Yellowstone National Park

National Park in Yellowstone National Park

America's iconic first national park, Yellowstone is home to over 60% of the world’s geysers – natural hot springs that periodically erupt in towering explosions of boiling water and steam. And while these astounding phenomena and their neighboring technicolor hot springs and bubbling mud pits draw in the crowds (over 4 million people each year), the surrounding canyons, mountains and forests are no less impressive, teeming with elk, bison, grizzly bears and wolves.
