Ruffin Canyon Finally Got Its Trail. Here's Why That Almost Never Happens in Clairemont.

"It's nice we can just come out our back door and be here," said Ron Shephard, a longtime hiker in the Escala community, describing his first walk on the newly reopened Ruffin Canyon Trail. Escala sits at one end of the pedestrian tunnel that now connects the canyon to Mission Valley, and Shephard told CBS 8 the moment felt overdue.

He undercounted it. A 2008 city document tied to the Friars Road pedestrian tunnel first floated the idea of a continuous trail through the canyon. The tunnel opened in 2009. The trail itself didn't follow for another seventeen years.

Ruffin Canyon itself sits just outside Clairemont, threading the border between Serra Mesa and Mission Valley. But the lesson it offers travels well, because whether a canyon trail in this part of San Diego gets rebuilt or left to erode has less to do with which city department technically owns the parcel and more to do with whether a volunteer group spent years organizing around that exact stretch of dirt. Ruffin Canyon had one. A Clairemont canyon a short drive away, right now, does not.

A Trail Seventeen Years in the Waiting

On Friday, April 17, 2026, the City of San Diego cut the ribbon on a rebuilt trail through Ruffin Canyon, connecting Serra Mesa to Mission Valley for the first time with a route designed for walkers, hikers and cyclists. The project added three new wooden footbridges, rerouted sections of trail along the canyon walls, and restored wetland areas that had been degraded for years. Access from the Serra Mesa side runs through two points: the south end of Ruffin Road near Taft Middle School, which offers the most varied terrain and habitat, or the western end of Shawn Avenue, an easier walk. From Mission Valley, hikers enter through the tunnel on Friars Road across from Costco at Fenton Marketplace, at the base of Escala. There's no signage once you're through the tunnel, so the unofficial directions are to walk uphill toward the Escala clubhouse until the trail picks up.

Peter Hulbert, director of the San Diego Mountain Biking Association, spoke at the ceremony about what the rebuilt access actually restores. "The way we have come to love and know our natural spaces, the plants and animals that inhabit them, is because of a trail," he said. "It gets us in there. It allows us to participate."

Unlike some of San Diego's urban canyons, which have been overtaken by non-native growth, Ruffin's restored sections are dominated by native species: monkey flower, lemonade berry, California sage, and broom baccharis. That detail matters more than it sounds, because it's a direct measure of how much upkeep the canyon has actually received compared to its neighbors.

Who Actually Built It

The seventeen-year gap wasn't a funding problem waiting for money to appear. It was an organizing problem that eventually found the right combination of people. Kevin Johnston, a nearby resident and volunteer with Friends of Ruffin Canyon, has been pushing for the trail connection for almost two decades. Before that, he spent 14 years on the board of the nonprofit San Diego Canyonlands and belonged to Friends of Normal Heights Canyons, so he arrived at Ruffin Canyon already knowing how these projects move through the city.

The path from idea to ribbon cutting ran through a specific sequence: the San Diego River Conservancy published a feasibility report on possible routes in 2010, a California Environmental Quality Act draft analysis followed in 2013, the project stalled again until the Serra Mesa Planning Group approved using Developer Impact Fees toward permitting costs in 2015, and the initiative then sat with the City of San Diego for another decade. Financing eventually came together through a combination of state grants and taxpayer money set aside for park improvements. The Escala Homeowners Association, which initially resisted the project, later became one of its supporters and helped build community backing for it. Councilmember Raul Campillo attended the April ribbon cutting alongside Johnston, HOA representative Cindy McIntyre, and the partner organizations that share credit for finishing it: the City of San Diego, the San Diego Mountain Biking Association, Friends of Ruffin Canyon, and San Diego Canyonlands.

That's four organizations, one council office, and one HOA, coordinated over roughly two decades, to fix a single canyon trail. It's worth holding that number next to what's happening in Keller Canyon right now.

