San Pedro Riparian
National Conservation Area

san pedro houseDescription
The San Pedro Riparian National Conservation Area (NCA) contains nearly 57,000 acres of public land in Cochise County, Arizona, between the international border and St. David, Arizona. The riparian area, where some 40 miles of the upper San Pedro River meanders, was designated by Congress as a Riparian National Conservation Area on November 18, 1988. The primary purpose for the special designation is to protect and enhance the desert riparian ecosystem, a rare remnant of what was once an extensive network of similar riparian systems throughout the American Southwest. One of the most important riparian areas in the United States, the San Pedro River runs through the Chihuahuan Desert and the Sonoran Desert in southeastern Arizona. The river’s stretch is home to more than 80 species of mammals, two native species and several introduced species of fish, more than 40 species of amphibians and reptiles, and 100 species of breeding birds. It also provides invaluable habitat for 250 species of migrant and wintering birds and contains archaeological sites representing the remains of human occupation from 13,000 years ago.

The San Pedro Riparian National Conservation Area is located 6 miles east of Sierra Vista, Arizona. From Tucson, take Interstate 10 east 40 miles to State Highway 90. Follow the highway south through Huachuca City to Fry Boulevard in Sierra Vista, AZ. Follow this street for six miles east until you reach the San Pedro House.  The San Pedro Riparian National Conservation Area can also be accessed via Highway 80, near St. David; Highway 82 to Fairbank; Charleston Road to Millville Historic Townsite; Hereford Road to Hereford Bridge; and Highway 92 to Palominas.

Visitor Activities 
The area provides opportunities for wildlife viewing including birdwatching, picnicking, primitive camping, pre-historic and historic site visiting, hunting, hiking, fishing, biking, horseback riding, guided hikes, interpretive site visitation, and weekend children’s programs.  Parking, interpretive kiosks and trailheads are located at Fairbank, Murry Springs, San Pedro House, Land Corral, Terrenate, Millville and Hereford Bridge.  Parking and trailheads are also available at Hereford Road, Charleston Road, Palominas, Terrenate, Escapule and Lehner.  The Friends of the San Pedro lead regularly scheduled guided walks:

  • Every Saturday at 8:00 a.m. - Guided Nature and History Walks (Starting from San Pedro House)
  • 2nd Wednesdays and 4th Saturdays at 7:00 a.m. - Bird Walks (Starting from San Pedro House)
Special Features
The national conservation area features the intact remains of the Spanish Presidio Santa Cruz de Terrenante, a Spanish fortress marking the northern extension of New Spain into the New World. The Murray Springs Clovis Site is a significant archaeological resource that contains evidence of the earliest known people to inhabit North America. An interpretive trail leads visitors to the site. The area also features the ruins of the old mining town of Fairbank. The San Pedro House, a 1930’s-era converted ranch house, serves as a bookstore and visitor center.
