The Badlands Wilderness now contains a total of 64,144 acres and is managed by the National Park Service. All of the wilderness is in the state of South Dakota.
Public land becomes wilderness through legislation passed by the United States Congress in the form of public laws. For the Badlands Wilderness, this process began in 1976 when 64,250 acres were designated by Public Law 94-567.
The Badlands Wilderness is part of the 106 million acre National Wilderness Preservation System.
