Onion Valley to Kearsarge Pass Road — Inyo Mountains Eastern Sierra Approach
Straight up the Sierra's eastern wall.
Out of the baking Owens Valley floor near Independence, Onion Valley Road claws its way up the eastern face of the Sierra Nevada in a series of tight switchbacks and exposed shelf sections with nothing but air between your tires and the canyon below. The pavement ends and the gravel begins in earnest above 7,000 feet, where the road narrows and loose granite rubble tests your line selection all the way to the Onion Valley trailhead parking area at 9,200 feet. The views east across the Owens Valley to the White Mountains are the kind that make you pull over just to stare.
A stock 4WD with decent clearance handles this in good conditions, but the exposed shelf road demands focus — no room for distraction or sloppy steering. Trailers are a bad idea above the first switchback series. The road is typically open June through October depending on snowpack; check with Inyo National Forest before you commit. No permit is needed to drive up, but the John Muir Wilderness trailhead above requires a permit for overnight travel. Fuel in Independence before you go — there’s nothing up top. Dispersed camping is not available at the trailhead, but established campgrounds exist partway up.

Frequently asked questions
Can a stock 4Runner or Tacoma handle this road, or do I need a lift?
A stock 4WD high-clearance rig will get you through. Lifted helps on the rockier upper sections but isn't required — slow and deliberate gets it done.
When does the road typically open after winter, and is snow a real concern?
June is the realistic open window, though snow can linger into late June at the upper elevations near 9,200 feet. Check with Inyo National Forest before heading out — the upper road can close without much warning early or late in the season.
Do I need a permit or pay any fees to drive this road?
No permit or fee is required to drive the road itself. If you're hiking beyond Kearsarge Pass into the John Muir Wilderness, wilderness permits are required and quota-limited — grab those through Recreation.gov in advance.
What's the hardest part of the drive and what should I be ready for?
The upper switchbacks are the crux — loose rock, narrow shelf road, and steep exposure with limited room to pass oncoming traffic. Take it slow, stay right, and don't count on a guardrail to save you.
Is there any dispersed camping along the road, and how far is the nearest gas?
Onion Valley Campground sits at the top and is the primary option — dispersed camping along the road itself is limited. Gas up in Bishop (40+ miles north) or Lone Pine (20 miles south) before heading into Independence, because Independence has nothing.
