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.
I've driven this corridor several times running trips, and the honest truth is 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
- Roughly mid-May to early October: Yellowstone's South Entrance and interior roads are open to cars. Togwotee Pass is clear. This is the window for the full drive. (In 2026 the South Entrance opened May 8.)
- Early November to late April: Yellowstone's interior roads close to regular cars. Only the road from the North Entrance (Gardiner) to 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.
