"This is an easy loop through the southern Sonoran Desert in Organ Pipe Cactus National Monument, starting from the Senita Basin Spur Road. Senita Basin is named after the rare Senita cactus, also known as old man cactus. Senita resembles the monument’s namesake organ pipe cactus, but it is distinguished by its beardlike growth of long gray needles at the tips of the branches. The Senita Basin Trail does a loop around the basin snuggled between the low hills of the Puerto Blanco Mountains, first heading east along the base of the hills. The trail then runs north across numerous small washes and ridges, then turns west and southwest to return to the trailhead."
