Puerto Blanco Drive circles the colorful Puerto Blanco Mountains and passes through a startling variety of scenery. Around one corner you will find the desert oasis of Quitobaquito, while around another you'll find a true Sonoran Desert environment, with saguaros, organ pipe cacti and elephant trees.
As of March 1, 2004 the first five miles of the North Puerto Blanco Drive are open for two-way travel, allowing access to the Red Tanks trail head. The remainder of the road will be closed indefinitely.
South Puerto Blanco Drive and North Puerto Blanco (past the five-mile gate) are closed until further notice. The first five miles of North Puerto Blanco Drive has been newly reconstructed and is open in both directions, providing access to the new picnic area at the turn-around point by Pinkley Peak.
