Approximate location — plotted from published sources, not a site visit, and not a guarantee of access.
Hereford Bridge Trailhead is a main public access on the San Pedro Riparian National Conservation Area south of Sierra Vista. Just east of the bridge over the San Pedro River, it leads into one of the most important lowland riparian birding corridors in the Southwest. The Bureau of Land Management manages the NCA for wildlife and non-motorized recreation along the river.
