Desert Biking
If you're feeling up to the challenge of two-wheel travel in the desert, hit the road with Ajo Mountain Drive, a 21-mile, one-way loop that serves as one of the main sightseeing routes within the monument. Little or no technical biking skills are required, but the length of the ride (not to mention the Arizona heat) does require a moderate level of physical fitness. The drive climbs gradually up and around the Diablo Mountains to an elevation of 2,600 feet, offering views of Mount Ajo, the highest peak in the range (4,808'), and Mexico's Cubabi Mountains. Allow at least three hours to complete this loop.

Desert Driving
One of Arizona's most scenic roads, Puerto Blanco Drive (53 miles) showcases the beauty of Organ Pipe Cactus National Monument. The route travels deep into unspoiled backcountry, across plains and through mountain foothills. Besides the varied plants of the Sonoran Desert, the drive passes close to old mines, springs, historic sites, and the surprising, tree-lined Quitobaquito Oasis. In addition, there are a number of side hikes ranging from short nature trails to lengthy, unmaintained routes. A small hill at mile 10 offers particularly fine views over the Valley of the Ajo, the mountains, and the road itself. At the south edge of the Puerto Blanco Mountains, a short spur road takes visitors to Senita Basin — the best place to see the monument's three major species of cacti (saguaro, organ pipe, and the rare senita) growing together. Get out of the car and take one of the trails that climb into the mountains towards other old mines. All of the road is unpaved but still passable without four-wheel-drive.
