Sequoia road seasons
These are the park's general seasonal rules, not guaranteed dates. NPS describes Cedar Grove access variously as the fourth Friday in April, late April or early May, and May through early to mid-November.
| Road | Vehicle season or access rule | Destinations & limits |
|---|---|---|
Generals Highway (south) | Normally year-round | Ash Mountain to Lodgepole; storm closures and chain controls possible. Vehicle-length advisory at 22 feet. |
Generals Highway (north) | Normally spring to early January; winter closure varies | Lodgepole to Grant Grove. Unplowed from the Friday after January 1 to the third Friday in March. |
Kings Canyon: Hwy 180 | Generally fourth Friday in April to mid-November | Kings Canyon route to Cedar Grove; weather can shift access into May. Hume Lake has separate year-round access. |
Mineral King Road | Generally Wednesday before Memorial Day to last Wednesday in October | Narrow, curving and partly unpaved. RVs and trailers not recommended. |
Crystal Cave Road | Generally mid-May to late September, tour days only | Road access depends on cave tours; gated each night. |
Moro Rock-Crescent Meadow Road | Generally late May until snow makes it impassable | During summer shuttle service, private-car restrictions apply on weekends and holidays. |
South Fork Road | Normally year-round | Separate Three Rivers approach; unpaved past the entrance and slippery in rain or snow. |
Winter access
Plan around the normal winter road pattern, then check official conditions before driving.
Connecting the two parks
The Generals Highway north of Lodgepole is unplowed from the Friday after January 1 to the third Friday in March and often closes for snow. Gates are north of Wuksachi Lodge and near Highway 180 by Grant Grove. A winter trip to both parks may require returning to the foothills. NPS identifies Highway 245 west of the parks as an alternative. Check road status.
Cedar Grove and Hume Lake
The Kings Canyon road to Cedar Grove is seasonal. Caltrans gates Highway 180 just beyond Hume Lake Road, 6 miles northeast of Grant Grove, because freezing conditions bring rockfall. Hume Lake remains reachable by its year-round approach. NPS route descriptions.
Wolverton and Moro Rock
After snow makes Wolverton Road impassable, its normal plowing days are Friday through Sunday, Wednesdays and holidays for snowplay access. Moro Rock-Crescent Meadow Road is not cleared of snow and becomes a skiing or snowshoeing route. NPS winter road access. See Sequoia in winter for trip planning.
Before you drive
Match your vehicle and route to the road-specific rules before setting out.
Generals Highway south
The Ash Mountain route has narrow hairpin turns between Hospital Rock and Giant Forest.
- NPS advises against vehicles 22 feet and over between Potwisha Campground and Giant Forest Museum.
- For longer vehicles, consider the Big Stump Entrance on Highway 180.
- Use designated pullouts.
Generals Highway north
The Lodgepole to Grant Grove link needs its own winter access check.
- Do not assume the two parks connect by road in winter.
- Snow can also interrupt spring travel between Wuksachi Lodge and Montecito Sequoia Lodge.
Highway 180 to Cedar Grove
This Kings Canyon route has a winter gate beyond the Hume Lake junction.
- The general opening is late April or early May, weather permitting.
- Much of the route is in Sequoia National Forest; check Caltrans for the state highway.
Mineral King Road
A separate, narrow and curving road reaches Mineral King.
- Upper sections are partly unpaved.
- RVs and trailers are not recommended and are prohibited in Mineral King campgrounds.
- Check project-specific delays before travelling.
Crystal Cave Road
Drive here only on days cave tours operate.
- Gated nightly.
- Some sections are rough after fire and storm damage; drive slowly.
- Cave tours require advance reservations, with no walk-up tours.
Moro Rock-Crescent Meadow Road
Summer weekends and holidays use the free shuttle while it operates.
- Private vehicles are restricted from morning through late afternoon on those days.
- Park at Giant Forest Museum or another shuttle stop.
- No drinking water along the road.
Backpackers with a wilderness permit may access this trailhead 24 hours a day, including when it is closed to normal traffic.
South Fork Road
The road branches from Highway 198 in Three Rivers, about 6 miles south of the park entrance.
- Unpaved past the park entrance.
