This section of the Sonoran Desert near the border between Arizona and Mexico features massive cacti, colorful birds and rock arches. An International Biosphere Reserve and a federally designated wilderness area, this park preserves the only large concentration of organ pipe cacti in the country, as well as hundreds of other native plant species, such as saguaro, cholla, mesquite and palo verde trees, and ocotillo. Hike on the park's nine scenic trails or take a drive on the 21-mile Ajo Mountain Drive to experience the vibrant desert landscape.
