Giant Cactus Forests on Both Sides of Tucson

Saguaro National Park protects forests of giant saguaro cactus on both sides of Tucson, Arizona, in the Rincon Mountain and Tucson Mountain districts. Saguaros grow naturally only in the Sonoran Desert. The area became a national monument in 1933 and a national park in 1994.

Saguaros grow very slowly, often taking 50 to 75 years to sprout their first arms, and they can live over 150 years. Their white blossoms, Arizona's state wildflower, open in late spring and are pollinated by bats at night and birds and bees by day. Gila woodpeckers carve nest holes that later shelter other birds.

The Tohono O'odham people traditionally harvest saguaro fruit in early summer, marking the start of a new year. At Signal Hill, visitors can see petroglyphs carved by the ancient Hohokam people. Scenic drives like the Cactus Forest Loop wind through the desert.
