General Layout and Geography—How Big Is Yellowstone National Park?

To understand how big Yellowstone National Park is, let’s talk numbers. Yellowstone National Park is 3,472 square miles—that’s 8,991 square kilometers or 2,221,766 acres. It also spans three states: Wyoming (96%), Montana (3%), and Idaho (1%).

Five Entrances and Gateway Communities

Because of its vastness, Yellowstone offers five main entrances to park goers.

  1. North Entrance: Located in Gardiner, Montana, this is the only entrance open year-round. It’s the best option for exploring Mammoth Hot Springs.
  2. Northeast Entrance: Near Cooke City, Montana, this entrance is known for its scenic drive through Lamar Valley. Visitors can expect to see wildlife up close—from wolves to bears to bison.
  3. East Entrance: Close to Cody, Wyoming, this entrance leads to the park’s picturesque East Entrance Road and Yellowstone Lake.
  4. West Entrance: Located in West Yellowstone, Montana, this entrance is open from mid April through the end of October. This is the most popular entrance during summer.
  5. South Entrance: Adjacent to Grand Teton National Park, visitors from Jackson Hole, Wyoming, will find themselves closest to the South Entrance.

Closest Major Cities

Consider traveling via these three main cities, which are relatively close to Yellowstone:

  • Bozeman, Montana: Roughly 90 miles north of the park, Bozeman is a popular base for Yellowstone visitors.
  • Salt Lake City, Utah: About 320 miles to the southwest, Salt Lake City serves as another critical starting point for your Yellowstone adventure.
  • Denver, Colorado: Approximately 500 miles southeast of Yellowstone, Denver is a central hub for travelers heading to the park.

Major Landscapes and Zones

Yellowstone’s diverse landscape includes various zones, each with unique features:

  • Geothermal Areas: These areas are home to the park’s famous geysers, hot springs, and fumaroles. Old Faithful and the Grand Prismatic Spring are must-see highlights.
  • Lamar Valley: Lamar Valley is known for its abundant wildlife, including bison, wolves, and grizzly bears.
  • Yellowstone Lake: North America’s largest high-altitude lake offers stunning views and recreational opportunities.
  • Grand Canyon of the Yellowstone: This dramatic canyon features breathtaking waterfalls and colorful rock formations.

Historical and Cultural Boundaries

Archeologists can trace humans in Yellowstone at least 11,000 years ago through sites, trails, and oral histories. Various Native American tribes inhabited the land before President Grant declared Yellowstone the first National Park in 1872. Grant’s decision to preserve Yellowstone’s scenery, wildlife, and cultural heritage continues to shape the visitor experience today.

Wildlife and Remote Zones

Yellowstone National Park showcases some of North America’s most diverse wildlife. Experience wild gray wolves in the Northern Range and elk in Mammoth. Based on when you visit (and to ensure you see certain species), schedule a summer or winter wildlife safari.

The park also includes remote zones, such as the backcountry areas and the wilderness of the Bechler region. These less-visited areas offer solitude and opportunities for backcountry hiking and exploration.

  • Thorofare Region: Over 31 miles from the nearest park road, the Thorofare Ranger Station is a popular destination for backcountry hikers. Be forewarned: you can only access this 2,600-square-mile area via foot or horseback, and you won’t find cell service here.
  • Teton Wilderness: Located within Bridger-Teton National Forest and part of the Greater Yellowstone Ecosystem, the Teton Wilderness is the most remote location in the contiguous United States.
  • Idaho “Zone of Death”: Tucked in a remote and rugged area of Idaho, the “zone of death” is a 50-square-mile section of Yellowstone National Park, where no one lives as of the 2020 census. Why the macabre name? Apparently, as a result of a reported loophole in the US Constitution, a person may be able to theoretically avoid conviction for any major crime here, even murder.
