Sequoia & Kings Canyon: Big Trees and the Generals Highway

Sequoia and Kings Canyon are two national parks on one ticket, and in 2026 you still do not need a timed-entry reservation to drive in. A private car is $35 for up to seven days. If you’re not a US resident and you’re 16 or older, add $100 per person unless you show an Annual or America the Beautiful pass. That’s the whole gate math. The rest of the trip is about which entrance your vehicle can actually use.

People treat this as Yosemite’s quieter cousin and then spend a Saturday circling the Sherman Tree lot at noon. The trees are the point. The road is the trap. You’ll feel that the first time the Sherman lot is full at 11 a.m. and the only empty pavement is Wolverton.

Two parks, one booth, no timed ticket

The National Park Service runs Sequoia and Kings Canyon as a single unit. One entrance pass covers both, plus the Hume Lake District of Sequoia National Forest. Sequoia holds the Foothills, Giant Forest, Lodgepole, Wuksachi and Mineral King. Kings Canyon holds Grant Grove and Cedar Grove. Drive the Generals Highway between them and you cross national forest land, where some rules change. Pets, fires and food storage are the usual surprises.

The parks are open 24 hours a day, 365 days a year. Winter storms close roads until they’re plowed. That’s not a reservation system. It’s weather.

Entrance stations at Ash Mountain and Big Stump take cards and digital wallets only. If you need to pay cash, buy the $35 vehicle pass first at the Sequoia Parks Conservancy store in the Foothills Visitor Center or at the Kings Canyon Visitor Center in Grant Grove. Don’t show up at the booth with twenties and a speech.

The 2026 surcharge is the same list you’ve already met at Yosemite: eleven busy parks, $100 per nonresident adult on top of the standard fee. Two overseas adults in one car pay $235 here, or $250 for the America the Beautiful Non-Resident Annual, which covers the whole private vehicle at parks that charge per car like this one. Annual (holder plus three other adults, every federal fee site for a year). If this is your only listed park, pay the surcharge. If you’re stacking Yosemite later, buy the pass first. The America the Beautiful Pass page does the break-even math. Fee-free days in 2026 are for US residents only.

Sherman is volume, not height

Coast redwoods on California’s north coast are taller. General Sherman is fatter. NPS lists it at 274.9 feet, a maximum base diameter of 36.5 feet, 102.6 feet around at ground level, and about 52,500 cubic feet of trunk. The fact sheet puts its age around 2,200 years. That’s the tree people fly in to stand next to, and it’s a half-mile downhill paved walk from the main lot off Wolverton Road. The walk back is uphill. Budget the uphill.

A fence protects shallow roots. Stay on the pavement. In 2021 firefighters wrapped the lower trunk in foil as the KNP Complex Fire pushed into Giant Forest. The tree survived. Plenty of other monarchs in these parks did not.

A disability placard unlocks a short accessible trail from a small lot on the Generals Highway. In shuttle season you can ride a wheelchair-accessible bus there and skip the climb. After the photo, the paved two-mile Congress Trail is the better hour: more named trees, fewer people posing.

Giant Forest sits about a mile above the San Joaquin Valley orchards. The museum is at 6,409 feet, Sherman at 6,906. Foothills Visitor Center, where you entered if you came up Highway 198, is 1,720 feet and can be 30 degrees warmer. Pack a layer even in August.

Pick the gate by how long your vehicle is

This is the decision that wrecks rental-RV weekends.

Highway 198 through Three Rivers (Ash Mountain entrance) is the scenic climb: river, switchbacks, then sequoias. NPS does not advise vehicles longer than 24 feet between the Foothills Visitor Center and Potwisha Campground, or longer than 22 feet from Potwisha to Giant Forest Museum. The Moro Rock / Crescent Meadow spur is a hard 22-foot restriction, not a suggestion. Crystal Cave Road is the same 22-foot ban.

Highway 180 from Fresno (Big Stump entrance) is the grown-up road: straighter, less steep, wider. If you’re in anything that feels like a small bus, start here. Grant Grove is just inside. Giant Forest is then a 30-mile, roughly 65-minute drive south on the Generals Highway.

Drive times from the cities, per NPS: Fresno to Big Stump, 60 miles, about 1 hour 15 minutes. Visalia to Ash Mountain, 36 miles, about 45 minutes. Fresno Yosemite International (FAT) is about 1 hour 15 minutes from the Kings Canyon gate and 1 hour 45 minutes from Sequoia. Turn off “avoid tolls” on your map app. The park warns that GPS will happily send you onto gated forest roads that look like shortcuts and aren’t.

There is no gas and no EV charging inside park boundaries. Hume Lake Village (year-round) and Stony Creek Resort (summer only), both on national forest land, sell fuel when they are open - call ahead. Fill up in Three Rivers, Visalia or Fresno.

From the Friday after January 1 to the third Friday in March, the Generals Highway between the parks is unplowed and often closed. A winter trip that wants both Giant Forest and Grant Grove may have to drop all the way back to the foothills and come up the other highway. Chains can be required any time it snows. Rental contracts that forbid chains are a real problem here - see driving in the USA before you assume the compact will be enough.

