Yellowstone is an iconic wilderness area that sits mostly in Wyoming, with smaller sections extending into Montana and Idaho. It is best known for its geothermal features, wide open valleys, and abundant wildlife that draw millions of visitors each year.
The park spans several counties and is centered on the remains of a ancient supervolcano, making it both a dramatic landscape and a powerful natural laboratory.

Geographic Coordinates and Exact Location
Precise Latitude and Longitude Range
The core of Yellowstone sits roughly between 44° and 45° north latitude, and 110° and 111° west longitude. These coordinates place the park primarily in the northwest corner of Wyoming, far from dense urban centers but connected by major highways and regional airports.
Landscape Boundaries and Nearby Features
To the north, the park touches the border with Montana near Gardiner and Livingston. To the east, it meets the Chief Joseph Highway corridor, while the western boundary runs close to the Idaho line. The southern edge aligns closely with the town of Jackson and the Teton Range, creating a dramatic backdrop of mountains, geothermal basins, and pristine rivers.
Access Points and How to Reach Yellowstone
Major Highways Leading Into the Park
Five primary routes provide road access to Yellowstone. U.S. Route 212 approaches from the northeast through Livingston, U.S. Route 89 enters from the north near Gardiner, U.S. Route 191/287 brings visitors from the south through Jackson, and U.S. Route 20/26/89 combine from the west via Idaho. Interstate 90 offers the fastest connection to Bozeman, where travelers can switch to U.S. Route 287 for a scenic drive south into the park.
Airport Options and Ground Transportation
Most visitors arrive via Bozeman Yellowstone International Airport, which offers the broadest commercial service. Jackson Hole Airport is ideal for travelers aiming for the southern entrance, while smaller regional airfields support charter and general aviation needs. From these hubs, rental cars, shuttles, and guided tours connect visitors to trailheads, hot springs, and wildlife viewing areas across the park.
Seasonal Conditions and What They Mean for Travelers
Winter Access and Snow Management
From roughly mid-December through March, heavy snowfall closes most interior roads, limiting access to the southern loop via U.S. Route 20 and 287. Snowmobile and snowcoach tours become popular alternatives, offering guided travel through quiet geothermal basins and quiet valleys. Winter conditions require careful planning for vehicle preparation, permits, and flexible schedules.
Summer Crowds and Wildlife Activity
During the summer months, park roads open widely, and visitation peaks. Wildlife viewing remains strong in early morning and late evening, particularly in Lamar and Hayden Valleys where bison herds and predators are often active. Travelers should book accommodations and campgrounds well in advance and expect long lines at popular geothermal sites like Old Faithful and Grand Prismatic Spring.
