The Three Sisters Wilderness now contains a total of 286,708 acres and is managed by the U.S. Forest Service. All of the wilderness is in the state of Oregon.
Public land becomes wilderness through legislation passed by the United States Congress in the form of public laws. For the Three Sisters Wilderness, this process began in 1964 when 196,708 acres were designated by Public Law 88-577. The following public laws also affect the Three Sisters Wilderness: 95-237, 98-328.
The Three Sisters Wilderness is part of the 106 million acre National Wilderness Preservation System. This System of wild lands contributes significantly to the ecological, economic, and social health of our country. Wilderness provides clean air and water, a shelter for endangered species, sacred places for indigenous peoples, a living laboratory for research, and a classroom for exploring personal values while experiencing risk, reward, and self-reliance. In wilderness, you can enjoy challenging recreational activities like hiking, backpacking, climbing, kayaking, canoeing, rafting, horse packing, bird watching, stargazing, and extraordinary opportunities for solitude. In an age of "...increasing population, accompanied by expanding settlement and growing mechanization," you play an important role in helping to "secure for the American people of present and future generations the benefits of an enduring resource of wilderness" as called for by the Congress of the United States through the Wilderness Act of 1964.
