About Alamo Canyon Primitive Campground
Overview
Alamo Canyon Campground sits nestled at the base of the Ajo mountains in Organ Pipe Cactus National Monument. This primitive campground provides scenic views of the surrounding mountains and Sonoran Desert, along with spectacular night sky viewing and peaceful quiet.
Recreation
Along with photography and birding, hiking is ideal here. There is a 0.9 mile one way trail that leads into Alamo Canyon from the campground. Beyond the campground there are miles of hiking trails laced around Organ Pipe Cactus National Monument, some easy, others more strenuous. Always carry water and snacks, and avoid hiking during the hottest parts of the day. Stop at the Kris Eggle Visitor Center for recommendations.
Facilities
Alamo Canyon Campground has four campsites with charcoal grills, picnic tables, a pit toilet, and trash cans. It is tent camping only; RVs, motorhomes, and trailers are not permitted. Wood fires and ground fires are not allowed. Generators are prohibited.
Natural Features
Organ Pipe Cactus National Monument exhibits an extraordinary collection of plants and animals of the Sonoran Desert. This is a showcase for creatures who have adapted themselves to the extreme temperatures, intense sunlight, and little rainfall that characterize this Southwest region. Thirty-one species of cacti have mastered the art of living in this place, including the park's namesake and the giant saguaro. Here, the life of the Sonoran Desert is protected and allowed to flourish under nearly ideal wilderness conditions. The monument is an outstanding natural preserve where one of the Earth's major ecosystems survives almost unspoiled.
