Peri Park and the Canyon Trail Are Both Closed. That's Not a Coincidence.

Peri Park and the Canyon Trail Are Both Closed. That's Not a Coincidence.

  • September 24, 2026

Two of the places Fairfax residents rely on most this time of year are partly off limits right now, and they went dark for the same underlying reason. Peri Park's shaded playground has been closed since late July. Cascade Fire Road, the main access point into Cascade Canyon Preserve, is blocked to the public on weekdays through the end of October. Neither closure is about a lack of town attention. Both are about a town that would rather wait than rush.

What actually happened at Peri Park

The playground closed on July 24 after Public Works crews found a significant flea infestation, traced to raccoons denning near the play structures. Fairfax bans pesticide use on town property, so the fix couldn't be a quick spray. Crews tarped and steam-treated the sand instead, using heat rather than chemicals, and the town initially expected the park back open around August 7, roughly two weeks out.

That date came and went. While the playground sat closed, the town brought in two independent certified arborists to look at the mature oaks that shade the park, and both flagged safety concerns serious enough to warrant removal. One tree, closer to Park Road, has a documented history of large-limb failure that has already damaged play equipment and parked cars, plus signs of a wood-boring beetle infestation. The other, nearer the creek, hasn't been touched by beetles yet, but the town concluded the risk of keeping either tree standing over an active play area outweighed the alternatives, including fencing off the canopy or relocating equipment.

As the town put it in its own update on the closure:

"We recognize that these mature oaks are beloved features of Peri Park and that their loss will be deeply felt. The Town is committed to evaluating replacement options that can restore shade and beauty to the park while providing a safer environment for families."

As of the town's September 15 newsletter, Peri Park still doesn't have a firm reopening date. What started as a two-week pest problem is now, nearly two months later, a tree removal and replanting project with no scheduled finish line.

Why the canyon trail is closed on a completely different clock

A few miles up Bolinas Road, Marin County Parks started work in early August on two new bridges across San Anselmo Creek inside Cascade Canyon Preserve, plus a replacement bridge over Carey Camp Creek. The goal isn't convenience. It's protecting steelhead trout and foothill yellow-legged frog habitat from the erosion caused by hikers, cyclists, and horses fording the creek at four low-water crossings, especially during high flows in the rainy season.

Because of that, the project runs on a habitat-conscious schedule rather than a fast one. Cascade Fire Road is closed to the public Monday through Friday, 8 a.m. to 4 p.m., from August 3 through the end of October, with construction vehicles, staged rock and lumber, and biological monitors on site throughout. But the closure is narrower than it sounds. Canyon Trail, Carey Camp Trail, Cascade Falls Trail, and Middle Fire Road all remain open the entire time, and Cascade Fire Road itself reopens before 8 a.m., after 4 p.m., and all weekend. If your usual loop depends specifically on a weekday midday pass through Cascade Fire Road, you'll need a workaround until November. Almost every other route into the preserve still works.

The pattern underneath both closures

Neither closure is a story about neglect. Both are stories about a town whose default setting, when a beloved outdoor space collides with a safety or habitat risk, is to slow down rather than push through. The pesticide ordinance that forced a heat treatment instead of a quick chemical fix at Peri Park is the same civic instinct that has Marin County Parks scheduling bridge work around fish spawning cycles rather than around a construction deadline. Fairfax protects the things that make it Fairfax, even when that protection costs residents a favorite shaded playground or a familiar fire road for a season.

That's worth knowing if you're the kind of resident who plans weekends around Peri Park's redwood cover or a loop through the canyon. The delays aren't bureaucratic drift. They're the tradeoff for a town that won't cut corners on an oak assessment or a creek crossing just to hit a self-imposed reopening date.

What hasn't slowed down at all

None of this has touched downtown's fall calendar, which is worth noticing on its own. The Fairfax Theatre Company is in the middle of its 19th annual production at the Fairfax Pavilion, a run of Oscar Wilde's "The Importance of Being Earnest," directed by Sam M. Parry. Performances are pay-what-you-will, spread across three weekends: September 11 through 13, September 18 through 20, and the final shows on September 26 and 27.

The following Friday brings the 7th annual Fairfax Art Walk, running from 5 to 9 p.m. on September 25, with downtown shops hosting local artists, live music, and the scavenger hunt that's become a fixture of the evening. The town's fall and winter recreation newsletter also lists the return of the Craft Faire as part of the season's lineup, alongside the usual run of classes through Fairfax Recreation.

None of this needed a park or a fire road to happen. Downtown, the Pavilion, and the sidewalks along Broadway carry Fairfax's public life just fine on their own, which says something about how the town's calendar is built. It doesn't lean on any single space so heavily that a closure or two throws off the whole season.

What to actually plan around this fall

  • Peri Park: Closed with no confirmed reopening date as of the town's September 15 update. Worth checking the town's site again before you head over.
  • Cascade Fire Road: Closed weekdays, 8 a.m. to 4 p.m., through the end of October. Weekends and early mornings are open, as are Canyon Trail, Carey Camp Trail, Cascade Falls Trail, and Middle Fire Road.
  • The Importance of Being Earnest: Final weekend at the Fairfax Pavilion, September 26 and 27.
  • Fairfax Art Walk: Friday, September 25, 5 to 9 p.m., downtown.
  • Craft Faire: On the fall calendar per the town's recreation newsletter, with details to follow.

If you're weighing a hike or a park visit against a construction sign, the honest read is that both closures are close to their end, one on a fixed October date and one on no date at all yet. Either way, the rest of the town isn't waiting on either of them to figure out what to do this weekend.


Fairfax has always been the kind of town that would rather get something right than get it open fast, and that instinct shows up as much in a town council decision as it does in the pace of a downtown storefront turning over.
