You can still legally drive a truck onto this California beach, and a boardwalk two miles south bans cars entirely
Most of California’s coastline banned cars off the sand decades ago. Oceano Dunes never got that memo — this is still the one California state park where you can drive a street-registered vehicle straight off the pavement and onto the beach, no permit lottery, no reservation fight, just a $5 gate fee.
The entry point is Post 2, about a mile south of the Pier Avenue kiosk in Grover Beach — that’s where the pavement ends and the sand-legal zone starts. Vehicles need current DMV registration either way, and the park runs vehicle day use daily from 7 a.m. to 10 p.m.

You can also just stay the night. Camping here means primitive beach and dune sites — no numbered spots, no picnic tables, just sand, a vault toilet somewhere within walking distance, and your rig parked a few feet from where you slept. Reservations run through Reserve California and open up to six months out.
Bring the right vehicle or don’t bother. Four-wheel drive is the honest requirement for the camping area — soft sand plus an incoming tide has stranded plenty of people who assumed a regular truck would be fine.
The dunes went dark for over a month this spring. A federal court found California State Parks had been violating the Endangered Species Act by allowing vehicle access too close to nesting western snowy plovers, and OHV access south of Arroyo Grande Creek shut down on April 14. It reopened May 21 after State Parks secured a 25-year incidental take permit from the U.S. Fish and Wildlife Service — worth a quick check before you load up the truck, since access has shifted more than once this year.
If engines aren’t your thing, walk two miles south instead. Oso Flaco Lake sits inside the same dune complex, but it’s the OHV area’s total opposite — no vehicles allowed anywhere on the trail or the beach it leads to.
The boardwalk covers 1.7 miles out and back with just 22 feet of elevation gain, rated easy, and crosses a 75-acre lake thick with waterfowl before dead-ending at a quiet stretch of sand. Dogs aren’t allowed, and the same $5 day-use fee applies.
Same dune system, same $5 gate — one side sounds like a motocross track, the other sounds like nothing at all. Which one you pick probably says something about what kind of trip you’re actually looking for.
Either spot pairs easily with a stop in nearby Pismo Beach, a few miles up the coast, if you want a pier and a boardwalk that isn’t buried in a dune.
Pack sunscreen either way — the wind off this stretch of coast doesn’t care which side of the fence you’re on.
Trip tips: grab a rental car to get out here, lock in your hotel before the good rooms are gone, or skip both and book a camper van instead.
Rules and fees change — always confirm current requirements before you go.
