Yellowstone National Park

Founded in 1872 as the worlds first national park, Yellowstone spans 8,983 sq km across Wyoming, Idaho, and Montana, sitting atop a supervolcano with over 10,000 geothermal features including Old Faithful. The park contains more than half of Earth geysers and shelters the largest free-roaming bison herd in North America alongside wolves, grizzly bears, and wolverines. Around 4.5 million visitors make the journey each year to witness this unparalleled convergence of geology and wildlife.
