AskPatty's Guide to 12 Great National Parks: Yellowstone National Park, Idaho, Montana, and Wyoming
On March 1, 1872, Congress established Yellowstone National Park in the Territories of Montana and Wyoming "as a public park or pleasuring-ground for the benefit and enjoyment of the people," and placed it "under exclusive control of the Secretary of the Interior." The world's very first national park remains the showpiece of the National Park Service, and was visited by 4.1 million people in 2015.
The vast reserve -- which covers 2.2 million acres in Wyoming, Idaho, and Montana -- offers alpine lakes and thermal hotsprings, craggy peaks, explosive geysers, and deep forests. Its wealth of wild animals include bison, bears, sheep, moose, and wolves. Yogi Bear and his pal BooBoo immortalized the park in animation, as "Jellystone" park was their favorite location for stealing "Picanic baskets."
