Stinking Springs, FR 191, runs through the Cibola National Forest from Highway 400 to the edge of the Navajo Nation, where it becomes County Road 48. The trail begins in the east as a well-graded forest road with numerous large pine-shaded campsites passing Prewitt Lake and a large open meadow. Moving west, the road deteriorates with deep ruts before plunging off the western side of the Zuni Mountains into Stinking Springs Canyon via a narrow rocky shelf road with one extremely tight switchback turn. The views in the descent are impressive. The lower canyon is tree-lined and lush.
