Welcome to the Southwestern Region

The Southwestern Region covers more than 20.6 million acres, boasting thousands of recreation opportunities spread across six national forests in Arizona, five national forests and a national grassland in New Mexico, and one national grassland each in Oklahoma and the Texas panhandle.

The elevation ranges from 1,600 feet above sea level and an annual rainfall of 8 inches in Arizona's lower Sonoran Desert to 13,171-foot high Wheeler Peak and over 35 inches of precipitation a year in northern New Mexico.
