Drive north on Beverly Glen toward Mulholland on a clear afternoon and the hillside opens up: a flat sheet of water ringed by eucalyptus and chaparral, sitting below the road like something built for a Sunday walk. Guests ask about it constantly. Residents who have lived here for years still slow down for it. It looks like a park. It is not one.
Stone Canyon Reservoir belongs to the Los Angeles Department of Water and Power, and the agency has been direct with the neighborhood about what happens if you try to walk in: the property is fenced, gated, and enforced, not simply posted. The two connected basins, Stone Canyon and the smaller Upper Stone Canyon, sit inside a working utility site that supplies drinking water to roughly 400,000 people across the Westside, including Pacific Palisades and West Los Angeles. The restriction dates back further than most people assume. The canyon was the origin point of the 1961 Bel Air Fire, which burned 464 homes before it was brought under control, and the site has stayed closed to the public in the decades since.
There is a plan on file to eventually change that. LADWP has proposed replacing the aging Upper Stone Canyon Reservoir with underground storage, covering the structure with soil and vegetation, and running a hiking trail across the top of it. That proposal has been under discussion for years and remains unbuilt. If someone tells you Bel Air is getting a reservoir trail soon, they are describing a filing, not a completion date.
What You Can Actually Walk
The good news is that the neighborhood's real trail list is shorter, better marked, and entirely open right now. None of it touches the reservoir, and none of it requires guessing whether you are trespassing.
- Stone Canyon Overlook, on the south side of Mulholland Drive, is managed by the Mountains Recreation and Conservation Authority. The path is short and ADA accessible, and it delivers the view people actually want: the reservoir from a distance, with the Palos Verdes Peninsula and Catalina Island visible on a clear day.
- Getty View Trailhead works as both a hike and a shortcut, doubling as a way to approach the museum on foot when the freeway ramp below it is uncooperative, which this year is more often than usual.
- Mandeville Canyon Fire Road and Caballero Canyon Trail sit slightly west, longer routes for anyone treating the walk as exercise rather than a scenic stop.
- Westridge-Canyonback Wilderness Park rounds out the list, a bigger property that connects into the broader Santa Monica Mountains trail network rather than dead-ending at a fence line.
Two Gates, One Rule
The reservoir is not the only landmark in Bel Air that reads as more restricted than it is. The neighborhood's two entrances work the same way in reverse. The East Gate on Bel Air Road carries the blue neon sign most people photograph without knowing what they are looking at. The West Gate, off Bellagio Road, is the more theatrical of the two, with arches dramatic enough that first-time visitors sometimes mistake it for a studio lot entrance. Both have a guardhouse. Both sit on roads that are open to the public. The imposing gate and the working reservoir send the same visual signal, and it is wrong in the same direction each time: the more fortified something in Bel Air looks, the less it tells you about who is actually allowed to use it.
The Off-Ramp That's Rewriting the Walk
Getty View Trailhead matters more this year than it has in recent memory, because the road it substitutes for has become unreliable on its own schedule. The Getty Center Drive off-ramp is the front door to the museum and, functionally, to the Sepulveda corridor running along Bel Air's eastern border. Since the summer of 2025, that door has been opening and closing according to a construction timeline tied to the I-405 Sepulveda Pass Pavement Rehabilitation Project, a $143.7 million Caltrans effort to replace and restripe roughly 92 lane miles of freeway between Van Nuys and Westwood.
The project will not fully wrap until winter 2027, with plant establishment continuing into 2028, and speed limits along the corridor have been reduced to 55 miles per hour since late May 2026 while paving continues.
During earlier phases of the work, Caltrans pointed drivers toward two specific workarounds, and residents have kept using both since:
Northbound: stay on Sepulveda Boulevard and rejoin the freeway at Skirball Center Drive. Southbound: cut over to Church Lane to reach the Sunset Boulevard on-ramp.
Neither route is signed as a detour. Both only make sense once you have been stuck at the closed ramp once and gone looking for an alternative.
The Smaller, Realer Map
The postcard version of Bel Air is a reservoir you can see from the road and a pair of gates guarding streets full of hidden estates. The version residents actually use is narrower and more specific: five named trailheads, none of which touch the water everyone stops to look at; two gates that are more decorative than functional; and a freeway project with a firm end date that is still more than a year away. Together, these details offer a practical picture of Bel Air’s trails, gates, and road access.
