Mineral King Road — Three Rivers to Mineral King via Sequoia Backcountry High Valley
Marmots will eat your truck. Park anyway.
The Mineral King Road is the kind of road that filters itself. It starts at Three Rivers on the Sequoia park boundary and climbs 25 miles to a dead-end bowl at 7,800 feet — a former silver mining district that Walt Disney tried to turn into a ski resort before the Sierra Club stopped him. What’s left is a narrow, winding, deeply potholed two-lane that gains 6,000 feet through chaparral, canyon oak, and eventually subalpine fir, with Farewell Gap and the Sawtooth Ridge above. Marmots in the upper valley have a documented habit of chewing through vehicle wiring and radiator hoses for the salt — the NPS sells chicken wire enclosures at the ranger station and you should use one. The road closes below Atwell Mill at the first major snow, typically November, and often doesn’t reopen until late May.
The road is passable in a stock SUV with patience and a driver who doesn’t drift wide on blind corners. No true 4WD is required, but high clearance helps on the worst washboard and pothole sections in the lower canyon. It’s classified as a scenic drive, but the sheer drop exposures and narrow passing sections keep it honest. Permits are not required to drive the road itself, but wilderness permits are needed for overnight backpacking beyond the trailheads. Carry food secured against bears — the Mineral King bear box program is mandatory at the walk-in campsites. Best July through October; check NPS road conditions before you go.

Frequently asked questions
Can a stock SUV handle Mineral King Road, or do I need a lifted rig?
A stock SUV or even a patient passenger car can make it — this is a narrow, rough paved and dirt road, not a rock crawl. Ground clearance matters less than wheelbase; long-wheelbase trucks and trailers will struggle badly on the tight switchbacks. Leave the trailer at home.
When does Mineral King Road actually open each year?
Typically late May to late October, but snow can push that opening into June some years. The NPS gates the road in winter — check the NPS Road Conditions page before you go, because 'scheduled to open' and 'actually open' are two different things up here.
Do I need a permit or pay a fee to drive in?
Yes — Sequoia National Park charges an entrance fee (currently $35 per vehicle, valid 7 days). No separate permit is required just to drive the road, but if you're backpacking from Mineral King, wilderness permits are required and quota fills fast in summer.
What's the hardest part of this road and what should I actually expect?
The road is relentlessly narrow with 698 curves over 25 miles, crumbling edges, and zero guardrails on exposed sections — that's the whole trail, not just one hard spot. The difficulty is sustained stress and patience, not any single technical obstacle. Budget at least 90 minutes one-way and don't rush it.
What's the deal with marmots eating vehicles at Mineral King — is that actually real?
Completely real. Yellow-bellied marmots in the Mineral King valley have a documented habit of climbing into engine bays and chewing through coolant hoses, wiring, and belts — likely attracted to the warmth and soy-based wire insulation. Wrap your undercarriage in hardware cloth or chicken wire before parking overnight, or bring extra hose clamps and expect a repair session. The NPS even acknowledges it on their site.
