Mineral King Road
698 switchbacks to Sierra high country
The locals in Three Rivers will tell you straight: Mineral King Road has exactly 698 switchbacks carved into the Sierra Nevada granite, and every one of them earned its place the hard way. This 25-mile dirt ribbon climbs 6,200 vertical feet from the Central Valley heat to 7,500 feet of alpine meadows, following a route that started as a mining trail in the 1870s when silver fever had men hauling equipment up impossible grades. Your modern rig will face the same narrow shelf road they did, though hopefully with better brakes.
The road demands respect but doesn’t require a built rig—a stock SUV with high clearance will make the journey, though low-hanging skid plates might kiss granite on the tighter switchbacks. The surface stays mostly packed dirt with occasional loose rock sections, but the real challenge is the exposure and the width. Two vehicles meeting means one backs up to the nearest pullout, and those pullouts come maybe every half-mile if you’re lucky. Water crossings appear in early season as snowmelt runs across the road, nothing deep but enough to keep you honest. Cell service disappears after the first few miles and stays gone until you turn around.
June through October marks the viable season—snow closes the upper reaches completely through winter and spring. The National Park Service maintains it as a scenic drive rather than a trail, but maintenance up here means clearing rockfall and grading the worst washouts, not paving paradise. Fuel up in Three Rivers because there’s nothing past the pavement, and plan a full day if you’re camping or hiking from the end. The road terminates at Mineral King Valley, where the real Sierra backcountry begins and day hikers disappear into country that looks exactly like the John Muir photographs.
What you get for those 698 turns is access to one of Sequoia National Park’s most remote valleys, surrounded by 12,000-foot peaks and meadows that explode with wildflowers in July. It’s not technical wheeling—it’s mountain driving that separates the committed from the casual, delivering you to trailheads where you might see more marmots than people. The road itself becomes part of the adventure, not just the route to it.

Frequently asked questions
Can a stock Tacoma or 4Runner handle Mineral King Road without modifications?
Yes, a stock high-clearance truck or SUV handles it fine. The road is narrow and rough with some rocky sections, but it's the 698 tight switchbacks — not the terrain — that'll test you. Low-hanging body kits and long-wheelbase rigs will have a harder time negotiating the sharper turns.
When does Mineral King Road open and close each year?
Typically opens in late May or early June and closes in late October or early November, depending on snowpack. The NPS gates the road at both ends off-season — check nps.gov/seki before you go, because the dates shift year to year.
Do you need a permit or pay a fee to drive Mineral King Road?
No permit is required to drive the road itself, but you're entering Sequoia National Park — the standard park entrance fee applies ($35 per vehicle as of 2024). If you're camping at Atwell Mill or Cold Springs campground at the end, reserve those sites through Recreation.gov, especially on summer weekends.
What's the hardest section of the road and what should I actually expect?
The switchbacks above the lower canyon are relentless — narrow, no guardrails, and with oncoming traffic it's a white-knuckle passing game on blind corners. The road surface is rough dirt and loose rock throughout; nothing technical, but the exposure and tight turns demand full attention for nearly all 25 miles.
Is there any gas or services once you leave Three Rivers, and what about marmots damaging vehicles?
Zero services past Three Rivers — fuel up before you leave town. More importantly: the marmots at Mineral King are infamous for chewing through engine wiring, hoses, and belts. Bring a tarp or hardware cloth to wrap your undercarriage before you leave your rig overnight — this is not a joke, it's a real and expensive problem up there.
