What State Is Yellowstone National Park In?

The majority of Yellowstone National Park is found in Wyoming. A small portion of the park (approximately 3%) is located in Montana and a sliver of the park (1%) is located in Idaho. Yellowstone was the first national park and it was established in 1872 by President Ulysses S. Grant. It is located over a supervolcano that powers the park’s geothermal features, including geysers and hot springs. 

America’s first national park is celebrated for the several geysers and springs, abundant wildlife, and Lake Yellowstone (the largest high elevation lake in North America). The park is so large that its entirety cannot be experienced in one day, or even one week for most people. Paved roads (maintained by the National Park Service) lead to most of the main attractions but hiking trails allow visitors to explore the rest of the park.
