Saguaro National Park in Southern Arizona protects and preserves a giant saguaro cactus forest that stretches across the valley floor near the city of Tucson. In the spring, not only will you see America’s largest cacti that cover the beautiful desert landscape, but a rainbow of color in between. The blooming wildflowers include desert marigolds, Mexican gold poppy, and red penstemons, while many of the shrubs, trees, and cacti are in bloom, too, including the chollas, hedgehogs, and creosote bushes. There are also prehistoric petroglyphs to explore, historic sites, and wildlife viewing to enjoy. Watch for animals like coyotes, desert tortoises, and javelinas in the lower elevations and the Mexican spotted owl, deer, and black bear in the upper elevations of the park.
