Sentinels of the Sonoran Desert
Established in 1994, Saguaro National Park protects 91,716 acres of the Sonoran Desert in two districts flanking Tucson. The park showcases the nation's largest cacti, the iconic saguaro, which can grow to over 50 feet tall and live for more than 150 years.
Beyond the majestic saguaros, the park features ancient petroglyphs, diverse wildlife, and six distinct biotic communities ranging from desert scrubland to pine forests. The park's unique sky island mountains rise dramatically from the desert floor, creating varied ecosystems that support remarkable biodiversity.