A Clairemont Canyon With No Comparable Group

Marie Hartwell has hiked Clairemont's Keller Canyon Trail regularly for years, the route that extends into the Marian Trail toward Marian Bear Memorial Park. She told CBS 8 it used to be her favorite trail. Now she describes it as neglected: Mexican fan palm, an invasive species, has spread into the streambed and disrupted the ecosystem downstream. Graffiti, trash, dead trees, and overgrown brush line sections of the path. Hartwell called it a fire hazard waiting to happen, on a trail used by hikers, dog walkers, cyclists, and e-bike riders. She's filed three or four maintenance requests through the city's Get It Done app over recent years. None have resulted in visible work.

The frustrating part is that Keller Canyon hasn't been entirely ignored. Between 2022 and 2023, the San Diego Mountain Biking Association partnered with the city on a bridge replacement in Keller Canyon, the finger canyon that feeds into Marian Bear from Clairemont Mesa. That was capital infrastructure work, funded through the same kind of partnership model that eventually rebuilt Ruffin. But brush clearing, invasive plant removal, and dead tree removal fall into a different maintenance bucket, one that runs through routine service requests rather than organized capital projects. Nobody has built a Friends of Keller Canyon to push that second bucket forward, so those requests move at the pace of whatever staff bandwidth the Parks and Recreation department has that month.

Two maintenance tracks run through the same canyon system. One gets funded when a nonprofit, a council office, and an HOA spend years coordinating around a specific project. The other depends on whether enough individual residents keep filing the same request until someone acts on it. Ruffin Canyon shows what the first track produces. Keller Canyon shows what happens when only the second one is running.

What's Actually Walkable Right Now

For residents deciding where to spend a Saturday morning, the practical differences between these trails matter as much as the history behind them.

• Ruffin Canyon Trail: 3.4 miles out and back, rated an easy route by AllTrails with an average completion time of about 90 minutes. Dogs are welcome and may be off leash in parts of the trail. Open year-round.
• Tecolote Canyon Natural Park: roughly 6.5 miles of multi-use trail for walking, jogging, and mountain biking, anchored by the Nature Center at 5180 Tecolote Road. Dogs must stay leashed throughout. The Nature Center's visitor hours run Tuesday through Saturday, 10 a.m. to 4 p.m., closed Sunday and Monday. Over the summer the center ran family-oriented programming through partnerships like Family Library Day with North Clairemont Library, along with evening Nature Nights talks, including one on snake ecology led by an SDSU biology professor.
• Keller Canyon Trail into Marian Bear Memorial Park: still open and still used daily by hikers, cyclists, and dog walkers, but sections carry the overgrowth and invasive palm growth Hartwell has flagged.

Tecolote Canyon and Keller Canyon both sit inside what local trail advocates call the Tri-Canyons area, a connected system spanning Tecolote Canyon, Rose Canyon, and Marian Bear Memorial Park that the San Diego Mountain Biking Association manages in partnership with the city, the county, the Clairemont Town Council, and the volunteer group Bike Clairemont. Ruffin Canyon is a separate system entirely, on the other side of Clairemont, which is part of why its fix didn't automatically extend to the trails still waiting nearby. The Tri-Canyons partnership model has produced real work of its own, including a Tecolote Creek crossing completed in fall 2023 and multiple bridge and erosion-control projects along the Tecolote Golf Course frontage.

Tecolote Canyon itself has been public land since the City of San Diego acquired it and dedicated it as a natural park on April 1, 1978, following use by the Kumeyaay and later farming and cattle grazing that continued into the 1950s. It divides Clairemont from Linda Vista on its southern half and splits west and east Clairemont on its northern half, which is part of why so many different neighborhood groups have a stake in how it's maintained.

None of this means Keller Canyon is beyond fixing. It means the fix, historically, has come from the same playbook that took Ruffin Canyon from a 2008 planning document to an April 2026 ribbon cutting: a named group, a council office willing to attend the ceremony, and years of showing up.
