Pull into the trailhead at Hallmark and Lake Road on a Saturday morning and you will see it before you hear it: cars already lining both sides of the street by eight, dogs pulling toward the dirt road that drops into the canyon, someone tightening a shoelace against a bumper. Waterdog Lake has drawn that crowd for years. What happens after the hike is the part that changed.
For a long time, the after was simple. You finished the loop, maybe swung by Carlmont Village Shopping Center for a bagel or a bag of hardware, and if you wanted an actual sit-down dinner that felt like an occasion, you got back in the car and drove to San Mateo or Burlingame. Belmont had the trail. It didn't have anywhere to end the day.
That gap closed inside the last twelve months, and the timing lines up with something else on the calendar: the Belmont Water Dog Run, the community race built entirely around this same trail system, returns on September 26. It's worth looking at both halves of that story together, because the run is the clearest evidence of how much residents already organize their lives around Waterdog Lake, and the storefronts that opened around it this year are the first sign that the rest of the neighborhood is catching up.
A Trail Network That Outgrew Its Own Trailheads
Waterdog Lake Open Space isn't a single path. Combined with the adjoining John S. Brooks Memorial Open Space and Hidden Canyon Park, the network covers more than 260 acres of hillside west of El Camino Real, threaded with trails that range from flat lakeside walking to steep single-track. Three separate entry points feed into it: Hallmark and Lake Road, 2400 Lyall Way near Lake Road, and 2642 Carlmont Drive, which means residents on different sides of town can reach the same network without driving across it.
The lake itself has an origin story most hikers walk past without knowing. William Ralston, the banker who built Ralston Hall Mansion, originally had it dammed to collect spring water for his estate. The Sisters of Notre Dame de Namur later held the land and leased it to the City of Belmont in 1965, and John S. Brooks donated another 51 acres in 1978, land that now carries his name on the trail map.
The most-used route through it, the loop that links the John Brooks Trail with the trail around the lake itself, runs about 2.9 miles with roughly 456 feet of elevation gain, and it ends at a stretch of water where leashed dogs are welcome to cool off, which is part of why the route shows up on so many Saturday routines. Dogs need to stay leashed for the rest of the network. If you want off-leash time, Cipriani Dog Park is the designated spot for that, not the open space itself.
None of this happened by accident or by neglect, either. In March 2026, the Trail Center worked directly with the City of Belmont on active restoration of the Elevator and Rambler trails inside Hidden Canyon Park, repairing tread and clearing brush on sections that had gone rough. A volunteer group called the Waterdog Trailkeepers keeps the network usable between the city's own maintenance cycles. The trail isn't just old and beloved. It's actively maintained, this year, by name.
The Run That Grew Faster Than Anyone Expected
The Belmont Water Dog Run is what happens when a community stops just using a trail and starts organizing around it. The race starts and finishes at Twin Pines Park and includes a 5k, a 10k, a one-mile kids' run, and a Fido mile for dogs and their owners, timed for September 26 this year.
What's notable isn't just that the race exists. It's how fast it grew. The event's own numbers show registration starting under 600 and climbing to nearly 1,200 in a matter of a few years, a pace that outstrips almost anything else on the Belmont community calendar. The Rotary Club of Belmont and Redwood Shores runs the pancake breakfast that goes with it, and more than a dozen students from Carlmont High School handle the event's design, marketing, and race-day logistics every year as part of the planning. The proceeds haven't stayed abstract, either. Grants from the race have gone to BRYSA softball scholarships, AYSO soccer scholarships, and teen wellness programs, meaning the run funds the same kind of youth activity that fills the trail on any given weekend.
That growth curve says something specific about Belmont: residents don't treat Waterdog Lake as scenery. They treat it as infrastructure worth building a civic calendar around.
What Actually Landed in Carlmont Village This Year
Carlmont Village Shopping Center, at the corner of Ralston Avenue and Alameda de las Pulgas, has always been Belmont's answer to a downtown even though it was never built as one. For years its identity ran through practical anchors: Lunardi's Markets for groceries, Hassett Ace Hardware for everything else, Village Host Pizza & Grill for a fast dinner, Doc's Bagels for the morning stop. Reliable, and entirely about errands.
Three additions in the last year have started to change what the center is for.
| Business | Opened | What changed |
|---|---|---|
| Truffle Poké Bar | March 2026 | Fourth Bay Area location from founder Rafic Haddad, at 1073 Alameda de las Pulgas, with signature bowls like the Salmon Lover and Rafi's Pick |
| Lalo Valentino Salon | January 2026 | Owner Bobbie de la Fuente, nearly two decades in the industry and seven years co-owning a Redwood City salon, opened at 1075 Alameda de las Pulgas |
| Amara | 2025 | A sit-down restaurant from the Saffron Restaurant Group, whose other Peninsula locations carry Michelin recognition, filling a former tavern space in the center |
None of these three replace what Carlmont Village already did well. Lunardi's is still the grocery run, Ace Hardware is still the hardware run. What changed is that the center now has a reason to stay past the errand: a full sit-down dinner at Amara, a fast but genuinely good bowl at Truffle Poké Bar, a haircut from someone with two decades in the chair rather than a walk-in chain. For a shopping center that spent decades being useful without being a destination, that's a real shift, even if it's a quiet one.
Same Saturday, Rewritten
Run the morning back with all of this in place. Eight a.m. at the Hallmark and Lake Road trailhead, the loop around the lake, the dog cooling off at the end of it. From there it's a short drive or walk to Carlmont Village, but instead of grabbing a bagel and heading home, there's an actual reason to linger: errands at Lunardi's, a stop at the poke bar for lunch, maybe a haircut booked for later in the week. On Sundays, the Belmont Certified Farmers' Market runs year-round from 9 a.m. to 1 p.m. at 1201 El Camino Real, another fixed point in the weekly rhythm that doesn't require leaving town.
And in the evening, instead of the drive to San Mateo or Burlingame that used to be the default for anything beyond takeout, dinner is three minutes away at Amara.
That's the part of this story that doesn't show up if you look at the trail and the shopping center separately. Waterdog Lake has been the reason people move to this part of Belmont for years, the anchor that shapes weekend plans and now fills a race with nearly 1,200 runners every fall. Carlmont Village was the practical center that supported daily life without ever asking anyone to stay. This year, for the first time, the two halves of a Belmont Saturday actually connect. The morning still belongs to the trail. The evening finally belongs to the neighborhood too.
If you've watched Belmont change from the inside this year, you already know how fast a shopping center can go from a stopover to a destination. If you're weighing what any of this means for a home search on the Peninsula, or just want a longtime local's read on how a neighborhood like this holds its value over time, Carmen Miranda has spent decades watching these details add up.
