Box Culvert Trail #620

***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: Box Culvert Trail #620 traverses a sculptural landscape of igneous granite that time has eroded into the striking boulder formations typical of the Prescott area. The trail stays in open chaparral broken occasionally by pinyon pine and juniper, ideal habitat for scrub jays, towhees, and a number of other bird species.


This trail is used primarily by off-highway vehicles, and ties into the network of motorized trails southwest of Granite Mountain. This moderately technical trail meets up with Alto Coop Trail #619, before continuing on to Dosie Pit Road. This trail approaches the Alto Pit OHV Recreation Site, which 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. Prepare for hot, dry conditions and meager shade during summer.
