Bureau of Land Management, Arizona.
The Eagletail Mountains Wilderness (97,880 acres) in Arizona is managed by the Bureau of Land Management. In 1990, the Dos Cabezas Mountains Wilderness became part of the now over 109 million acre National Wilderness Preservation System established by the Wilderness Act of 1964. In wilderness, you can enjoy challenging recreational activities and extraordinary opportunities for solitude. Please follow the regulations in place for this area, and use Leave No Trace techniques when visiting to ensure protection of its unique natural and experiential qualities. Some lands around and within the wilderness are not federally administered. Please respect the property rights of the owners and do not cross or use these lands without their permission. Carry an ample supply of water with you since many areas have inadequate or unpurified water sources.
The Eagletail Mountains Wilderness is located 75 miles west of Phoenix just south of Interstate 10. It covers portions of Maricopa, La Paz, and Yuma counties.
