South Eureka Valley Road is the county-maintained approach to the Eureka Dunes, in the far northwest corner of Death Valley National Park. The Park Service rates it high-clearance and flags heavy washboard along its length and deep sand as it nears the dune field.
The dunes rise close to 700 feet off the playa, the tallest in California. Past them the road becomes Steel Pass Road and the rating jumps to rough four-wheel drive.
Deep sand near the dunes. The Park Service calls this out by name. Sand is the most likely place to get stuck on the county-maintained section.
Heavy washboard. Present along South Eureka Valley Road and worse on the Big Pine Road approach. Flat tires are very common on the park's backcountry roads, and all-season or street tires may not be suitable.
Approach road closures. Big Pine Road is occasionally closed by snow and flood damage. Check the park's conditions page before leaving.
Heat. Summer brings extreme dehydration and heat-stroke potential. The park advises against low-elevation hiking between May and October.
Flash floods. Do not camp in dry washes or drainages.
No cell service. Most of the park's backcountry has none, and Eureka Valley is among the most isolated ground in it.
Recovery cost. Towing from a dirt road in Death Valley often exceeds $2,000. Rental agreements usually prohibit off-pavement driving and exclude recovery, and rentals often ship without a full-size spare.
Hantavirus and rattlesnakes. Avoid disturbing rodent signs or sheltering in old structures, and watch for snakes near vegetation around water.

The approach is Big Pine Road, signed in places as Death Valley Road, running east from Big Pine on US 395 toward the park's northern boundary. The Park Service rates it high-clearance and warns of dust, heavy washboard, and large drainage dips. Its final section from Eureka Valley west to Highway 168 is paved.
South Eureka Valley Road turns south off Big Pine Road and runs down the valley to the dunes and the primitive campground at their base. It is county-maintained the whole way to the dunes.
Beyond the dunes the same road becomes Steel Pass Road and climbs south toward Saline Valley as a rough four-wheel-drive route. That is a different class of driving in a different class of vehicle.
North Eureka Valley Road, also county-maintained and rated high-clearance, runs the other direction and often needs four-wheel drive to reach Highway 168.

Checked 16 September 2026 against the park's road conditions page, last updated 4 September 2026: South Eureka Valley Road has no closure and no posted caution, and neither does Big Pine Road, the road in from US 395. The Eureka Dunes primitive campground at the end of the drive was listed open on the same date.
Elsewhere in the park, Darwin Falls Road is closed and likely to stay closed into summer 2027. Hunter Mountain Road is closed for mud deep enough to have stranded multiple vehicles. The last three miles of Phinney Canyon Road are washed out and impassable to all vehicles. Titus Canyon Road is temporarily open after initial repairs and closes for a full year of work from 1 October 2026 through 30 September 2027. Harry Wade Road has a deep-sand caution posted about six miles south of its Badwater Road junction.
None of those touch this drive. Big Pine Road does. It is open now, but snow and flood damage shut it from time to time, and that is what usually ends a trip out here before it starts.
Eureka Valley is the park's far northwest corner, well outside the loop most visitors drive. The way in is Big Pine Road, signed in places as Death Valley Road, which the Park Service rates high-clearance and describes as dusty and heavily washboarded with large drainage dips. Its final section, from Eureka Valley west toward Highway 168, is paved. South Eureka Valley Road turns off it and runs south down the valley floor to the dune field.
The dunes themselves cover roughly three miles by one mile and rise more than 680 feet off a dry lakebed at about 3,000 feet of elevation, the tallest in California and possibly the tallest in North America. When the sand is completely dry, grains avalanching down the lee faces make a low sound the Park Service likens to a bass organ note or a distant aircraft. Damp sand stays quiet.
Three plants grow here and nowhere else on earth. Eureka dunegrass is federally threatened, shining milkvetch is a candidate for listing, and the Eureka Dunes evening primrose blooms at night. Five beetle species are endemic to the dunes as well.
The Park Service rates the county-maintained section to the dunes as high-clearance, with heavy washboard along its length and deep sand as the road nears the dune field. Sand is where stock vehicles get into trouble on this drive. The park's standard for high clearance is at least 15-inch tire rims and eight inches from the lowest point of the undercarriage to the ground, which rules out every sedan.
Past the dunes the road becomes Steel Pass Road and the rating changes entirely: rough four-wheel drive with sustained technical sections and narrow bedrock steps needing careful wheel placement to avoid damage. The Park Service says travel runs easier north to south, calls the stretch experienced-drivers-only, and describes it as one of the most remote corners of the park. Treat it as a separate trip rather than a continuation of this one.
Flats are routine on the park's backcountry roads, and the park warns that all-season and street tires may not be suitable. Rental contracts are worth reading before the turnoff, since most prohibit off-pavement driving and exclude towing and recovery, and a tow off a dirt road here runs past $2,000.
Eureka Dunes Campground sits at the base of the dunes at 2,880 feet. It is free, primitive, and first-come, with vault toilets open year-round and no water. The Park Service records it as accessible only to high-clearance vehicles.
Camping on the dunes is prohibited outright, and the park asks people camping outside the campground to pitch away from the dune base, where the endemic plants and animals are concentrated. Dispersed camping elsewhere in the park has to be at least a mile from any developed area, paved road, or day-use-only road, and at least 100 feet from any water source. Group size is capped at 12 people and four vehicles. An overnight backcountry permit is voluntary and available at Furnace Creek Visitor Center or Stovepipe Wells Ranger Station during open hours.
Campfires are allowed only in Park Service firepits, and gathering firewood is prohibited.
There is no fuel, no water, and no service of any kind at the dunes or anywhere on South Eureka Valley Road.
Inside the park, gasoline is sold around the clock at Furnace Creek and Stovepipe Wells, and Panamint Springs Resort sells fuel daily from 7:00 a.m. to 9:30 p.m. All three sit a long way from Eureka Valley, so the practical fill-up for an approach along Big Pine Road is Big Pine, on US 395.
Carry all drinking water. Natural springs in the park are unmonitored, occasionally contaminated, and should be purified if used at all.
Steel Pass Road picks up where this road ends and runs south to Saline Valley, experienced drivers only.
North Eureka Valley Road runs the other way, out to Highway 168, and reaches the Sylvania Mountain Wilderness outside the park's northern boundary. Cucomungo Canyon Road forks east from it to Highway 266 in Nevada.
Saline Valley Road's north section connects Big Pine Road south to the Warm Springs junction. The Park Service rates that stretch high-clearance county-maintained dirt with heavy washboard, occasionally closed by rockfall, snow, and ice at its 7,200-foot pass.
