Desert National Wildlife Refuge, 16001 Corn Creek Rd., encompasses more than 1.5 million acres and is home to hundreds of animal species, though many are nocturnal. Spotting bighorn sheep is a highlight. The visitor center has exhibits and also shows screenings of a film about the area. Camping and hunting opportunities are available.
Note: Phone ahead for road conditions in the refuge, and be aware of local weather as flash floods are a concern. High-clearance vehicles with four-wheel drive are recommended.
