Run north on the Tustin Branch Trail from the Newport Avenue side and you will eventually hit a dead stop at a street corner, with no marked crossing and no obvious continuation. Turn around, drive a few minutes north, and you will find another stretch of the same trail winding through a landscaped strip near Esplanade Avenue, seemingly unconnected to anything. Locals thread the two together on sidewalks without much thought. Newcomers assume the gap is an oversight, a project someone forgot to finish.
It isn't an oversight. It's a flood.
A Railroad, Not a Recreation Plan
The Tustin Branch Trail sits on a former Southern Pacific rail line that once hauled oranges out of the Tustin Packing Company to markets across the country. That freight service ran from 1905 until the corridor washed out at Santiago Creek in 1969, and the railroad never rebuilt across it. The tracks came up. The right-of-way sat idle for decades. When the county eventually converted it into a public trail, the creek crossing was still the same obstacle it had been for the trains, so the trail inherited the same break in the middle.
That is the whole explanation for the gap. It isn't a funding shortfall or a jurisdictional standoff. It's a water crossing that ended freight service more than fifty years ago and has shaped every plan for the corridor since.
What the County Actually Bought
Converting an abandoned railroad into a usable trail took longer than most people would guess. County records show it took fourteen years of effort by staff, the Board of Supervisors, and the public before Orange County finally took ownership of the right-of-way in December 2004, and even then it came in two separate segments rather than one continuous purchase. The construction work that followed went to Bullard Construction, Inc., under a contract worth $449,600 for what the county called the Tustin Branch Trail and Greenway project.
The corridor itself doesn't respect city lines any more than the old railroad did. Filed environmental documents describe the trail extending through a small section of the city of Tustin, the unincorporated area of North Tustin, Villa Park, and the city of Orange, following the original rail alignment toward Glassell Street. That cross-jurisdictional path is part of why the trail reads as a patchwork rather than a single planned amenity. It was never one agency's project to begin with.
Two Segments, Two Very Different Walks
The northern and southern halves of the trail don't just sit in different places. They feel like different trails entirely.
| North segment (Esplanade) | South segment (Newport Ave) | |
|---|---|---|
| Surface | Hard-packed clay and sand | Concrete sidepath |
| Character | Wide, landscaped strip through quiet residential streets | Sidepath running alongside a busy arterial |
| Amenities | One drinking fountain, no restroom | Public parking lot near Guin Foss Elementary on Vanderlip Avenue |
| What's nearby | Street parking on Esplanade Avenue, a single crossing at Dodge Avenue | Shopping centers, restaurants, banks, a gas station with a car wash, a flower shop, an ice cream parlor |
The north segment is the one that reads like a park. It's shaded, planted, and quiet enough that trail trackers list it as good for birding. The south segment does something different: it functions as a working sidepath that gets people from their front door to actual errands, past a run of small businesses that has grown up alongside it over the years, including nearby Tustin Heights Shopping Center on Irvine Boulevard, anchored by a Trader Joe's and a Smart & Final.
Bridging the Gap Yourself
The short gap between the two segments isn't marked as an official trail extension, but it isn't a mystery either. Regular users cross it on ordinary sidewalks along Warren Avenue, Holt Avenue, and Irvine Boulevard, picking the route back up at the Irvine Boulevard and Newport Avenue intersection where the southern concrete section begins. It's a few blocks on foot, not a wilderness crossing, and anyone who has walked the corridor more than once tends to know the detour without needing a map.
If you're starting fresh, the Columbus Tustin Park area is a reasonable entry point for the continuous stretch, and the Vanderlip Avenue lot by Guin Foss Elementary gives you a place to leave a car if you're planning to ride rather than walk from home. Trail trackers put the full out-and-back distance at a little over four miles, an easy grade with minimal elevation change, which is part of why it draws such a steady mix of runners, dog walkers, and parents pushing strollers.
Busy Despite the Break
None of this stops the trail from being, in the county's own words, the most used trail in North Tustin. That framing comes from an Orange County document written to justify further investment in the corridor, and it's worth sitting with for a second. A trail split by a fifty-year-old flood, stitched together with sidewalks, still functions as the default route for the neighborhood's daily foot traffic. The gap hasn't kept people off it. It's just made the trail something you learn rather than something you follow blindly.
Small evidence of the corridor's working history still shows up along the way. Near 17th Street and Esplanade Avenue, a marker known locally as the F.J. Paul plaque sits trailside, one of the few physical nods left to the freight line that used to run through here. Most people jog past it without a glance, which is probably how a working railroad wants to be remembered: quietly, underfoot, doing its job long after the last train ran.
The Same Season, More Reasons to Be Out Walking
Fall in North Tustin tends to pull people outside for reasons that have nothing to do with the trail directly. The North Tustin Fall Festival is set for Saturday, October 10, from 2 to 5 p.m. at the Tustin Hills Racquet and Pickleball Club, with the kind of afternoon programming that draws families out of their houses on a Saturday: food, music, a pumpkin station, face painting, a bounce house. It's a different corner of the neighborhood than the trail, but it's the same seasonal pattern. Cooler weather in October tends to put more people on foot across North Tustin generally, whether they're headed to a festival or just taking advantage of the first comfortable afternoon in months.
The trail and the festival aren't connected in any official sense. But they're both proof of the same thing: a neighborhood that keeps finding reasons to be outside, gap in the pavement or not.
