Denver to Yellowstone National Park is roughly 560 miles and 8 to 9 hours of driving. Most people reach the South Entrance via I-25 north to Cheyenne, I-80 west to Rock Springs, then US-191 and US-189 north through Jackson and Grand Teton. It's a long haul for one day, and splitting it over two is the smarter move.
The map estimate is optimistic. Google shows around 8 hours, but with gas, food, a wildlife jam in Grand Teton, and the slow last stretch into Yellowstone, plan on a roughly 10-hour travel day if you push it in one go. Below is the route I actually use, where to break it, and which entrance saves you time.
How far is Yellowstone from Denver?
It depends which of Yellowstone's five entrances you aim for:
- South Entrance (via Jackson): ~560 miles, 8.5-9 hours. The most scenic and the one most Denver travelers use because it runs you straight through Grand Teton.
- East Entrance (via Cody): ~600-620 miles, 9.5-10 hours. Longer, but Cody is a fun cowboy-town overnight.
- Northeast Entrance (Beartooth Highway, via Red Lodge): ~680 miles, 11+ hours. Spectacular, but only worth it if Beartooth itself is your goal.
For most people leaving Denver, the South Entrance through Jackson Hole is the right call. This guide focuses on that route.
The route: Denver to Yellowstone's South Entrance
There's no single highway; you stitch together interstates and two-lane US roads. The standard route:
- Denver to Cheyenne: I-25 North, ~100 miles, ~1.5 hours.
- Cheyenne to Rock Springs: I-80 West across southern Wyoming, ~250 miles, 3.5-4 hours. This is the high-plains, windy, monotonous part. Settle in.
- Rock Springs to Jackson: US-191 North through Pinedale and along the Wind River front, ~175 miles, ~3 hours. The scenery turns on here.
- Jackson to South Entrance: US-89/191/26 north through Grand Teton National Park, ~55-60 miles, 1.5-2 hours with stops.
An alternate route skips far-west I-80: take I-25 north to Casper, then WY-220 and US-26 west to Dubois, and climb over Togwotee Pass (9,655 ft) into Jackson Hole. It's similar in total time (~9 hours) but more scenic and avoids the I-80 grind. The catch: Togwotee Pass gets serious snow, so it's a bad idea roughly October through April unless conditions are clear. I take the I-80/Rock Springs route in shoulder seasons and the Casper/Dubois route in high summer.
Can you drive Denver to Yellowstone in one day?
Yes, but it's a brutal day. Leave Denver at 6 AM and you can reach the South Entrance by mid-afternoon, then drive another hour-plus to Old Faithful or Grant Village inside the park. The problem is you arrive exhausted, and Grand Teton, one of the best parts of the drive, blurs past your window.
My recommendation: make it two days. Drive Denver to Jackson on day one (about 7 hours), sleep in or near Jackson, then enter Yellowstone fresh the next morning. You'll see Grand Teton properly instead of speeding through it at 5 PM.
Where to stop and break the drive
- Cheyenne, WY (~1.5 hrs in): Good first gas and coffee stop. Cheyenne Frontier Days (rodeo) runs in late July, fun, but it clogs the town.
- Laramie, WY: College town just off I-80, decent lunch options.
- Rock Springs / Green River: Last reliable full services before the two-lane stretch north. Fill up here, gas thins out on US-191.
- Pinedale, WY: Gateway to the Wind River Range, a real mountain town and a good overnight if you want to break the trip outdoors and dodge Jackson's prices.
- Jackson, WY: The natural overnight. Touristy and expensive, but the antler arches on the town square, good food, and immediate Grand Teton access make it worth it.
The Grand Teton stretch: don't blow past it
Between Jackson and Yellowstone's South Entrance you drive the full length of Grand Teton National Park, and your Yellowstone entrance pass covers it (the same $35-per-vehicle, 7-day pass is valid for both parks). Quick stops worth making:
- Jenny Lake: Iconic Teton reflection. With 2-3 hours, the boat shuttle across the lake plus the short hike to Hidden Falls and Inspiration Point (roughly 2 miles round-trip from the boat dock, ~400-500 ft of gain) is the best quick payoff in the park.
- Schwabacher Landing & Oxbow Bend: The classic Teton-reflection-in-the-Snake-River pullouts. Best at sunrise.
- Colter Bay: Last gas, food, and visitor center before you enter Yellowstone.

What's open when: seasons on this route
- May 8 to October 31, 2026: the Park Service's dates for the South Entrance road to West Thumb, the road this route uses. The East Entrance road over Sylvan Pass runs May 1 to October 31, 2026. This is the window for the full drive.
- Early November to late April: most of Yellowstone's roads close to regular cars. Only the road from the North Entrance (Gardiner) through Tower Junction to the Northeast Entrance and Cooke City stays open to vehicles year-round. In winter the main loops are reachable only by guided snowcoach or snowmobile. The South Entrance typically reopens to cars in early-to-mid May.
