The New Water Mountains Wilderness (24,600 acres) in Arizona, is managed by the Bureau of Land Management. In 1990, the New Water 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. How to follow the seven standard Leave No Trace principles differs in different parts of the country (desert vs. Rocky Mountains). Click on any of the principles listed below to learn more about how they apply. Motorized equipment and equipment used for mechanical transport are generally prohibited on all federal lands designated as wilderness. This includes the use of motor vehicles (including OHVs), motorboats, bicycles, hang gliders, wagons, carts, portage wheels, and the landing of aircraft including helicopters Contact the agency for more information about regulations. 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.

The New Water Mountains Wilderness Area is located east of Quartzsite, just south of I-10 and just north of the Kofa National Wildlife Refuge in La Paz county.

The western boundary of the Wilderness can be accessed from I-10 at the Gold Nugget Road exit (#26). Taking the exit for State Route 60 (#31) and then turning right onto Ramsey Mine Road gives access to the northern boundary.

Due to infrequent maintenance and the wide range of road conditions that you might encounter, it is strongly recommended that high-clearance, four-wheel-drive vehicles are used for access to the Wilderness boundary.
