Mineral King Road — Sequoia’s Switchback Gauntlet to the High Sierra Subalpine
Marmots eat brake lines. Bring spares.
Mineral King Road earns its reputation before you’re halfway in. Starting at the Three Rivers junction on Highway 198, this 25-mile stretch of mostly unpaved, single-lane road climbs nearly 6,000 feet into one of the Sierra Nevada’s most stunning subalpine basins — a place miners chased silver in the 1870s and Walt Disney once tried to bulldoze into a ski resort. The road clings to canyon walls above the East Fork Kaweah River, with blind corners, sheer drop-offs, and no guardrails for long stretches. The final approach into Mineral King Valley opens onto a hanging basin ringed by peaks topping 12,000 feet, with the historic Mineral King Pack Station and ranger cabin sitting dead center like something out of 1920.
The road is passable for most high-clearance vehicles, but long wheelbases suffer on the tight switchbacks — keep it under 22 feet total. Marmots will chew your brake lines; wrap them before you leave. The road typically opens late May and closes after the first heavy October snow. No permit is needed to drive it, but you’ll need a Sequoia National Park pass. Fuel up in Three Rivers — there’s nothing past the gate. Cell service disappears fast. Bring water, a tow strap, and patience for tourist traffic on the lower section.

Frequently asked questions
Can a stock 4Runner or Tacoma handle Mineral King Road, or do I need a lift?
A stock 4Runner or Tacoma handles it fine. High-clearance 2WD can technically make it in dry conditions, but the narrow switchbacks, loose gravel, and occasional rocky sections make 4WD a real advantage. Lifted rigs aren't required — clearance matters more than a locker here.
When does Mineral King Road actually open each year, and can I drive it after the first snow?
The road typically opens in late May or early June depending on snowpack, and closes in late October or early November. After the first significant snow it's done — NPS gates it off and there's no plowing. Check the NPS Sequoia road conditions page before you leave home.
Do I need a permit to drive in, and is there an entrance fee?
Yes, Sequoia National Park charges the standard NPS entrance fee — currently $35 per vehicle for a 7-day pass. No additional permit is required just to drive Mineral King Road, but if you're backpacking from the trailheads at the end, you'll need a wilderness permit. America the Beautiful passes are accepted.
What's the hardest section of Mineral King Road and what actually makes it dangerous?
The worst stretches are the upper switchbacks in the final 10 miles — tight enough that two vehicles meeting requires one to back up to a pullout, with crumbling asphalt edges dropping off into the canyon. The road is genuinely narrow with minimal guardrails; the danger is inattention and meeting oncoming traffic on a blind corner, not extreme technical obstacles.
Why does the tagline mention marmots eating brake lines — is that actually a thing I need to worry about?
It's completely real. Yellow-bellied marmots at the Mineral King trailhead parking area have a well-documented habit of chewing brake lines, wiring, and rubber hoses on parked vehicles — apparently attracted to road salt or coolant residue. Wrap your undercarriage in chicken wire or use the provided chicken wire fencing at the lot, and don't leave your rig parked overnight without protection.
