Two National Treasures, One Epic Journey
If you’re mapping out your trip through the Northern Rockies, it’s natural to want to visit both Yellowstone and Grand Teton National Parks. These iconic destinations sit side by side, offering vastly different landscapes within a few hours’ drive. West Yellowstone serves as the most popular entrance to Yellowstone and makes a great home base for exploring the surrounding region. But how far is it from there to Grand Teton National Park?
The answer: approximately 125 to 140 miles, depending on your route. Most visitors can expect to drive about 2.5 to 3 hours to reach the northern edge of Grand Teton from West Yellowstone, not including stops or seasonal road conditions. Here’s how to plan that leg of your journey.
The Most Common Route: Through Yellowstone National Park
The most direct and scenic route from West Yellowstone to Grand Teton is by driving south through Yellowstone National Park. You’ll start at the West Entrance of Yellowstone and pass through some of the park’s most iconic features on your way south.
Approximate Distance: 125 miles
Estimated Drive Time: 2.5 to 3.5 hours (longer during summer or due to wildlife traffic)
Route Overview:
- Enter Yellowstone via the West Entrance in West Yellowstone, Montana.
- Drive east toward Madison Junction.
- Continue south toward Old Faithful or Lake Yellowstone (both are worth a stop).
- Pass through the South Entrance of Yellowstone.
- Enter Grand Teton National Park shortly after exiting Yellowstone.
- Follow Highway 191 south toward Jackson Lake and the rest of the Tetons.
This drive offers spectacular scenery, including rivers, geysers, bison herds, and alpine forests. If time allows, consider building in extra hours or even a day to enjoy attractions like:
- Fountain Paint Pot
- Grand Prismatic Spring
- Old Faithful
- Yellowstone Lake
- Lewis Falls
Keep in mind that you’ll need park entrance passes for both Yellowstone and Grand Teton, although a combined pass or America the Beautiful annual pass will cover both.
Alternate Route: Skipping Yellowstone
If you are traveling during winter or want to avoid traffic within Yellowstone, there is an alternate route that skips Yellowstone entirely. This is helpful when the southern roads in Yellowstone are closed due to snow, which is often the case between November and May.
Approximate Distance: 150 miles
Estimated Drive Time: 3 to 4 hours
Route Overview:
- From West Yellowstone, head west on US-20 to Ashton, Idaho.
- Take Idaho State Highway 32 south to Tetonia.
- Continue on Idaho State Highway 33 to Driggs and over Teton Pass.
- Enter Jackson, Wyoming.
- Drive north on US-191/89 to enter Grand Teton National Park.
This route trades national park scenery for a quiet, rural drive through farmland and mountain passes. Teton Pass is steep and often snow-covered in winter, so always check road conditions before traveling. While not as awe-inspiring as the park route, it still offers beautiful views of the western Teton range and is more efficient during off-season months.
Seasonal Considerations
Summer Travel (May to October):
This is the best time to travel between the two parks. All roads are usually open, and wildlife is active. Expect delays due to traffic or bison crossing, especially near Madison Junction or Hayden Valley. Allow extra time if you’re sightseeing.
Winter Travel (November to April):
Many of Yellowstone’s interior roads, including the South Entrance to Grand Teton, are closed to vehicles. You’ll need to take the alternate route through Idaho and over Teton Pass. Make sure your vehicle is equipped for winter driving and always check the forecast.
Can You Visit Both Parks in One Day?
Technically, yes. It’s possible to leave West Yellowstone early in the morning, drive south through Yellowstone, visit parts of Grand Teton, and return the same day. However, this would make for a very long and rushed day, especially if you want to stop and enjoy the sights.
A better plan is to stay overnight near Jackson or within Grand Teton National Park, giving yourself time to hike, take photos, or enjoy Jenny Lake and Signal Mountain. This also avoids driving at dusk, when wildlife are more active and visibility is reduced.
Where to Stay in West Yellowstone
To make this dual-park adventure work smoothly, start with a comfortable base. Grizzly RV Park & Cabins in West Yellowstone offers modern amenities, full hookups, and easy access to the Yellowstone West Entrance.

The convenience of staying right in town also means you can fuel up, grab groceries, or enjoy a good meal before hitting the road.
Scenic Stops Along the Way
If you’re in no rush, break up your drive between the parks with some memorable stops:
- Kepler Cascades – A quick stop with a powerful waterfall near Old Faithful.
- West Thumb Geyser Basin – A lakeside thermal area with quiet boardwalks and amazing views.
- Jackson Lake Overlook – Your first glimpse of the Tetons as you enter the park from the north.
- Oxbow Bend – One of the best photo spots in the park, with Mount Moran reflected in the Snake River.
These highlights make the drive part of the adventure, not just a connection between two parks.
Final Thoughts
West Yellowstone is about 125 to 140 miles from the Grand Tetons, depending on your route and season. The drive offers unforgettable scenery and easy access to two of America’s greatest national parks. Whether you take the scenic route through Yellowstone or the alternate route over Teton Pass, you’ll be treated to mountain views, wildlife, and small-town charm along the way.
