Organ Pipe Cactus National Monument

Anyone seeking solitude beneath big, blue, open skies will love the crowdless scenery of this stunning national park. Home to 28 species of cacti and a wide variety of fauna, it has two campgrounds and plenty of hiking trails and scenic drives. The wildflowers and milder temperatures during spring make this an attractive time to visit, while summers can be insufferably hot, bringing monsoon rains between July and September.
