Organ Pipe Cactus protects a large piece of the Sonoran Desert along the Mexican border, where the organ pipe cactus grows wild in the US. Scenic drives like the Ajo Mountain Drive, hiking trails and a campground let you explore cactus forests and rugged mountains. Summer is dangerously hot, so visit in the cooler months and carry lots of water.
