Yellowstone invented the idea. Signed into being in 1872, it was the first national park anywhere on Earth, sprawled across the high corner where Wyoming meets Montana and Idaho. It sits on the lid of an active supervolcano, and you feel it everywhere: the ground steams, springs glow colors that shouldn't be real, and more than 500 geysers — over half the world's total — keep their own restless schedule.
But the thermal show is only half the draw. The Lamar and Hayden valleys hold the best wildlife watching in the Lower 48 — bison herds that stop traffic, wolves at first light, grizzlies working the far slopes. Between them run long, gorgeous miles where every pullout is its own reason to stop.
It's also bigger than first-timers expect. The Grand Loop alone is a 142-mile figure-eight, and the distances between basins are part of the experience, not an obstacle to it. Give Yellowstone more days than you think you need — this is a park to settle into, not to check off.
Yellowstone is a driving park before it is anything else. The sights are strung along a loop road big enough that crossing between two of them eats an afternoon, five entrances each drop you into a different corner of it, and for half the year most of the tarmac is under snow. Which entrance you use and which month you come decide the trip far more than any hike does.
The one road kept open to ordinary cars all winter, running from Gardiner through Mammoth and on to Cooke City by way of Tower Junction. Everything else shuts. If you want Yellowstone in February, this fifty-mile strip is the whole park you get, and you drive it out and back. Through 2026 the Gardner River High Bridge just southeast of Mammoth is down to one lane around the clock with waits of up to fifteen minutes, and rigs over 8 ft 6 wide, 75 ft long or 80,000 lb cannot cross it at all.
The West Entrance is the closest to Old Faithful — 30 miles, about an hour — and takes more traffic than any other. It opens first in spring, on 17 April in 2026, along with the roads to Madison, Norris, Canyon and Old Faithful.
The long climb in from Cody, 118 miles to Old Faithful and a good three hours. It opens later than the west side — 1 May in 2026 — because the pass holds snow, and it is the natural approach if you are coming across Wyoming rather than down from Montana.
In from Cooke City, with the Beartooth Highway climbing behind it to almost 11,000 feet. The Beartooth opened 22 May in 2026 and closes 12 October — the shortest season of any approach, and the best road of the lot. The Chief Joseph Scenic Byway alongside it is open all year from the Cody end; only its last nine miles into Cooke City close to wheeled vehicles in winter.
In 2026: west side 17 April, East Entrance 1 May, South Entrance 8 May, all closing 31 October; Canyon to Tower Fall runs 22 May to 12 October only
Two stacked loops joined in the middle, and the road that connects almost everything with a name. Distances between the big sights run to fifty miles and speeds are low, so treat any single day as one half of the eight rather than the whole thing. Old Faithful to Mammoth alone is 52 miles and takes the better part of two hours before you stop for anything.
TipBison stop traffic completely and without warning, and they do it daily. Build slack into every leg — the delay is not an accident, it is the normal operating condition of this road.
Opens 22 May and closes 12 October in 2026 — the shortest season inside the park
The section over the shoulder of Mount Washburn, and the first to close and last to open. Plenty of trips get planned around a loop that is not actually joined up yet in mid-May, which is the single most common Yellowstone routing mistake.
Open to cars year-round — the only road in the park that is
East from Tower Junction through the broad glacial valley where the wolves and the bison are. It stays plowed all winter, which makes it the only drive-yourself Yellowstone available between November and April, and arguably the best one at any time of year. In winter it is also an out-and-back: US-212 shuts east of Cooke City, so you turn round and drive the same fifty miles home.
TipDawn and dusk, every time, with binoculars rather than a long lens. Pull fully off the road — the shoulder here is where most of the park’s traffic incidents happen.
The largest hot spring in the country, ringed in bands of orange, gold, and impossible blue — a rainbow you can see from the air.
Insider tipFrom the boardwalk you mostly see steam. For the famous overhead view, take the easy half-mile climb to the Grand Prismatic Overlook off the Fairy Falls Trail, and go near midday when the sun has burned off the haze.
Plan a trip to this spot →The best wildlife watching in the Lower 48 — wolves at dawn, grizzlies on the slopes, and bison herds that bring traffic to a stop.
Insider tipGo at first or last light, and match the valley to the animal: Lamar in the northeast for wolves and big herds, Hayden in the center for grizzlies in spring and early summer. Look for the cluster of spotting scopes.
Plan a trip to this spot →One square mile holds roughly a quarter of all the geysers on Earth. Old Faithful is just the opening act.
Insider tipCheck the ranger prediction board — it forecasts five geysers, not only the famous one — then walk the boardwalk loop out to Morning Glory Pool. Most of the crowd turns back long before the far end.
Plan a trip to this spot →The Lower Falls drop 308 feet — nearly twice Niagara — into a gorge of yellow and rose-colored rock that gave the park its name.
Insider tipArtist Point on the South Rim is the classic head-on view, best in morning light. For the river's raw power, hike the steep Brink of the Lower Falls trail down to the very lip where it goes over.
Plan a trip to this spot →Terraced 'frozen waterfalls' of white-and-orange travertine — a wholly different kind of thermal feature, and one that's alive and rearranging itself constantly.
Insider tipWalk the Lower Terrace boardwalks where the active springs flow, then drive the one-way Upper Terrace loop to save your legs. A terrace that ran dry last year may be the gushing one now.
Plan a trip to this spot →Norris is the hottest, most volatile basin and home to Steamboat, the world's tallest active geyser; West Thumb sets its hot springs right on the shore of Yellowstone Lake.
