Cibola NWR is located in the floodplain of the lower Colorado River and surrounded by a fringe of desert ridges and washes. The refuge encompasses both the historic Colorado River channel as well as a channelized portion constructed in the late 1960's. Along with these main waterbodies, several important backwaters are home to many wildlife species that reside in this portion of the Sonoran Desert. Because of the river's life sustaining water, wildlife here survive in an environment that reaches 120 degrees in the summer and receives an average of only 2 inches of rain per year. We invite you to visit and enjoy the many wildlife-oriented activities the refuge has to offer and enjoy the scenic beauty of this oasis in the desert.
