The park was created in 1937 as a way to preserve a representative area of the Sonoran Desert. The new monument was part of a movement in the National Parks to protect not just scenic wonders but also the ecological wonders of the country. Over 75 years later, Organ Pipe Cactus is now one of the best preserved examples of the Sonoran Desert wilderness. Within the monument, signs of human use are also preserved and protected. The monument is the site of culture and history that reflect long, widespread and diverse use by American Indian, Mexican, and European groups. The intesection of these of these three cultures is significant archeologically, geographically, and internationally. 

When to Visit: warm days (60s F) and chilly nights (40s F) are common during the late fall to early spring, with occasional rains. Most visitation occurs between December and March. Consistent winter rains will produce gorgeous spring wildflowers. Early summer days are hot and dry with temperatures in the 100's and humidity below 10%. Late summer monsoons bring fantastic lighting and furious thunderstorms. Temperatures drop to 90s, however the humidity increases. During the summertime plan on getting up early and spend the afternoons in the shade.
