Overview / About

Located in southern Arizona, just outside Tucson, Saguaro National Park protects one of the most iconic landscapes of the American Southwest, the Sonoran Desert, home of the majestic saguaro cactus. These towering giants, some over 150 years old and 40 feet tall, define the desert skyline and give the park its name.

Established in 1933 and divided into two districts, the Rincon Mountain District (east) and the Tucson Mountain District (west) the park spans more than 91,000 acres. Despite its arid appearance, Saguaro is teeming with life, from desert tortoises and roadrunners to blooming cacti and vibrant sunsets.

This is the desert at its most dramatic and alive, a place where every cactus tells a story of survival.

Wildlife & Nature

  • Other notable plants include ocotillo, cholla, prickly pear, creosote bush, and mesquite.
  • In the Rincon Mountains, as elevation rises, you’ll find oak woodlands and pine forests, a rare desert-to-mountain transition.

Fauna:

  • Common desert dwellers include Gila monsters, kangaroo rats, javelinas, bobcats, and coyotes.
  • Birdlife is rich, Gambel’s quail, cactus wrens, Gila woodpeckers, and hawks fill the skies.
