Hereford Bridge Trail
hikingequestrianwildlife watching
The Hereford Bridge Trail is a portion of the long-distance San Pedro Trail offering visitors a diverse experience while traveling adjacent to the San Pedro River and into the San Pedro Riparian National Conservation Area. A delight to the senses, the diversity of birds, vegetation, and landscape features, will make this trip a journey worth savoring. Adjacent to the grasslands, the Fremont cottonwood-Goodding willow riparian forest is the most extensive riparian ecosystem remaining in the southwest. The BLM has protected this riparian habitat and the wildlife communities that thrive here, along with enhancing the opportunities for recreation, cultural interpretation, and education.
It is possible to hike from the Hereford Bridge all the way to the San Pedro House which is about ten miles along the river. A loop hike is possible by walking the old road bed north to Hunter Wash, then east to the river and back south back to Hereford Bridge. The total distance of the loop is about eight miles.
The Hereford Bridge Trail is located within the San Pedro Riparian National Conservation Area, approximately 6 miles west of Sierra Vista, Arizona. 
From Sierra Vista, travel south on Highway 92 for 5 miles. Turn left onto East Hereford Road and travel east for approximately 9 miles until you arrive at the Hereford Bridge parking area.
Visitor Activities 
Hiking, horseback riding, wildlife viewing, and bird watching.
