Kofa NWR

If you enjoy an escape to the Desert Southwest during the winter months but hope to avoid the congestion of large cities and National Parks, consider a visit to Kofa National Wildlife Refuge, northeast of Yuma, Arizona. This extensive preserve (over 665,000 acres) was set aside in 1939 to protect habitat for desert bighorn sheep; more than 80% of the refuge is designated wilderness and it thus harbors some of the most pristine Sonoran Desert landscape in the U.S.

Stretching between the Kofa Mountains on the north to the Castle Dome Mountains in the south, this refuge is accessed by a network of graveled roads, most of which require four-wheel drive vehicles. However, the road to Palm Canyon, leading east from US 95 between Quartzite and Yuma, can be traversed by the family car and is perhaps the best means to explore this ecosystem; a short trail at its terminus leads to a stand of California fan palms and conditioned hikers can proceed on to higher terrain.

In addition to the fan palms, the only palms native to Arizona, Kofa NWR is known for its tremendous diversity of Sonoran Desert plants, including the Kofa mountain barberry. Of course, the refuge is also home to a spectacular variety of desert wildlife; joining the reclusive desert bighorn sheep are mountain lions, coyotes, mule deer, kangaroo rats, five species of rattlesnake, a diverse collection of lizards and the usual mix of Sonoran desert birds. Named for the abandoned King of Arizona gold mine, this wilderness also harbors remnants of past mining and ranching activity; since it was used for military training during WWII, it may contain unexploded ordinance and visitors are cautioned not to handle such materials.