- Rough for some vehicles and slippery in rainy or snowy weather.
- Check campground and trailhead access separately before driving to the end.
Chains, fuel and side roads
Carry chains or cables from fall through spring; snow can bring chain controls at any time of year. Fill up before entering either park.
Chain-control zones
Every vehicle, including four-wheel and all-wheel drive, must carry properly fitting chains or cables whenever any chain requirement applies. The speed limit is 25 mph in chain controls. Check the road recording and posted signs because requirements can change several times a day. Vehicles without the required traction equipment can be turned away. NPS winter driving rules.
Fuel and charging
NPS lists no gas stations or electric-vehicle charging stations inside either park. Fuel in the neighboring national forest is at Hume Lake year-round and Stony Creek Resort in summer. NPS fuel guidance.
Other narrow approaches
Panoramic Point Road in Kings Canyon prohibits RVs and trailers. North Fork Road has narrow blind curves and deep, wide ruts near the trailhead; low-clearance vehicles are not recommended. Check NPS road conditions for Middle Fork Road and other access restrictions.
Outside the parks
Caltrans and (800) 427-7623 cover roads outside the parks. For Sequoia National Forest roads such as Hume Lake Road, call the Hume Lake Ranger District at (559) 338-2251. NPS road contacts.
Road access and trip timing
Normal road seasons and monthly park visitation answer different questions. Neither predicts access on a particular day.
Monthly context
In historical NPS monthly park visits, March averages 29%, April averages 42%, May averages 62%, September averages 63%, October averages 48%, November averages 31% of July, the busiest month. These are park visits, not vehicle or road counts. Entrance queues can be long on Fridays, Saturdays and holidays from Memorial Day to Labor Day. NPS has recorded waits over an hour on the busiest days. See the month-by-month guide for the full comparison. The October guide covers that month in detail.
Questions about Sequoia road closures
Quick answers to the practical questions below.
Is Sequoia National Park open today?
The normal season does not establish today's access. The Generals Highway from Ash Mountain to Lodgepole normally provides year-round access, with closures possible during and after storms. Mineral King, Crystal Cave and Highway 180 to Cedar Grove in Kings Canyon have seasonal access. Call (559) 565-3341, press 1 then 1, and read NPS current conditions before driving.
Can you drive from Sequoia to Kings Canyon in winter?
Sometimes. The Generals Highway between Lodgepole and Grant Grove is unplowed and often closed from the Friday after January 1 to the third Friday in March. When it's closed, you may have to drive back down to the foothills, and NPS says Highway 245, west of the parks, is often used instead. Check the NPS road conditions page before you plan both parks in one winter day.
Do you need chains in Sequoia National Park?
Carry them from late fall through spring. Chains may be required any time it snows, and whenever a chain requirement is in effect, every vehicle in the zone, including four-wheel and all-wheel drive, must carry chains or cables. The park posts an alert whenever chains are required, and vehicles without traction devices may be turned away from some roads.
Does a government shutdown close Sequoia's roads?
The September 2025 NPS contingency plan said roads, lookouts, trails and open-air memorials would generally remain accessible during a funding lapse, but regular road and trail condition updates would stop. It also required closing an area when access created a safety, health or resource-protection issue, including weather and road hazards. That plan does not guarantee access during a future shutdown; check official instructions before travelling.

- Official guidance
- NPS and the relevant operators. The linked official pages support the access, facilities and rules described here. Confirm details before traveling.

Topic sources and data details
Normal road seasons, the Generals Highway winter-plowing regime, vehicle advisories, shuttle restrictions and fuel guidance come from NPS road information. Road-specific access and contact details come from NPS road conditions. Cedar Grove wording differs across NPS pages; the table preserves the general April rule with its May qualification.
Chain rules come from NPS winter driving guidance. Temporary projects and closures are checked through NPS road construction and current conditions. Normal seasons are approximate, not a schedule for a particular year.
The shutdown FAQ describes the September 2025 NPS contingency plan as historical policy, not a guarantee of future access.
Map lines use existing OpenStreetMap geometry routed by OSRM under ODbL. They show road locations, not live closure gates. Monthly park-visit comparisons retain the existing NPS visitation dataset and describe park attendance, not road traffic.
