Waucoba-Saline Valley Road — Inyo Mountains Crest to Saline Valley Hot Springs via Steel Pass
Steel Pass into Saline: earn your soak.
Steel Pass is not a road you stumble onto by accident. At roughly 7,200 feet, this rocky notch in the Inyo Mountains connects the Owens Valley to one of Death Valley’s most isolated basins — the Saline Valley. The approach from Big Pine climbs through pinyon-juniper country on Waucoba Road before the trail turns gnarly at Steel Pass itself, where loose shale, embedded boulders, and off-camber shelf road will test your rock-stacking patience and your locker engagement. Drop down the west wall of the Inyo Crest and you enter another world entirely — saltpan flats, wild burros, and the famous Saline Valley Warm Springs, a remote, clothing-optional oasis run by volunteers who have been maintaining those concrete tubs since the 1960s.
This is expert terrain. Short-wheelbase rigs with full lockers, a lift, and meaty tires have the best shot at Steel Pass — longer trucks and trailers should not attempt the descent. Carry at minimum three gallons of water per person; there is no reliable source until the hot springs. Fuel in Big Pine before you go — it’s 80-plus miles round trip into the basin with no services. No permits required for most of the route, but some sections pass through Death Valley National Park requiring a fee. Best window is October through April; summer heat in the Saline Valley floor can be lethal. The payoff is complete solitude, epic geology, and a hot soak under the Milky Way.

Frequently asked questions
Can a stock Tacoma or 4Runner run this trail, or do I actually need lockers?
Steel Pass is not a stock-truck trail. The rocky descent off the crest has loose, off-camber sections where a rear locker is the difference between driving out and winching. High clearance is non-negotiable — figure at least 10 inches of ground clearance and a skid-protected undercarriage.
When is this trail passable and what closes it?
October through April is the window — summer heat in Saline Valley routinely exceeds 115°F and has killed people. Winter snow can close the Inyo crest section, so check road conditions with the BLM Bishop Field Office before committing. Spring flash floods can also wash out sections with zero warning.
Do I need a permit to drive through and camp at Saline Valley Hot Springs?
The hot springs sit inside Death Valley National Park, so a valid DEVA entry permit or America the Beautiful pass is required. There's no fee station out there — rangers do patrol and will write citations. No campfire permits are needed for dispersed camping, but fires may be restricted seasonally.
What's the hardest section of this route and what actually makes it dangerous?
Steel Pass itself is the crux — a loose, rocky climb and descent with ledges, off-camber shelf road, and no room to turn around in spots. The danger isn't just mechanical; it's 68 miles of zero cell service and limited rescue access, so a breakdown or rollover means you're waiting on whoever you told your trip plan to.
How much water and fuel do I need to carry for this route?
Fuel up in Big Pine before you leave — there is no gas between Big Pine and anywhere useful on the other end. Carry a minimum 5-gallon fuel reserve for the full route. Water at the hot springs is not potable, so bring all drinking water from town — plan at least a gallon per person per day plus extra for a radiator emergency in that heat.
