Which Lake Hollywood are you talking about?
Ask five people in Beachwood Canyon or Hollywood Dell where they walk their dog on a Saturday morning, and you will get five confident, contradictory answers. Some will tell you the loop around the reservoir is fine, dogs on leash, no problem. Others will tell you they got an earful from an LADWP guard the one time they tried it. Both of them are right, because they are talking about two different places that happen to share a name, sit a few hundred yards apart, and are governed by two completely different rulebooks.
That gap between the two Lake Hollywoods is not a rumor or a matter of interpretation. It is a jurisdictional line, and it decides whether your dog walk ends with a photo of the Hollywood Sign or a conversation with a utility employee.
The Reservoir Is Not a Park
The paved loop that circles Lake Hollywood, roughly 3.3 to 3.5 miles depending on which trail guide you check, is not city parkland. It belongs to the Los Angeles Department of Water and Power, and it exists because Mulholland Dam, built in 1924, still holds an active drinking water supply for the city. The reservoir has never functioned as a recreational lake. There is no swimming, no fishing, and, per LADWP's own posted reminder to neighbors, no dogs or other pets on the walkway path at all.
The reasoning LADWP gives is not aesthetic. It is a working water source, and pet waste near an active reservoir is treated as a health and safety issue rather than a courtesy issue. That is why the ban shows up as a formal notice from the utility itself rather than a suggestion from a parks department sign.
The loop has real infrastructure built around that purpose. Gate 2, on the northwest side off Lake Hollywood Drive, is where most walkers start, with a water fountain and a posted map of hours just past the entrance. On the southeast corner, the Weidlake Gate Trailhead connects to an unpaved stretch of Mulholland Highway that climbs toward the ridge where tourists gather for sign photos. Every entrance operates on the same schedule: gates unlock around 6:30 a.m. and lock again near sunset, with seasonal variation posted at each gate. Miss the window and you are, by more than one account from people who have done it, stuck inside until a guard notices.
None of that is dog-friendly infrastructure. It is water utility infrastructure that happens to double as one of the most photographed walking loops in the city.
Lake Hollywood Park Is a Different Address
A short drive or walk away, near the top of Beachwood Canyon, sits Lake Hollywood Park, and this is the smaller, separate green space that most people picture when they imagine the classic Hollywood Sign photo op. It is city parkland, not utility property, and it is explicitly dog-friendly. The park's own site is direct about the limits: dogs are welcome, but the park is not fenced and is not an off-leash dog park, and there is one small, fenced picnic area where even leashed dogs are asked to stay out. There are water fountains but no restrooms, and the same sunrise-to-sunset hours apply.
That is the entire distinction. One is a reservoir loop owned by a water utility where pets are banned outright. The other is a small hillside park a short distance away where pets are allowed under normal leash rules. They share the words "Lake Hollywood" in their names and almost nothing else.
Why Even the Apps Get This Wrong
If the confusion were just word of mouth, it would fade over time. It has not, because the platforms people use to plan a dog walk do not distinguish between the two places either. Yelp's listing for the reservoir carries a "Dogs allowed" tag, which directly contradicts the utility's own posted policy, and the site's own Q&A thread on that page shows someone asking in plain terms whether dogs are actually allowed, only to be told flatly by another user that no pets are allowed and that following the rule comes down to personal integrity. Trail guides tell a similarly split story: one AllTrails review of the reservoir loop notes approvingly that no dogs are allowed on the paved path, while a separate comment thread on a hiking guide site describes several different people walking dogs along that same loop on a single visit, rule or no rule. Meanwhile, a dog travel site lists Lake Hollywood Park correctly as a popular dog-friendly hike, with no mention that a nearly identically named reservoir loop nearby operates under an opposite rule.
That is the real finding here. This is not a case of a few confused tourists misreading a sign. The metadata itself, across Yelp, AllTrails, and general trail aggregators, is inconsistent at a structural level. A resident who has lived in the Hills for a decade and checks an app before a walk is just as likely to get a wrong answer as a first-time visitor, because the apps have never sorted out which Lake Hollywood they are describing.
What This Looks Like on the Ground
The practical result is a low-grade, recurring friction that longtime locals mention on neighborhood boards more than once a season. Someone brings a dog to the reservoir loop, gets stopped near Gate 2 or waved off by a guard doing rounds, and later posts about it, usually alongside someone else insisting they walk their own dog there every week without incident. Enforcement is not constant, which is part of why the confusion persists instead of resolving itself. A rule that is posted but only intermittently enforced reads, to a lot of people, like a suggestion rather than a boundary, even when the agency that owns the property has been explicit about it.
If you already live near the loop, the fix is simple once you know where the line is drawn. If your Saturday morning plan involves a dog, Lake Hollywood Park is the destination, not the reservoir. If it involves the full paved loop and a view across the water toward the dam, leave the dog at home and plan on that trip being just for you. The two are close enough that you could visit both in the same outing, but they are not interchangeable, and treating them as the same walk is exactly how the mix-up keeps happening.
For anyone new to the neighborhood, or hosting visitors who found "Lake Hollywood hike" on a map and assumed one set of rules applies everywhere nearby, this is worth explaining before you leave the house. It saves a conversation with a utility guard, and it saves your dog a walk that turns around five minutes in.
