A woman pulls into the gravel lot at 33rd and Bell on a Saturday morning, gym bag over one shoulder, ready to run the hill the way she has for years. The attendant checks a tablet, not a clipboard, and asks for her reservation number. She doesn't have one. She has to leave, drive home, book a slot online, and come back within the hour if one's open. The dune is still sand. The rules around it are the part that changed.
Sand Dune Park looks like the kind of place that runs on nothing more than gravity and good weather. A hundred feet of loose sand rising off a three-acre lot in north Manhattan Beach, with 208 concrete steps running alongside it for anyone who wants an alternative to postholing straight up the slope. What actually governs who gets to use it, and when, is a reservation system with time slots, a capacity cap, and a non-refundable processing fee. That system exists because the city spent the better part of a decade negotiating its way out of a fight that nearly closed the dune for good.
The System Everyone Bumps Into
Anyone 13 or older needs a reservation to use the dune itself. Slots run one hour, cap out at 20 people, and can be booked online starting six days out, or same day up to the minute before the slot begins. The online booking system charges a 5.65 percent convenience fee that doesn't come back if you no-show. Monthly membership passes exist for people who'd rather skip the online booking altogether. Pass holders and adults 55 and older can walk up without a reservation, as long as the dune hasn't hit capacity, and they're let in ten minutes after a scheduled slot starts if there's room.
The published weekday and Saturday windows look like this:
| Day | Slot times |
|---|---|
| Monday through Thursday | 8:00 AM, 9:30 AM, 11:00 AM, 12:30 PM, 3:00 PM, 4:30 PM, 6:00 PM |
| Saturday | 8:00 AM, 9:30 AM, 11:00 AM, 12:30 PM, 3:00 PM, 4:30 PM |
Friday and Sunday aren't part of the city's published slot list, so don't assume the same rhythm holds on those days. Call the Parks and Recreation Department before you build a weekend habit around it.
The steps next to the dune have their own separate rule, and it has nothing to do with reservations. Signs posted along the stairway read "No Jogging." The distinction the city draws between jogging and walking follows something close to the standard used in competitive racewalking: one foot has to stay on the ground at all times. Fines for getting caught running the steps run higher than fines for dune violations. None of this reads like a rule a city writes on a slow afternoon. It reads like a rule written to end an argument.
The Fight That Built the Fence
The argument started well before the reservation system did. Sand Dune Park was built on a converted dump site by local residents back in 1964, when much of the surrounding area was still small beach cottages rather than the density Manhattan Beach carries today. For decades it stayed a quiet neighborhood park with a novelty feature. Then fitness culture caught up to it. Amateur and professional athletes started showing up specifically to train on the incline, and the dune started turning up in fitness magazines and newspaper features as one of the best conditioning workouts in Southern California.
Popularity is what broke the informal arrangement. By 2002, the Los Angeles Times was covering neighbor complaints about noise, traffic, and overcrowding, with residents calling for new limits on a park they said had become more popular with visitors from other cities than with the people who lived around it. The disagreement dragged on. In 2009, the debate reached the Los Angeles City Council chamber's Manhattan Beach counterpart, covered again by outside press, with the city weighing whether to restrict access altogether. The dune closed. It didn't reopen until August 2010, and only after the city built out what officials called substantial use mitigation measures, which is the polite civic phrase for the reservation system, the capacity cap, and the fines still in place today.
That's the piece easy to miss if you only know the dune as a workout spot. The permit and the fee aren't bureaucratic overreach layered onto a free park. They're the settlement terms from a fight the city almost lost twice, once to complaints and once to closure.
What the 2022 Work Actually Fixed
The city's own Parks Master Plan lists a project called Sand Dune Park Enhanced Nature Areas, completed in 2022, and the numbers behind it explain why the hillside looks different than it did a decade ago. The first phase involved pruning 294 trees, removing 38 that had failed or died, and hauling out nearly 100 tons of dead plant material that had piled up around the park over years of deferred maintenance. The second phase planted roughly 320 new trees and plants, installed jute netting across four hillsides to stop erosion, and replaced about 6,300 square feet of turf with decomposed granite.
None of that touched the sand dune's reservation rules. It addressed the ground around it, the part of the park that had quietly deteriorated while attention stayed fixed on the dune itself. Local coverage at the time framed it as the moment a decade of conflict finally gave way to something closer to a working peace between the neighborhood and the park.
The Next Rebuild Is Approved, Not Built
The city isn't done. On September 17, 2024, the City Council approved a conceptual design for a further Sand Dune Park renovation, budgeted at roughly $3.5 million. The plan includes new playground equipment, an outdoor education area with a low wooden stage and benches for school groups, upgraded pedestrian lighting throughout the park, two new prefabricated buildings in a Spanish-style finish to house an office and restrooms, and an artistically designed iron mesh fence funded through the city's public arts program.
One piece got cut before the vote. The original proposal included a six-foot concrete bike path across the park's south lawn. Nearby residents pushed back at the council meeting, and the council pulled the path from the plan before approving everything else 5 to 0. It's the same pattern as 2009: a use conflict, public pushback, and a design that survives with the contested element removed rather than the whole project scrapped.
As of the city's most recent Parks Master Plan update in June 2025, this redesign remained in the design and funding stage, with construction documents and additional funding allocations listed as the next steps rather than a groundbreaking date. If you live near Bell Avenue, the playground equipment currently there, along with the current restroom building, are on borrowed time. Nobody has said when the borrowed time runs out.
A Park With 163 Birds and One Very Specific Rule
Sand Dune Park carries one more detail worth knowing if you spend any time there beyond the workout. Bob Shanman of Wild Birds Unlimited has documented at least 163 different bird species in the park over the years, according to the city's own visitor information, making it one of the more productive bird watching spots in the South Bay for a park most people associate with quad burn rather than field glasses.
That's the shape of the place. A hundred feet of sand that draws a reservation line most mornings, 208 steps with their own racewalking-adjacent enforcement standard, four newly stabilized hillsides, 320 new plants, a redesign sitting in a funding queue, and 163 species of birds moving through all of it while the sand traffic sorts itself out below.
If you're weighing a move onto a street near 33rd and Bell, or you already live close enough to hear the dune attendant's tablet beep on Saturday mornings, it's worth understanding how a $3.5 million redesign in the funding queue might change parking, foot traffic, or the daily rhythm on your block before it breaks ground.
