Arizona is the state of the Grand Canyon, red sand and endless dunes, but the widespread saguaro cacti are truly the state icon. If you want to admire forests of these alien-like ancients, visit the Saguaro National Park near the beautiful town of Tucson, Arizona. The desert has plenty of birds, lizards, fish and other interesting varieties of animal life, but they are world famous for their iconic saguaro cacti. Driving towards acres of towering cacti stretching over the Tucson Mountains is an eerie, unsettling experience. The cacti can tower over 21 meters tall, with multiple long straight or crested branches reaching toward the heavens.