The fare-free in-park shuttle is a summer service - the 2026 season is May 22 through September 7 - and it runs in Sequoia only, with no buses in Kings Canyon. Route 1 links Giant Forest Museum, Sherman and Lodgepole; Route 2 does Moro Rock and Crescent Meadow; Route 4 is Sherman to Wolverton; Route 3 (Lodgepole to Wuksachi) is weekends and holidays. The trip planner puts them at 8:30 a.m. to 6 p.m. Sherman and Giant Forest Museum lots fill by mid-morning. Park at Wolverton or Lodgepole and ride.

The City of Visalia’s Sequoia Shuttle is $15 round trip, reservation required, and seasonal: the 2026 dates are May 21 through September 7. It does not include a park pass, and the $35 vehicle pass is no help here: it covers everyone in a private car, and on the bus you are not in one. Shuttle riders pay the walk-in rate of $20 each from age 16, with under-16s free. You won’t reach Grant Grove or Cedar Grove on this bus. NPS is blunt about that.

Crystal Cave eats a half day on purpose

Crystal Cave is a marble cavern with a spider-web gate and a 50-minute guided tour run by Sequoia Parks Conservancy. The 2026 season is May 22 through November 1. Tickets are $22 for adults and $11 for children, sold only online by the Conservancy, not by the park. July and August sell out. Book at least 30 days ahead; NPS will sell as late as 36 hours out, which is how you get shut out. Confirm the child age cutoff on the booking page - the listing prints the price, not the age.

The cave is 50°F, so you’ll want a jacket even in August. The walk in is a steep half-mile with stairs the Conservancy compares to a 20-story building. Strollers and baby backpacks are not allowed, and the paved trail down has stairs and uneven ground, so it cannot take a wheelchair. From the Sequoia entrance, plan at least 1.5 hours to the parking lot; from Kings Canyon, at least 2 hours. Weekend booth lines can add another hour. The tour ticket is not a park pass. Vehicles over 22 feet and trailers are banned on Cave Road. After a four-year fire-and-storm closure, the first weeks of the 2025 season sold out. Treat 2026 the same way.

Kings Canyon is the empty half

Grant Grove is the easy Kings Canyon: the General Grant Tree, second-largest by trunk volume at 46,608 cubic feet, on a one-third-mile paved loop. You can do it in an hour and be back at the visitor center. That’s the half of Kings Canyon most people see.

The namesake canyon is Cedar Grove, about 29 miles and an hour beyond Grant Grove on Highway 180. NPS calls it one of the least crowded corners of either park. Elevation 4,600 feet, so summer days run 80 to 95°F while Giant Forest is still cool. Zumwalt Meadow, the River Trail, Mist Falls and Road’s End (wilderness permits, Rae Lakes) are why you came this far. The lodge has 21 rooms and is listed as open May through mid-October. The road itself is generally open from the fourth Friday in April to mid-November, then Caltrans gates it for rockfall. Check the live table on nps.gov or call (559) 565-3341, press 1, then 1.

Drowning is the primary cause of death in these parks. Spring snowmelt makes the Kings and the Kaweah fast and cold. Rocks at the edge are slick. Don’t put kids on the bank for a photo. Bears in Cedar Grove will open a car for toothpaste. Food goes in the metal boxes, including at day-use trailheads.

Mineral King is a steep dead-end road about 30 miles and an hour and a half from Three Rivers, generally open the Wednesday before Memorial Day to the last Wednesday in October. Major roadworks run through 2026 and 2027, with weekday closures and delays across spring, summer and autumn - check the park page before you commit a day to it. RVs and trailers aren’t allowed in those campgrounds. No road crosses the Sierra through these parks. Mt. Whitney, 14,494 feet, is in the unit. You don’t drive to it from Giant Forest.

Sleep in Three Rivers, Wuksachi or Grant Grove

In-park beds are Wuksachi Lodge (7,057 feet), Grant Grove, and seasonal Cedar Grove. The concessionaire’s own pages disagree on whether Wuksachi runs all year, so check dates on visitsequoia.com rather than assuming a winter room. Book through visitsequoia.com or (866) 807-3598. Don’t treat a scraped hotel-site number as the rate.

Three Rivers is the practical Ash Mountain base: minutes from the booth, gas, food that isn’t lodge food. Visalia is cheaper and sits on the shuttle. Fresno is the airport and the Highway 180 start. Grant Grove works if you want to wake up in sequoias and drive to Cedar Grove without backtracking.

Don’t “add Sequoia as a half day” onto Yosemite. Giant Forest to the valley is not a commute. Give it its own nights, or cut something else from a California 10-day itinerary. Joshua Tree is the winter alternative when these roads want chains. The state overview is the California travel guide.

South gate or north gate

If you have two full days and a normal car, enter Ash Mountain, sleep in Three Rivers or Wuksachi, do Sherman and Crystal Cave on day one, then Generals Highway to Grant Grove and Cedar Grove on day two, and exit toward Fresno. If you have one day and a long vehicle, skip 198 entirely: Big Stump, Grant Tree, a look at the canyon if the road is open, and don’t pretend you also “did Sherman.”

Confirm the live road table the morning you leave. The $35, the $100, and the 22-foot painted line are the parts that don’t care about your itinerary.
