The Havasu Wilderness now contains a total of 17,801 acres and is managed by the Fish & Wildlife Service's Havasu National Wildlife Refuge.

Arizona contains approximately 14,606 acres. California contains approximately 3,195 acres. In 1994 the Havasu Wilderness became part of the now over 110 million acre National Wilderness Preservation System.

Established in 1941, Havasu National Wildlife Refuge stretches along the Colorado River for 30 miles between Needles, California and Lake Havasu City, Arizona, with most of the refuge situated in Arizona. Approximately one-third of the refuge--all of it in Arizona--was designated Wilderness in 1990. California got into the act in 1994, adding almost everything north of Blankenship Bend on the Colorado River. This area shares its western border with the large Chemehuevi Mountains Wilderness.

The Wilderness is rich in wildlife including quail, geese, ducks, grebes, cranes, rails, herons, egrets, falcons, eagles, bighorn sheep, coyotes, porcupines, foxes, and bobcats. Here you may see the endangered desert tortoise and the poisonous Gila monster. Exemplary desert hiking through creosote, ocotillo, blue-green paloverde, and pockets of saguaro promises solitude.
