This is 3,100 mile long trail which extends across the United States from Canada to Mexico. It passes through the states of Idaho, Wyoming, Utah and Arizona. Throughout much of its length it is actually a corridor of trails which parallel each other and accommodates a wide variety of both motorized and nonmortorized users.

On some sections of the trail these uses are separated and on other sections, they share the same pathway. The 800 mile portion of the Great Western Trail within the state of Arizona will be primarily used as a motorized trail as the existing Arizona Trail, which also runs the length of the state, is designed soley for nonmotorized use.

The 30 miles of the trail on the North Kaibab Ranger District overlays a number of existing dirt roads. The route runs from sagebrush-pinyon-juniper country to Ponderosa pine and spruce-fir forest and back down to pinyon-juniper and sagebrush lands.
