Oceano Dunes Closure Update: Fees, Rules, and Plover Closures

Oceano Dunes State Vehicular Recreation Area is open, and the state-level fight over closing it to off-highway vehicles ended in 2025 when California’s Second District Court of Appeal ruled against the Coastal Commission and the state Supreme Court declined to review the case. Visiting still means working within a set of Oceano Dunes rules and closures: daily vehicle caps, mandatory safety equipment, posted riding zones, and a seven-month seasonal closure for nesting shorebirds. A separate federal Endangered Species Act case decided in November 2025 could change access again depending on what remedies the court orders.

Getting In: Daily Caps, Fees, and Registration

California State Parks caps daily access at 1,000 street-legal vehicles and 1,000 off-highway vehicles carrying a green or red DMV sticker.¹ Staff count vehicles at the gates. When either category fills, the gates close until vehicles leave. On summer weekends and holidays, arriving after mid-morning risks being turned away.

Day-use entry is $5 per vehicle.² Every vehicle on the sand must meet California registration requirements, and off-highway vehicles must display a current green or red DMV sticker.³

Equipment You Must Have

Every vehicle recreating at Oceano Dunes needs a whip and flag. The whip, a pole or antenna securely mounted to the vehicle, has to extend at least eight feet from the ground and stand upright when the vehicle is stopped. The flag must be solid red or orange, at least 6 by 12 inches, and mounted within 10 inches of the whip’s top.³ Rangers turn away vehicles without one.

If you are operating a recreational off-highway vehicle such as a side-by-side or UTV, additional California Vehicle Code rules apply:

All operators and passengers must wear a DOT-certified safety helmet, regardless of age or seat position.⁴
Everyone in the vehicle must wear a properly fastened seatbelt, shoulder belt, or safety harness while it is moving.⁴
In 2014 and newer ROVs, passengers may only occupy manufacturer-designed seats. Extra seats and riding in cargo areas are not allowed.⁴
Operators must be at least 16, or under the direct supervision of a parent or guardian.⁴

A common mistake: assuming a child in a car seat is exempt from the helmet rule. They are not. It applies to every person in the vehicle.

Where and How Fast You Can Ride

The speed limit on the beach, along the shoreline, and near campsites or any group of people is 15 miles per hour.³ State park peace officers enforce this and cite on the spot.

Numbered posts divide the park into zones with different rules. Street-legal vehicles are generally restricted to the beach corridor. Registered off-highway vehicles can also access the open dune riding area to the south. The District Superintendent sets these boundaries, and they are posted on maps at the park.⁵ Riding beyond fence lines or onto vegetated areas is prohibited.

Before driving a street-legal vehicle onto the sand for the first time, drop your tire pressure to roughly 10 to 12 PSI. Air stations near the park entrance let you re-inflate on the way out. Running highway pressure on sand is the fastest way to get stuck.

Seasonal Closures for Snowy Plovers

Western snowy plovers nest at Oceano Dunes from March 1 through September 30. During those seven months, fenced exclosures between roughly Post 4 and Post 7 are closed to all public entry, including vehicles, pedestrians, and dogs.⁶ The shoreline west of the foredune closure also closes during breeding season.

Parts of the southern exclosure have been closed year-round since October 2021.⁶ Between March and September the rideable area shrinks noticeably. Check the maps posted at the entrance on the day you visit, because closure boundaries shift slightly from year to year based on where nesting concentrates.

Camping

Camping at Oceano Dunes is primitive: no designated sites, no hookups, vault and chemical toilets only. You pull your vehicle onto the sand and set up. State Parks recommends four-wheel drive because two-wheel-drive vehicles routinely get stuck.²

All camping requires an advance reservation through ReserveCalifornia, and the window opens six months before arrival.² Capacity is capped at about 150 units at a time because of habitat conservation requirements, so weekends from May through October fill early. Check ReserveCalifornia for current nightly rates.

Non-Motorized Options

The park also supports hiking, horseback riding, surfing, surf fishing, and wildlife viewing. Areas fenced from vehicles for habitat protection are good for birdwatching. Oso Flaco Lake, a freshwater lake connected to the dune complex, has a boardwalk through wetlands. Dogs are not allowed at Oso Flaco Lake or at the Pismo State Beach Dune Preserve.²

What Could Still Change

The Coastal Commission case is over, but a separate federal lawsuit is not. In November 2025, a federal court found that off-road vehicle activity at Oceano Dunes harms and kills western snowy plovers in violation of the federal Endangered Species Act. That case was brought on different legal grounds than the state closure fight, and the practical effect on visitors depends on what remedies the court orders. Possible outcomes range from expanded seasonal closures to broader restrictions on where and when vehicles can operate. If you are planning trips well into the future, watch this case, because it could change park operations in ways the state courts did not.
