Yellowstone: The World's First National Park

• A River Through Golden Rocks

  The park gets its name from the Yellowstone River, which in turn was named for the bright mustard-colored canyon walls it flows through.

• Lush, Steaming, Vibrant

  From the lush valleys to the rocky canyons to the steaming geyser basins to the peaceful lakes, Yellowstone's terrain is varied and vibrant.

• More Than Old Faithful

  Yellowstone is home to more than half the world's geysers and an exceptional concentration of geothermal energy.

• The 'Serengeti of North America'

  Yellowstone has the largest concentration of mammals in the contiguous United States including a high number of large predators.
