been fully developed for years now, with the remaining open space owned outright by the recreation district rather than any private developer.
Some of what holds steady in Oak Park isn't a facility. It's a person or an institution that's been showing up long enough to become part of the rhythm.
The Oak Park Community Garden has been organizing plantings, plant sales, and school visits since 2004. This spring it hosted first and fifth graders from Oak Hills Elementary for lettuce tastings and lessons on pollination, and back in January 2025 it brought in an Athens Services sustainability specialist to talk commercial composting alongside what one regular half-jokingly calls the group's "celebrity composter." The garden has also been formally recognized by the Municipal Advisory Council and Supervisor Gorell's office, which is its own small signal that this is an institution the county treats as a fixture rather than a pop-up.
The Oak Park Library, tucked onto the Oak Park High School campus rather than standing as its own building, got a new branch manager last year. Mia Lopez was still in her first year running it as of this August, according to reporting in The Acorn, and the library keeps operating the way branch libraries do regardless of who's behind the desk: quietly, on schedule, without needing five calendar listings to confirm it's open.
And then there's Halloween. The Oak Park Halloween Carnival returns this year on Saturday, October 31, from 3 to 6 p.m., with carnival games, face painting, and the same candy-and-prizes format the district has run for years. The carnival is run internally by RSRPD staff; the wellness expo was a separate event.
Oak Park's civic life includes both ongoing public amenities and scheduled community events, each with its own place in the community.
For one-time events, check with RSRPD at (818) 865-9304 for details before making plans.
Oak Park earned its own ZIP code in 1999, splitting off from the one it used to share with Agoura Hills, a small bureaucratic marker of a community that had grown enough to stand on its own on paper even without becoming its own city. Almost thirty years later, its identity still runs less through borrowed civic institutions and more through the ground itself: the trail behind the library, the pond next to the community center, the courts at Deerhill, the garden. For one-time events, check the organizer's latest information before planning around them.
