The San Pedro River features some of the richest wildlife habitat in the Southwest. Here you'll find 82 species of mammals, dozens of different reptiles and amphibians, and nearly 350 species of birds. In addition, the river supports one of the largest cottonwood-willow forest canopies remaining in Arizona and is one of the last free-flowing rivers in the Southwest.

The interpretive river walks are usually 1.5 to 2 miles long over easy terrain, including sections where the trail is uneven and rough. They are slower paced than a hike and suitable for most adults and children. There is no charge for the walks.
