The San Pedro River Valley (Hereford, Sierra Vista) is formed by the Huachuca Mountains to the West, and the Mule Mountains to the east. The San Pedro River flows North out of Mexico and provides a greenway habitat for a wide variety of birds, butterflies, reptiles and mammals. Bisbee's old mining town is relaxing and entertaining. Good restaurants are available as well as unique saloons and music venues. The area is perfect for road tours with comfortable lodging at several top notch B&Bs at the end of the day.
