 Park County is one of Wyoming's 23 counties. It is located in Northwest Wyoming, home of Cody, which was founded by one of America's greatest legends, Buffalo Bill Cody. Did you know Park County has not always been Park County? Historically, it was a part of Sweetwater County, which was one of the five counties defined following Wyoming statehood in 1890. What is Park County today was then a part of Fremont and later Bighorn counties. The Wyoming state legislature authorized the formation of Park County in February of 1909, and Cody was later designated as the county seat. What's in the name? Park County is comprised of federal, state, local, and private lands. The county is almost four and a half million acres, including a significant part of Yellowstone National Park. Yellowstone was established in 1872, and today is a designated world heritage site and biosphere reserve. So the next time you find yourself traveling through Park County, Wyoming, remember, you're not only in the home of an American legend, but you're in the county that is ground zero for preserving the world's natural resources.
