Some 350 bird species (many endangered), more than 80 mammal species and more than 40 species of reptiles and amphibians have been recorded along the 40-mile stretch of the San Pedro River within this 89-sq-mile conservation area. This vital riparian ecosystem has also become a corridor for drug smuggling from Mexico – suspicious activity should be reported.
The visitor center, in the 1930s San Pedro House, is 6 miles east of Sierra Vista on Hwy 90. From here you can access several hiking trails.