- Shoulder (May & October): Roads can open or close on short notice for snow. Check the NPS Yellowstone road status page and Wyoming's 511 service the morning you drive.
If you're set on a winter trip, head for the year-round North Entrance (Gardiner, MT) instead. The Denver-to-South-Entrance route effectively doesn't work November through April.
Fees, gas, and practical notes
- Entrance fee: $35 per private vehicle, valid 7 days for both Yellowstone and Grand Teton. The $80 America the Beautiful annual pass pays off if you're hitting other parks too.
- Gas: Top off in Rock Springs/Green River and again in Jackson. Stations are sparse and pricey on US-191 and inside the parks.
- Cell service: Patchy from Rock Springs north and nonexistent in much of Yellowstone. Download offline maps before Pinedale.
- Wildlife: Bison and elk cause sudden traffic jams in both parks. Build in buffer time and never assume the last 60 miles will be quick.
- Wind: I-80 across Wyoming gets brutal crosswinds, and high-profile vehicle warnings are common. If you're towing or in an RV, check WYDOT 511 for closures.
Common mistakes
- Trusting the 8-hour estimate. With stops and park traffic it's closer to a 10-hour day. Plan accordingly or split it.
- Driving Togwotee Pass in shoulder season without checking conditions. It closes for snow; the Rock Springs route is the safer bet outside summer.
- Booking the first night deep inside Yellowstone. Arrive late and you'll be driving park roads in the dark dodging wildlife. Sleep in Jackson or near the South Entrance and enter in daylight.
- Skipping reservations. Yellowstone and Jackson lodging books out months ahead for summer. Don't wing it June through August.
Pair this drive with our Rocky Mountain National Park itinerary if you're starting your Colorado trip first. Plenty of travelers do RMNP, then point the car north to Yellowstone.
Turning It Into a Road Trip
Denver to Yellowstone works as a straight there-and-back, but the corridor sets up a bigger loop if you have the days. Three stops make the most sense:
- Rocky Mountain National Park, before you leave Colorado. About 65 miles and 1.5 hours from Denver via Estes Park. It is a detour off the I-25 and Casper routes north, not on the way, so give it its own day rather than trying to see it on the drive out.
- Grand Teton National Park, already built into the route. Everyone driving to Yellowstone’s South Entrance passes through it, but most people treat it as scenery out the window. Stop for a night at Jackson or Colter Bay and it becomes a real second park instead of a backdrop.
- Cody and the Beartooth Highway, on the way out. Leave Yellowstone through the East Entrance instead of retracing the drive in, and you pick up Cody, the Buffalo Bill Center of the West, and the option of the Beartooth Highway to Red Lodge if it is open (late May to mid October).
None of this changes the core drive time from the sections above, it just uses the same roads to turn one long haul into a multi park trip instead of a single destination.
Denver to Yellowstone National Park: Drive, Route & Stops FAQs
About 560 miles and 8.5-9 hours of driving to Yellowstone's South Entrance via I-25, I-80, and US-191 through Jackson. The East Entrance via Cody is farther (~600-620 miles, 9.5-10 hours).
In summer, I-25 to Casper then US-26 over Togwotee Pass (9,655 ft) to Jackson is the most scenic. In shoulder seasons, take I-25 to Cheyenne, I-80 west to Rock Springs, then US-191 north, which avoids the snow-prone pass. Both funnel through Grand Teton to Yellowstone's South Entrance.
Yes, but it's about a 10-hour day with stops and park traffic. Leaving Denver by 6 AM gets you to the South Entrance by mid-afternoon. Most travelers split the drive with an overnight in Jackson or Pinedale to see Grand Teton properly.
Plan 8 to 9 hours of pure driving, and realistically around 10 hours of total travel once you add gas, food, and slow stretches through Grand Teton. The last 100 miles are the slowest because of scenery stops and wildlife.
No. The South Entrance road closes to regular vehicles after October 31 (the 2026 date) and reopens in May, and most of Yellowstone's interior roads are closed to cars from early November to late April. For a winter trip, use the year-round North Entrance at Gardiner, Montana instead.
Cheyenne and Laramie early on, Rock Springs and Pinedale for fuel and the Wind River Range, then Jackson and all of Grand Teton National Park, including Jenny Lake and Oxbow Bend, which your Yellowstone pass already covers.
Yes, and a lot of Colorado-based travelers do. Rocky Mountain National Park is about 65 miles and 1.5 hours northwest of Denver via Estes Park, in the opposite direction from the I-25 or Casper routes north, so add it as a detour before you leave Colorado rather than trying to fold it into the same driving day.
At least five: one to reach Jackson, one to explore Grand Teton properly instead of driving through it, and three inside Yellowstone. Add a day at the start for Rocky Mountain National Park and a day at the end if you are driving all the way back to Denver rather than flying out.
