Saguaro National Park is open year round, daily from sunrise to sunset, with peak visitation in March.
The saguaro has been described as the monarch of the Sonoran Desert, as a prickly horror, as the supreme symbol of the American Southwest, and as a plant with personality. It is renowned for the variety of odd, all-too-human shapes it assumes, shapes that inspire wild and fanciful imaginings. Giant saguaro cacti, unique to the Sonoran Desert, sometimes reach a height of 50 feet in this cactus forest, which covers the valley floor, rising into the Rincon and West Tucson mountains. Since 1933 this extraordinary giant cactus has been protected within Saguaro National Park. Preserved along with it are many other members of the Sonoran Desert community--other cacti, desert trees and shrubs, and animals. In lushness and variety of life the Sonoran Desert far surpasses all other North American deserts.
Most visitors enjoy the scenic drives, bird watching, photography, hiking, and participating in guided walks. There are many special programs throughout the cooler months. Check at a visitor center for a detailed list.
Numerous guided walks are offered at each visitor center. Published schedules of programs are available during the winter season. Special environmental education programs are frequently conducted for local school groups. Several Junior Ranger Programs are available.

The flowering season is dependent upon a complex set of environmental factors which include precipition, temperature, soil, elevation and extreme exposure. Combinations of these factors produce blooming at different times and locations.
Desert annual wildflowers are at their best in the spring, but may bloom at other times throughout the year. Winters that have plentiful rainfalls at regular intervals will produce spectacular displays that may occur only once a decade. These outstanding flowering shows generally last one or two weeks around the end of March to the beginning of April. At such times many areas of the desert are carpeted with flowers of all colors.
Mountain wildflowers also occur in a great variety of colors. However, blooming will occur later in the year because of cooler temperatures. Generally, wildflowers at higher elevations will bloom four to eight weeks later than those on the desert floor. Flowers on the mountain ridges with southern exposures will bloomfirst while deep facing canyons will flower last.
Not all desert plants require such specific environmental conditions to bloom. Many, such as flowering trees, cacti and some perennials have evolved special adaptations that allow them to bloom at the same time each year, regardless of the amount of winter rainfall. The mesquite tree has a deep root system which extends to groundwater. Some plants can store water for use during dry periods while others die, leaving their seeds to wait for favorable conditions.
