About the Sonoran Desert
The Sonoran Desert is the greenest of North America’s deserts, thanks to two separate rainy seasons. It is the only place where the towering saguaro cactus grows wild, its arms a symbol of the American West. Roadrunners, Gila monsters and desert tortoises all make their home among its cacti.
Did you know?
A saguaro cactus can live for more than 150 years and grow taller than 12 metres.
