I live in El Portal, two thousand feet below the Valley floor in the Merced River canyon, and for twenty seasons I have watched the same thing happen every November. The park empties. The tour buses stop coming. The trailhead lots that required a 6 a.m. arrival in July sit half full at noon. And then, some night in late November or December, a storm comes through, the clouds pull apart the next morning, and Yosemite Valley is standing there under fresh snow with almost nobody looking at it. The people who plan around summer have quietly agreed to skip the best-looking months in the park. I have never fully understood it, and I have stopped trying to talk people out of it, because the emptiness is the point.
This is a practical guide to Yosemite in winter: what is actually open, how to drive in without drama, what there is to do, and the honest costs of the season. It is a different park from the one in the postcards, except on the mornings when it is exactly the park in the postcards, only white.
The most important fact of winter planning is a simple one: Yosemite Valley is open year-round. The Valley floor sits at about 4,000 feet, low enough that snow falls, sticks for a while, and usually melts back off the roads within days. Plowed roads reach Yosemite Valley, Wawona, Hetch Hetchy, and Badger Pass all winter. Lodging, food service, the visitor center, and the shuttle keep running. Winter does not close Yosemite. It closes the high country.
Tioga Road, the high crossing through Tuolumne Meadows, closes with the first serious snow, typically in November, and does not reopen until late May or later, depending on the snowpack. Glacier Point Road closes on roughly the same schedule beyond the Badger Pass turnoff. If your mental map of Yosemite includes Olmsted Point, Tenaya Lake, or the drive-up view from Glacier Point, subtract them from a winter trip. They are under snow, and the only way to reach them is on skis or snowshoes.
The Mariposa Grove splits the difference. The road up to the grove closes for the season, but the grove itself stays open. You walk, snowshoe, or ski the closed road, roughly two miles each way from the Welcome Plaza, and the reward is giant sequoias holding snow on their branches with a fraction of the summer crowd. Sequoias in snow are one of the sights the park does best and one of the least seen.
I am biased, because it is the road past my house, but the bias is earned: Highway 140 through the Merced River canyon is the lowest and most reliable winter approach to the park. It follows the river up from Mariposa at canyon-bottom elevations, which means it takes rain when the higher entrances are taking snow. Storms still close it occasionally, and chain control still reaches it, but on an average winter day it is the entrance with the least weather on it. The other approaches, Highway 41 from Oakhurst and Highway 120 from Groveland, both climb well over 5,000 feet before dropping to the Valley and carry chain control more often. The full entrance-by-entrance comparison is in the entrances guide; the winter summary is: take 140 if you can.
Chain control is the part of winter driving that surprises first-time visitors, so here it is plainly. When conditions warrant, Caltrans and the park post chain requirements at checkpoints, in three levels. R1 means chains are required unless you have snow tires. R2 means chains are required unless you have four-wheel or all-wheel drive with snow tires. R3 means chains on everything, no exceptions, and in practice roads usually just close before R3 is posted.
The detail that catches people: whenever chain control is in effect inside the park, you must carry chains even if your vehicle is exempt from putting them on. A 4WD truck with snow tires can drive through R2 without chains mounted, but the driver still needs a set in the vehicle, and rangers do check at the checkpoints. Rental-car agreements almost universally prohibit chains, which is a problem between you and the rental company, not one the checkpoint will solve for you. Chains can be bought or rented in the gateway towns, Mariposa, Oakhurst, Groveland, and shops along 140 will often rent a set and take it back on your way out. Practice putting them on once in a dry parking lot, not for the first time in a snowbank at night. The winter car kit covers the rest of what should be in the trunk.
The checkpoint does not care what your all-wheel-drive badge says. Carry the chains.
Badger Pass Ski Area, on the open lower stretch of Glacier Point Road, is one of the oldest ski areas in California, operating since the 1930s, and it has stayed deliberately small: a handful of lifts, a modest vertical, gentle terrain, a day lodge. Nobody flies in for it. That is its charm. It is a family-scaled hill where lessons are cheap by ski-industry standards, kids learn without being run over, and the lift line conversation is about the park rather than the snow report. If your measure of a ski area is terrain steepness, go to Tahoe. If your measure is teaching a seven-year-old to snowplow inside a national park, Badger is close to ideal.