Insider tipDon't bank on a Steamboat eruption — they come days to years apart. Catch West Thumb at golden hour instead, when low light on the lake makes the pools glow and the crowds thin out.
Plan a trip to this spot →Yellowstone's weather is really a story about elevation. A July afternoon can be shirtsleeves and 80°F down at Mammoth in the northern lowlands while it's barely clearing 70°F — and threatening snow — up at the lake. Both ends of the park run cold at the edges of the season, so pack layers in any month.
Five gates, but only one road stays open to cars all winter — the northern run from Gardiner through Mammoth and Lamar Valley to Cooke City. The rest close to wheeled vehicles from early November until April or May. In between, from about 15 December to mid-March, the interior belongs to snowcoaches and snowmobiles, and those have to be commercially guided — you cannot simply drive your own sled in.
Mammoth Hot Springs, the Roosevelt Arch, and Lamar Valley wildlife. The only entrance you can drive in winter.
The busiest gate and the shortest run to Old Faithful and the geyser basins, with the most services of any gateway town.
West Thumb, Grant Village, and the southern lakeshore — and the obvious choice if you're pairing Yellowstone with Grand Teton. Note you drive through Grand Teton to reach it, and that park charges its own separate entrance fee.
Fishing Bridge and the lake's east shore, by way of scenic Sylvan Pass, which can close on short notice for weather.
Doorstep of Lamar Valley and the spectacular Beartooth Highway. Tiny towns — fuel up and stock up before you arrive.
Three ways to sleep at Yellowstone, and all of them reward planning ahead — the marquee rooms and the best campsites are some of the hardest reservations in the park system.
Nine lodging areas, all run by the concessioner Yellowstone National Park Lodges, from the cathedral-like Old Faithful Inn and the National Historic Landmark Lake Yellowstone Hotel — the oldest hotel still operating in the park — to simple cabins at Roosevelt and Canyon. Two, the Old Faithful Snow Lodge and the Mammoth Hot Springs Hotel, stay open through winter.
Booking tipRooms open roughly thirteen months ahead, and the Old Faithful Inn's historic 'Old House' rooms can vanish the same day. Book the moment your window opens, then keep watching for cancellations as your dates get close — they do turn up.
Eleven campgrounds and over 2,000 sites, ten of them open in 2026 — Pebble Creek is still shut for repairs after the 2022 floods. Five book through Yellowstone National Park Lodges, including Fishing Bridge RV Park, the only site in the park with water, sewer and electric hookups; the other six book on Recreation.gov.
Booking tipAlmost nothing is first-come anymore. Every site must be reserved ahead, on a rolling window that opens exactly six months before your arrival date — the one exception is Mammoth, which goes first-come from mid-October to mid-April. Tiny Slough Creek in Lamar Valley (16 sites, wolves howling at night) is the toughest ticket in the park. Car camping outside a designated site is banned everywhere, pullouts included.
Can't get a room inside? Base in a gateway: West Yellowstone for the most services and the quickest shot at the geysers, Gardiner for year-round access and the northern range, Cody for a real Western town, or Jackson for polish and an airport — at the cost of a longer drive in through Grand Teton.
Booking tipGardiner is the one gateway that still works in winter. Jackson looks close on a map and is three hours from Old Faithful, most of it inside two parks at 45 mph.
Do I need a reservation to get in?
No. Yellowstone has no timed-entry or vehicle-reservation system — pay the fee or show a pass and drive in. Its neighbors differ, so check each one separately: Rocky Mountain still requires a timed-entry permit from late May to mid-October, while Arches and Glacier both dropped theirs for 2026. The Yellowstone pass is $35 per vehicle for seven days ($30 motorcycle, $20 per person on foot or bike, under 16 free), and a Yellowstone annual pass is $70. Unlike some parks, the entrance stations still take cash. An America the Beautiful pass covers every national park for a year — $80 for U.S. residents, $250 for non-residents, who otherwise pay an added $100 per person aged 16 and over. One thing that catches people: coming in from Jackson through the South Entrance means passing through Grand Teton, and that is a second park with a second fee.
How many days do I need?
Give it at least three, and four or five to do it justice. The Grand Loop is a 142-mile figure-eight, and wildlife jams and full lots stretch every drive — this is not a one-day park.
How close can I get to the animals?
Stay 100 yards from bears, wolves and cougars, and 25 yards from everything else, bison and elk included. Bison injure more visitors here than any other animal and can outrun you three to one. Carry bear spray and keep it reachable — not buried in the trunk.
Will my phone work?
Mostly no. Cell service is spotty even near the developed areas and nonexistent across most of the park. Download your maps offline and plan to be unplugged — honestly, half the magic.
Where do I get gas and food?
Stations and general stores cluster at the developed areas — Old Faithful, Canyon, Grant Village, Mammoth, Fishing Bridge, and Tower-Roosevelt. Fill up when you can; the distances between them are long.
When do the roads open?
On a staggered schedule through spring. In 2026 the west side went first on 17 April, the East Entrance and Sylvan Pass on 1 May, the South Entrance and Craig Pass on 8 May, and Dunraven Pass last on 22 May. Most of it closes 31 October; Dunraven and the Beartooth go on 12 October. Only the Gardiner-to-Cooke City road through the northern range stays plowed all winter; the rest is oversnow travel from about 15 December to mid-March. Dates shift with the snow, so check the park's road status before you go.
Pick your vehicle, line up the stops on the way in and out, and carry the whole route in your pocket.
