DescriptionPicacho Peak was often used as a landmark by early explorers. During the 17th century, dedicated Jesuit priest Father Kino mentioned Picacho Peak in records of his journeys into Arizona, and in 1775, the DeAnza Expeditions passed by the Peak. In 1846, the Mormon Battalion, on their way to California to fight in the war with Mexico, constructed a wagon road through Picacho Pass. The forty-niners traveled the same road on their way to California, and in 1858, mail and passengers traveled this route via the Butterfield Overland Stage. This route is now used by the Transcontinental Railroad.
The most significant Civil War battle in Arizona took place near Picacho Peak on April 15, 1862, when an advance detachment of Union forces from California attacked a Confederate scouting party. The battle lasted for 1-1/2 hours, and three Union soldiers were killed. Every March, "The Civil War in the Southwest" comes alive again as over two hundred re-enactors converge on Picacho Peak on foot and horseback. Also on display at the March reenactment are recreated military camps and living history demonstrations.
Picacho Peak State Park has several campgrounds and picnic areas. There are grills, a dump station, restrooms, and showers. It is located along I-10 at Exit 219 60 miles south of Phoenix, and 40 miles north of Tucson.