Badger matters even if you never ride a lift, because it is the trailhead for the winter high country. The closed section of Glacier Point Road becomes a groomed ski track, and the marked winter routes into the Glacier Point backcountry all start from the Badger parking lot. Rentals for skis and snowshoes are available at the lodge. It is the one place in the park where winter has real infrastructure.
The signature winter day trip in Yosemite is Dewey Point. From Badger Pass you follow the groomed road, then a marked snow route through the forest to the Valley rim, and the trees open onto a straight-down view of the Valley with El Capitan across the void, all of it snowbound and nearly silent. It runs about seven miles round trip depending on the route variant, an honest half-day on snowshoes for a reasonably fit party. There is no summer version of this experience. In July, Dewey Point is a nice viewpoint. In February it feels like being let in on something.
For a gentler entry, the park offers ranger-led snowshoe walks from Badger Pass through the winter season, typically two hours through the woods near the ski area, with snowshoes provided for a small fee. They are unglamorous and quietly excellent, the ranger stopping to point out marten tracks and explain how a fir survives under ten feet of snow. Check the current Yosemite Guide or the conditions page for schedules before you drive up.
The Curry Village ice rink is the most improbable amenity in the park: an outdoor rink on the Valley floor where you skate loops while Half Dome stands overhead in winter light, with a fire pit at the edge for the between-sessions thaw. Skating has been happening at Curry Village for roughly a century, and it remains cheap, low-key, and better at dusk than at any other hour, when the granite goes pink and the rink lights come on. It is the rare Yosemite activity that works with small children, bad knees, and no planning.
Here is the case for winter that needs no infrastructure at all: clearing storms are the best photographic conditions Yosemite offers, and winter is when they happen. A storm breaks up over the Valley, fog tears off the walls, snow outlines every ledge on El Capitan, and for an hour or two the place looks the way it did in the photographs that made it famous. Residents watch the radar and drive up for the clearing, and you can do a modest version of the same thing: if the forecast shows a storm ending mid-morning, be at Tunnel View when it does. Where to stand and when is covered in the photography guide.
And February brings the park's strangest scheduled event. For about two weeks in the middle of the month, when the angle of sunset is right and the fall is running and the sky cooperates, Horsetail Fall on the east shoulder of El Capitan lights up orange at the last minute of the day and appears, briefly, to be on fire. The firefall now draws real crowds and a reservation system of its own, which makes it the exception to everything else in this article; the full logistics are in the Horsetail Fall guide.
Winter asks things of you. The days are short: the sun clears the Valley rim late and drops behind it early, and the deep sections of the floor hold shade, and therefore black ice, all day. The paths around Curry Village and the base of the falls glaze over and stay glazed. Traction cleats for your boots cost little and prevent the most common winter injury in the park, which is not an avalanche, it is a tourist slipping on a paved path. Valley inversions park cold air and fog on the floor for days at a time, so a gray, raw morning in the Valley is often a blue one at Badger Pass, a thousand-plus feet higher.
In exchange: the crowds are gone, genuinely gone, in a way no summer strategy can simulate. Lodging that books out months ahead in July has winter availability at winter prices, and the trade-offs between staying in the park and staying down the canyon are laid out in the lodging guide. You will stand at viewpoints alone. You will hear the Valley, which in summer you mostly cannot.
The waterfalls, mostly asleep since August, begin to come back in late winter as early melt and rain reach the Merced. By March, Yosemite Falls is a waterfall again rather than a stain, and the whole hydrological year described in the waterfalls guide starts over. Late winter also brings one of the park's oddest small phenomena: on the coldest early-spring mornings, Yosemite Creek can run with frazil ice, a slush of ice crystals that moves down the channel like slow lava and piles into banks of white. It is a niche thing to chase and a story for another article. Consider it the park's way of saying the quiet season is ending.
Come up 140 with chains in the trunk. Stay two nights in or near the Valley. Skate at dusk, snowshoe to Dewey Point or walk into the Mariposa Grove, and watch the weather for a clearing storm. If it is February, look at Horsetail Fall like everyone else, then notice that the other twenty-seven days of the month you have the place nearly to yourself.
Twenty seasons in, winter is still the version of this park I would defend first. That's the trip.
