The Friends of the San Pedro River will host interpretive walks on the first and third Saturdays of each month. The walks will depart from the San Pedro House, 9800 E. Highway 90, east of Sierra Vista at the river. The San Pedro River features some of the richest wildlife habitats in the United States. Here you’ll find 82 species of mammals, dozens of reptiles and amphibians, and nearly 350 species of birds. The river has been designated one of the Last Great Places by the Nature Conservancy. Dress appropriately for the weather, bring drinking water, wear trail shoes, a hat, and use sun protection. All walks are free. For more information, call (520) 508-4445 or email fspr@sanpedroriver.org.
