Welcome to the iconic Yellowstone National Park, founded in 1872, making it the first national park in the world. With a population of roughly 81 (yes, you read that right), this town boasts geothermal wonders like Old Faithful, diverse wildlife including grizzly bears and wolves, and stunning natural beauty at every turn. Despite its small size, Yellowstone National Park has sister city relationships with Ngorongoro Conservation Area in Tanzania and Galápagos Islands in Ecuador, solidifying its global importance in conservation efforts.
