Before you go
Cement Flats is closed to camping and all recreation from September 8, 2026 through February 2028. It's the temporary ranger station site. Don't plan to camp there.
Permit required — $55 in advance / $70 on site.
Coming from Arizona, the Sidewinder Chevron at Interstate 8 Exit 164 is the only fuel stop on the 8 before the Ogilby Road turnoff, as there is no fuel at Quechan Casino. Once you turn north up Ogilby there is nothing at all until Glamis, roughly 20 miles of empty desert, so fill in Yuma or at Sidewinder.

Full agency description
Glamis is the heart of the Algodones Dunes, officially the Imperial Sand Dunes Recreation Area and the largest mass of sand dunes in California. The dune field runs roughly 40 to 45 miles long and 5 miles wide, with peaks standing up to 300 feet above the desert floor — sand built from ancient Lake Cahuilla. The southern and central portions are open to off-highway vehicles and this is the world-famous end of it: big bowls, long runs, and a temporary city of camps over the winter holidays. North of Highway 78 the dunes become designated Wilderness and are closed to vehicles entirely.

Show all 14 area-specific rules
🪖 Sand car, sand rail, dune buggy, 4x4, or anything home-built or over 1,000cc: no helmet or seat-belt law applies. Wear them anyway — State Parks recommend it, and so do we.
🪖 Any helmet the law requires must meet Federal Motor Vehicle Safety Standard 218 and carry a DOT label.
Source: California Vehicle Code §500, §38505, §38601–38602, CVC 27802 — ohv.parks.ca.gov (checked Aug 2026).
15 MPH within 500 feet of Highway 78, Grays Well Road, Gecko Road, and the access roads inside Gecko and Roadrunner.
15 mph max within 50 feet of any camp.
14 day camping limit across the whole recreation area.
No saving or reserving a camping space for someone else.
No parking or camping within 10 feet of the pavement on Gecko Road.
Property left unattended more than 72 hours (24 in a day-use area) can be towed or removed.
These rules carry real penalties. Breaking BLM supplementary rules here can mean a fine of up to $1,000, up to 12 months imprisonment, or both, plus civil action. Flags, helmets and the 15 MPH zones are the ones people get cited for.
Standard OHV rules (12)
Common equipment, registration and trail-use rules still apply.
Ride to the highest safety standard, not the legal minimum. A helmet, eye protection, a flag and proper gear are what get you home.
Green sticker required year-round for registered OHVs.
No glass containers in the dunes.
Stay on designated OHV areas, closed ecological zones are enforced.
Safety flags required on all vehicles including two-wheeled motorcycles. Whip mast securely mounted, extending 8 feet from the ground, with a 6x12 inch red or orange flag within 10 inches of the tip.
Noise limit 96 dBA for machines built 1986 or later, 101 dBA for older.
🪖 Side-by-side / UTV (factory-built, steering wheel, bucket seats, under 1,000cc, does over 30 mph): helmets on the driver and every passenger, and seat belts or a harness fastened whenever it is moving. That is California law on public land.
🪖 Quads and ATVs: helmet on every rider, any age. Dirt bikes: helmet required under 18.
⚠️ Tuned it past 30 mph? A machine built for 30 or under that now goes faster is treated like a side-by-side, helmet and belt rules apply.
👶 A child seat does not replace a helmet. In a side-by-side, a child in a car seat still wears one.
Check the law yourself. These requirements come from California State Parks Off-Highway Motor Vehicle Recreation, rules change, and you are responsible for compliance.
