|Havasu National Wildlife Refuge stretches along the Colorado River for thirty miles from Lake Havasu City, Arizona, north to Needles, California. It consists of just over 37,500 acres of classic upland desert with the Colorado River running through it. As such it is important to all of the many different types of birds that migrate along this portion of the Pacific Flyway. A number of species nest here and a variety of mammals are found in the refuge as well. Moat visitors access the refuge by boat, but it is also possible to gain limited access at several points along the shoreline.
