The Bill Williams River meets the Colorado River just north of Parker Dam in west Arizona, after flowing for many miles through a deep, sheer-walled canyon surrounded by deserts and mountains. The lower end of the ravine is wide, filled with grasses and marshland, and the whole river corridor is home to a great variety of birds, plants and animals. Access is via a dirt road forking off AZ 95, 22 miles south of Lake Havasu City. Description | Photographs |
