Refuge Quick Facts
The Imperial National Wildlife Refuge was established in February 14, 1941 and is 25,768 acres. It was established as a refuge and breeding area for migratory birds and other wildlife.
Beavertail Imperial National Wildlife Refuge protects wildlife habitat along 30 miles of the lower Colorado River in Arizona and California, including the last unchannelized section before the river enters Mexico.
The river and its associated backwater lakes and wetlands are a green oasis, contrasting with the surrounding desert mountains.
Refuge Highlights
Wetland wildlife is most abundant in winter, when ‘snowbirds’ such as cinnamon teal and northern pintail use the refuge. During the summer months, look for permanent residents such as great egrets and muskrat. In the desert, wildlife such as black-tailed jackrabbits and western whiptail lizards are plentiful. Watch at dawn and dusk for desert bighorn sheep and mule deer heading to the river for a drink.
Wilderness
More than 15,000 acres of Imperial National Wildlife Refuge is federally designated wilderness. Wilderness is protected to ensure that nature, not people, is the primary influence on this quiet, scenic place.
Forest in the Desert?
At one time, the banks of the Colorado River were lined with cottonwood and willow forests, sustained by the river’s natural periodic flooding. Animals depended on this green forest oasis for breeding, resting, feeding, and shade.
Woodcutting during the steamboat era, clearing for agriculture, wild fire, exotic plants like salt cedar, and use of dams for flood prevention have devastated cottonwood and willow stands along the lower Colorado River. Some animals that depend on these forests, such as the southwestern willow flycatcher, have become endangered.
Refuge staff are working with other agencies and organizations to plant cottonwood and willow trees. From the observation tower, look for patches of restored forest.
Ducks, geese, shorebirds, and other waterbirds flock to the lower Colorado River each year to spend the winter. Refuge staff and volunteers restore wetlands, protect backwater lakes, manage marsh units, and farm croplands to provide food and resting areas for these winter residents.
Things to do at the Refuge
The Visitor Center is open from 7:30 am to 4:00 pm, Monday through Friday. From November 15 to March 31, also open Saturdays and Sundays from 9:00 am to 4:00 pm. Enjoy the exhibits, native plant garden, and watch a wildlife video.
Red Cloud Mine Road
Follow this scenic drive through the Sonoran desert landscape to access the lookout points and the Painted Desert Trail. If you intend to drive further than the Painted Desert Trailhead, a 4-wheel drive vehicle is recommended. Check with the Visitor Center for road conditions.
Lookout Points
Mesquite, Ironwood, and Smoke Tree Points offer beautiful views of the Colorado River valley. Often, both desert and wetland wildlife may be seen. All of the lookout points can be reached by vehicle.
Painted Desert Trail
Walk this 1.3-mile self-guided trail for an opportunity to see desert plants and wildlife. The trail takes you through a rainbow of colors left by 30,000 year-old volcanic activity and features a panoramic view of the Colorado River valley.
Meers Point
Looking for a quiet place to canoe or fish? Meers Point has shaded tables, toilets, and a boat launch. The refuge surrounds one of the few remaining "wild" places on the Colorado River. This stretch is valued by boaters for its remote scenery.
For Your Safety
The desert can be dangerously hot and dry. Be sure to carry and drink plenty of water, use sunscreen, and wear light-colored clothing, including a hat. Watch out for stinging insects, venomous reptiles, and thorny plants. Avoid putting your hands and feet under rocks or into crevices and plants, and watch where you step or sit.
Help Protect the Refuge
Hiking, photography, and wildlife observation are permitted on the refuge, except within the waterfowl management units and staff residence area. Travel in wilderness areas is by foot or horseback only. Hunting and fishing are permitted, according to state regulations, in some areas. Please contact the Visitor Center for more information.
