Yellowstone National Park is America’s first and foremost National Park.  Established in 1872 by the United States Congress for the preservation of its many wonders and for the enjoyment of the people. Yellowstone National Park – is located in the northwest corner of Wyoming, and includes small areas of Montana and Idaho as well. In addition to its superb Rocky Mountain scenery, the park is one of the world’s principal wildlife preserves. It’s also the site of America’s greatest concentration of geysers and hot springs, which form a visible and spectacular link with the primeval forces of the Earth’s creation. Yellowstone is also the oldest national park in the country. In fact, the original idea of setting aside natural resources like Yellowstone began here when some of the territory’s first explorers began a unique campaign to preserve the beauty of these lands for generations to follow. Here more than two million acres of a high mountain-ringed plateau have been set aside for permanent protection as a natural preserve. It’s been called America’s finest and most diverse vacationland.

 Yellowstone is a treasure that inspires awe in travelers from around the world, boasting more geysers than anywhere else on the globe. Yellowstone in its early days was known simply as “Wonderland.” It is the destination of a lifetime for all ages. Yellowstone National Park and the larger Yellowstone region feature numerous hotel and other lodging facilities. Lodging inside Yellowstone is highly desirable but limited.
