Alto Coop Trail #619


***NOTICE: Box Culvert Trail 620 temporarily impassable under Iron Springs Rd by motorcycles, OHVs, and equestrians after monsoon rains in Doce Fire area***


Trail Description: Alto Coop Trail #619 traverses a sculptural landscape of igneous granite that time has eroded into the striking boulder formations typical of the Prescott area.  The trail stays mostly in thick chaparral composed of scrub oak and mountain mahogany.  Yucca and prickly pear cactus find purchase in exposed soils.  A closer look at these plants can reveal evidence of wildlife that is seldom seen along the trail.  Javelina forage on both these species, gnawing the edges off of leaves.  Scrub jays, particularly fond of pinyon pine, are usually heard before they are seen. 




This trail, used primarily by off-highway vehicles, ties into the network of motorized trails southwest of Granite Mountain.  The trail serves as a bridge between the Alto Pit OHV Recreation Site and Box Culvert Trail #620 and Tonto Trail #621.  Please note that Alto Pit is a fee area.  For more information, call the Bradshaw Ranger District at (928) 443-8000.

This trail is open to off-highway vehicles less than 50” in width and closed to horses.  Prepare for hot, dry conditions and meager shade during summer.
