Tecolote Canyon Isn't Closed. It's Just Rearranged.

Ask anyone who hasn't walked Tecolote Canyon since last year and they'll tell you it's shut down for construction. Ask someone who parked on Gardena Street last month and did the hillside loop instead, and they'll tell you something different: the canyon is quieter than they've ever seen it, and most of their neighbors don't know it.
Both things are true. That's the part worth understanding before you write off a trail system that runs through the heart of Clairemont.
The City of San Diego is in the middle of a multi-year project to rehabilitate and replace 4.7 miles of trunk sewer pipe running through the canyon floor, work that began in late 2024 and is expected to run two to three years total. The lines being replaced were installed in the 1950s and have never been touched since, which is the kind of detail that makes a sewer project sound less like bureaucracy and more like overdue maintenance on infrastructure older than most of the houses above it.
The city's project page breaks the work into phases, and the phase you're standing in determines what you'll find:
That's a specific, dated closure, not a vague "under construction" sign. If your usual route runs through that Mount Acadia to Balboa stretch, you're out of luck for a while. If it doesn't, you may not have noticed anything changed at all.
Here's where the misperception gets interesting. Reviewers checking trail conditions this spring kept noting the same thing: the main canyon trail from the visitor center was gated, but the Gardena Street entrance and the hillside loop above it were wide open, lightly used, and easy to find parking for. One hiker who did the loop in May put it simply after finding it empty on a Sunday: "Guessing people don't realize the hillside loop is still open."
That's the mechanism at work here. A closure notice on the main trailhead reads to most people as "the canyon is closed," so they stop going, and the alternate entrances quietly become the least crowded corners of a park that sits inside a dense residential neighborhood. The North Clairemont Community Park loop on the canyon's north end, a roughly 3.3-mile easy walk connecting to the Tecolote Canyon Stream, hasn't been affected by the sewer work at all. Neither has the short Battle Trail loop near Tecolote Community Park on the south end, an easy 1.6-mile stretch with only 42 feet of elevation change. If your mental map of the canyon is "closed," it's worth redrawing it around what's actually open rather than what used to be the default route.
The Tecolote Canyon Golf Course, which shares canyon land with the trail system, has had a rougher run. It was reduced to nine holes in August 2025 to accommodate construction crews, then closed entirely as of February 2026, with only the driving range still operating. The timing lines up with more than just sewer work. The city's lease with longtime operator American Golf Corporation had ended, and San Diego is now rebidding the contract while finishing the trunk sewer replacement underneath the fairways.
The revenue numbers explain some of the anxiety around what happens next. In the fiscal year cited in city audit data, Tecolote Canyon's course returned a quarter of its lease revenue to the city, about $735,293, while total lease revenue for the site came in just under $3 million. Compare that to Fairbanks Ranch Country Club, which generated $16.7 million in the same period despite paying a smaller percentage back to the city. That gap is part of why some community members worry the course could sit dormant rather than reopen on schedule. As of the most recent reporting in February 2026, the city said reopening was tied to selecting a new operator and finishing construction, targeted for that summer. If you golf here, that timeline is worth checking directly with the city before you plan around it.
For trail purposes, the practical takeaway is narrower: every path that runs through the golf course footprint is closed until the sewer work and the lease question both resolve, and the city has said a five-year vegetation restoration effort will follow once construction wraps.
While the trail network sorts itself into open and closed segments, the Tecolote Canyon Nature Center at 5180 Tecolote Road has kept running on its own schedule. It's open Tuesday through Saturday, 10 a.m. to 4 p.m., with the garden, patio, and outdoor restrooms accessible every day of the week. Parking is free, and the native plant garden outside gives a decent preview of what the canyon looks like once you're past the trailhead.
This year the center has hosted family programming like Nature Nights and a hands-on event called Canyon Connections, the kind of low-key, no-cost draw that makes the center worth building a Saturday morning around even if you have no interest in the trail closures happening a few hundred yards away. The nonprofit Friends of Tecolote Canyon also partners with groups like the San Diego Bird Alliance on periodic birding walks through the park, no experience or gear required beyond a willingness to stand still for a while.
If you do walk the open stretches near Balboa Avenue, you'll eventually run into the pedestrian tunnel that carries the trail underneath the road. Locals treat it less like an underpass and more like a rotating art installation, since the graffiti covering its walls changes with whoever's been through most recently. It's also become something of an acoustic curiosity among hikers who've tested it out loud.
The canyon's longer history runs back further than most people walking it realize. The city's own account notes that Kumeyaay Indians used the canyon for food and shelter long before it had a name on any map, and that Tecolote itself means owl, after the small raptor still seen there today. A settler named Judge Hyde built a home and began farming the canyon floor in 1872, and cattle continued grazing there as late as 1953, sometimes wandering into the backyards of homes along the canyon rim before ranchers rounded them back up. The city acquired the land and formally dedicated it as Tecolote Canyon Natural Park on April 1, 1978, the same year its first Citizens' Advisory Committee was sworn in. That's a century of working land compressed into a canyon most residents drive past without a second thought.
There's no permit or entrance fee required anywhere in the park, and dogs are welcome as long as they're leashed. Rattlesnakes, poison oak, and the occasional mountain lion sighting are all real enough that the city posts standing cautions, so sturdy shoes and some attention to where you're stepping go a long way, especially near the creek crossings that turn slick and occasionally swampy after rain, particularly at the southern end of the Balboa tunnel.
None of that is new information if you've hiked here for years. What's changed is which parts of the canyon reward that knowledge right now. The construction has, in its own inconvenient way, sorted the park into a busy, gated middle section and a set of quieter edges that most people have stopped checking.
If you've lived in Clairemont long enough to remember the canyon before any of this started, or you're new enough that you're still figuring out which entrance is yours, Kathleen Westwood has spent decades getting to know the small details that make San Diego's coastal neighborhoods worth staying in, not just the market data that shows up in a search.
