9Yellowstone National Park, Wyoming, Montana, and Idaho
Yellowstone National Park, established in 1872 as the world’s first national park, is a land of dramatic landscapes and geothermal wonders. Spanning three states, this vast wilderness is home to an array of natural features that are unlike anything else in the world. Old Faithful, the park’s most famous geyser, erupts predictably every 90 minutes, shooting boiling water high into the air. The park is also home to the colorful Grand Prismatic Spring, the largest hot spring in the United States, with vibrant hues of blue, green, and orange. Yellowstone’s wildlife is equally impressive, with bison, elk, wolves, and grizzly bears roaming the park’s expansive valleys. From its volcanic activity to its dramatic canyons and waterfalls, Yellowstone is a park of endless beauty and fascination.
