I walked daily miles in the banks of the San Pedro River. The beauty, tranquility and atmosphere of this place cannot be described with any pictures. Surrounded by birds, other wildlife, and bathed in the Arizona sun.  It was amazing. I would call it the Eight Wonder of the World.

San Pedro River is originating about 10 miles south of the international border south of Sierra Vista, Arizona, in Sonora, Mexico. Within Arizona, the river flows 140 miles (230 km) north to its confluence with the Gila River, at Winkelman, Arizona. It is the last major, free-flowing undammed river in the American Southwest, it is of major ecological importance as it hosts two-thirds of the avian diversity in the United States, including 100 species of breeding birds and 300 species of migrating birds,
