Every few months, a screenshot circulates of a walking loop traced neatly around a body of water behind Mulholland Drive, captioned with some version of "found this hidden gem." The water is Stone Canyon Reservoir. The loop does not exist. What that satellite image actually shows is a fenced, active drinking-water facility owned by the Los Angeles Department of Water and Power, built in 1924 and still doing its job nearly a century later.
The confusion is understandable. From the road, the reservoir looks exactly like the kind of place a neighborhood would build a trail around. It sits at 847 feet in the Santa Monica Mountains, south of Mulholland Drive and west of North Beverly Glen Boulevard, and it supplies part of the Westside water subsystem that serves roughly 400,000 people across Pacific Palisades, the Santa Monica Mountains, and West Los Angeles. That scale is precisely why the gate stays locked. This is infrastructure, not parkland, and LADWP enforces the no-trespassing line strictly.
What most people are actually looking for, without knowing its name, sits a short walk away.
What You're Allowed to See
The Stone Canyon Overlook occupies the south side of Mulholland Drive on the Mulholland Scenic Parkway, managed by the Mountains Recreation and Conservation Authority. It is a short, fragrant, ADA-accessible path, not a loop around the water but a fixed vantage point looking down at it. On a clear day the view extends past the reservoir to the Palos Verdes Peninsula and Catalina Island.
The overlook carries a dedication to Anton Calleia, who served on the Santa Monica Mountains Conservancy from 1980 to 1993 under an appointment from Los Angeles Mayor Tom Bradley. It is a small, specific piece of civic memory attached to a small, specific piece of public land, which is the pattern worth noticing before we get to the rest of the neighborhood.
Why the Fence Isn't Coming Down Soon
There is a real proposal on file to eventually route hiking trails through part of the site, contingent on rebuilding the smaller Upper Stone Canyon Reservoir as underground storage instead of an open surface pool. That plan has been under discussion for years. It remains unbuilt, and nothing in the current timeline suggests the lower reservoir, the one visible from the overlook, is part of any near-term access plan at all. If you are budgeting your week around a future reservoir loop, budget around something else.
The Actual Trailheads
The neighborhood's real walking options are a short list of named trailheads rather than the reservoir circuit people assume is out there:
- Westridge-Canyonback Wilderness Park, a Santa Monica Mountains parcel accessible from the Brentwood side of the ridge
- Mandeville Canyon Fire Road, a maintained fire access route that climbs into the mountains above Bel Air
- Caballero Canyon Trail, reached from the Encino side and connecting into the broader Santa Monica Mountains trail network
- Getty View Trailhead, which does double duty as a walking approach to the Getty Center on the days the freeway ramp below it is not cooperating
That last one matters more this year than most, because the ramp in question has not been cooperating for a while.
The Ramp That Keeps Closing
The Sepulveda Pass has been under active construction along Interstate 405 for over a year, with overnight lane reductions and ramp closures that come with little public notice beyond Caltrans' own bulletins. In March 2026, crews closed the northbound off-ramp to Getty Center Drive overnight while reducing both directions to fewer lanes through the pass, work that has continued on a rolling schedule since. Speed limits through the corridor have been reduced since late May 2026, and the project is not expected to wrap before winter 2027, with plant establishment continuing into 2028.
None of that is announced far in advance, which is why residents have settled on the same two workarounds rather than waiting for a map update:
| Direction | Workaround |
|---|---|
| Northbound | Stay on Sepulveda Boulevard, rejoin the freeway at Skirball Center Drive |
| Southbound | Cut over to Church Lane, reach the Sunset Boulevard on-ramp |
On the days neither workaround feels worth it, the Getty View Trailhead gets you to the museum on foot, which is either a fallback or the better option depending on how much you enjoy Sepulveda Pass traffic. The Getty Center itself remains free with a timed-entry reservation, closed only on New Year's Day, Independence Day, Thanksgiving, and Christmas.
What Actually Fills the Calendar
If the reservoir and the ramp are the two landmarks that look more available than they are, the neighborhood's real texture runs through smaller, more specific institutions that have simply kept showing up.
Hotel Bel-Air brings back its mid-September grilling event on the hotel's front lawn and gardens most years, drawing chefs like Evan Funke and Jackson Kalb alongside a lineup of wine and spirits from around the city. It is not a public festival. It is a hotel doing the same well-executed thing on the same patch of lawn, year after year, which is a different kind of consistency than a trail system that may or may not get built.
The Bel-Air Garden Club has been doing something similar since 1931, when it formed around members developing "an active interest in gardening with its multiplicity of opportunities to create beauty and happiness." Nearly a century later it is still organized around the same idea, pursuing garden-adjacent interests in architecture, art, landscaping, and interior design, and still building its community through the same kind of small, recurring gathering rather than any single flagship event.
That is the actual shape of Bel Air's calendar. Not a sprawling public trail system or a marquee annual festival, but a short list of specific, well-run, recurring things: an overlook with a dedication plaque, a hotel lawn in September, a garden club old enough to have outlasted several generations of the plants it was founded to discuss.
The next time a hiking app tells you there's a loop around Stone Canyon Reservoir, you will know exactly which part of that claim is true. The overlook is real, the view is real, and the water stays exactly where the fence says it does.
If you are curious how a neighborhood like this actually works, from its access points to its architecture, Josh Flagg has spent a career reading Bel Air at that level of detail.
