Current Status
Open as of September 16, 2026. Joshua Tree's public road-status layer listed Queen Valley Road, Big Horn Pass Road, and O'Dell Road as open on that date, with nothing closed anywhere in the park. The NPS road inventory has all three as existing native dirt with no seasonal gate, the backcountry roads page (last updated March 4, 2026) lists no closure, and the NPS alerts feed had nothing on these roads the same day.
Dirt roads across the park close temporarily after significant rain while flood damage is repaired, and driving around a locked gate draws a citation. Park-wide fire restrictions run June 15 through October 1, backcountry included. Closures are posted on the park's alerts and conditions page.
Getting Oriented
Queen Valley sits in the middle of the park, north of Park Boulevard and south of Queen Mountain, at roughly 4,260 to 4,470 feet. That is high enough for real winter weather; park photography from January 2021 shows snow on Big Horn Pass Road near the Wall Street Mill parking area.
Big Horn Pass Road is the direct way in, off Park Boulevard about seven-tenths of a mile west of the Geology Tour Road junction. Desert Queen Mine Road climbs 1.3 miles from that junction itself, past the Pine City trailhead, to the east end of Queen Valley Road. The west end comes out at the Barker Dam and Wall Street Mill trailheads, where paved Barker Dam Road takes over. With three connections to pavement rather than one, this drives as a loop instead of a set of dead ends.
The Three Roads
Queen Valley Road is the spine, 4.1 miles east to west across the valley floor. Park road data maps it as a single lane, which matters more than the surface does when a vehicle meets a group of cyclists.
Big Horn Pass Road is 2.3 miles and two lanes, the shortest way up from Park Boulevard, and the road the Park Service suggests starting a bike trip on.
O'Dell Road runs 1.5 miles north off Big Horn Pass Road toward Queen Mountain, ending at a turnaround about eight-tenths of a mile short of Queen Valley Road. It is a spur off the loop, not a third way across.
Those three total about 7.9 miles of mapped centerline. The 13.4-mile figure on the NPS page covers the network with its spurs and paved Barker Dam Road.
Trail Overview
Surface is native dirt, close to level across the valley, past the boulder piles and Joshua trees the Park Service lists as the reason to come. The park's backcountry roads page describes seven road systems, and this is the only one it does not mark high clearance and four-wheel drive. The park's road status layer draws the same line, flagging every other dirt backcountry route as 4x4 and these three as not. That rating describes normal conditions, not a road after a storm.
Bikes stay on roads open to vehicles and off the trails, and the Park Service recommends the backcountry network over the paved loop for its lighter traffic. The park's only two bike racks are at the west end of this network. ATVs, UTVs, and dirt bikes are prohibited, dual-sport motorcycles must be street-legal and registered under California law, and everything stays on the designated roadway.
Points of Interest
- Queen Mountain, north of the valley and in view across most of the network.
- Pine City trailhead, at the top of Desert Queen Mine Road at 34.0237, -116.0777. The park's caption on its own Queen Valley photograph recommends stopping there for a short hike.
- Wall Street Mill and Barker Dam trailheads, side by side at the west end near 34.0252, -116.1418, where the dirt meets pavement and one of the park's two bike racks sits. The other is at the Echo T, a mile further west at 34.0228, -116.1562.
Where to Camp
Camping along Joshua Tree's backcountry roads is prohibited, covering car camping, dispersed camping, fires, and drone use. None of these three roads is an overnight.
Hidden Valley Campground is the closest developed site to the west end, 44 sites on Park Boulevard, first-come first-served year round at $25, vault toilets and no water. Ryan Campground, south on Park Boulevard, has 32 reservable sites at $30 plus the park's three bicycle sites at $5 a night. Ryan has no water either; the Park Service sends cyclists to the West Entrance station or park headquarters to fill up.
Overnight backcountry camping falls in the Pine City zone on a $6 Recreation.gov permit, with sites at least half a mile from any road and a mile from any backcountry trailhead. Pine City stays open through the summer, unlike Pleasant Valley and the park's southern and eastern zones, which close June 1 through September 1.
Tips for a Safe and Enjoyable Trip
- Fill the tank and load water before entering. Joshua Tree has no fuel, food, or lodging inside the boundary and no water in its interior.
- Carry a fully inflated spare plus a jack, lug wrench, shovel, tow strap, and basic tools. The Park Service expects drivers on these roads to be able to self-rescue, and warns that help can take hours or days.
- Cell reception is very limited park-wide. NPS recommends a satellite communicator and printed topographic maps alongside GPS.
- Expect to meet cyclists on a one-lane road, particularly between Barker Dam and the Pine City trailhead.
- Winter puts snow and ice on this ground. Summer highs run near or above 100°F, and the park advises carrying extra ice and water in case air conditioning fails.
- Entrance is $30 per private vehicle for seven days, $25 per motorcycle, $15 on foot or bicycle. The park's number is 760-367-5500.
Fuel and Water
There is no fuel and no water on this network. The Park Service states that Joshua Tree has no gas stations, restaurants, grocery stores, or hotels inside the boundary, and no water available in the interior of the park.
Twentynine Palms is the nearest town on the north side, with the town of Joshua Tree and Yucca Valley on the west. Hidden Valley, Ryan, and Jumbo Rocks are dry; the park's only year-round potable water is at Black Rock and Cottonwood, both well away from Queen Valley.
Nearby
Geology Tour Road turns south off Park Boulevard in the same corridor, 5.4 miles down to Paac Kü̱vü̱hü̱’k plus a six-mile loop through Pleasant Valley, rated high clearance and four-wheel drive.
Berdoo Canyon Road leaves the south end of Geology Tour Road for 11.5 miles of deep sand, sharp bedrock, and two rock pinches down to Dillon Road.
Barker Dam, Wall Street Mill, and Hidden Valley are short walks off the west end.
