White Mountains Inyo National Forest Backway
Ancient trees, high-altitude desert solitude
At 10,000 feet, you’re driving through groves of bristlecone pines that were alive when Rome fell. The White Mountain Road climbs from the Owens Valley floor through pinyon-juniper country into the ancient forest, where some trees are over 4,000 years old. The rocky, winding track passes the Schulman Grove visitor area before continuing north along the ridge, offering unobstructed views of the Sierra Nevada across the valley below.
This is moderate 4×4 territory — high clearance essential, low range recommended for the steeper pitches. The road can be rough with embedded rocks and loose sections, but it’s generally manageable for experienced drivers. Best tackled June through October when snow clears. Fuel up in Bishop and carry extra water; this high desert country will dehydrate you fast. What you get is solitude among the world’s oldest living trees and some of the most expansive mountain views in California.

Frequently asked questions
Do I need 4WD or will high-clearance 2WD work on this trail?
You need 4WD. The rocky terrain, steep grades, and loose surfaces at altitude will have you spinning tires without four-wheel drive.
When does snow typically close this trail?
Usually closed November through May due to snow at elevation. June can still have patches above 10,000 feet, so check current conditions with Inyo National Forest before heading up.
Are there any permits required for the White Mountains Backway?
No permits needed for driving the trail or dispersed camping. It's National Forest land with standard fire restrictions during dry seasons.
What's the hardest part of this trail?
The steep, rocky climbs above 9,000 feet where the trail gets narrow with loose shale. Take your time and pick your lines carefully on the switchbacks.
How much gas should I have before starting from Bishop?
Fill up in Bishop - you'll burn more fuel at altitude and in 4WD. The 28-mile trail plus getting back to town could easily use a half tank depending on your rig.
