The Williams Ranger District is on the Coconino Plateau and encircles the City of Williams, Arizona. It is one of three districts within the Kaibab National Forest.
The Williams Ranger District is 550,411 acres in size. It contains headwater tributaries of two main watersheds: the Verde and Colorado Rivers. It has no perennial streams and only a few reliable springs.
The district is cut east and west by Interstate Highway 40. State Highway 64 to the south rim of the Grand Canyon extends to the north. US Highway 180 from Flagstaff to state Highway 64 passes through the northern edge of the district, providing a second route to the Grand Canyon.
Elevations on the district range from 5,500 feet in the southwest to 10,418 feet on Kendrick Mountain near the northeast boundary. Much of the terrain is relatively level except for numerous small knolls, a few mountains, and the escarpment (Mogollon Rim) that cuts diagonally across the southwest section of the forest. The average elevation is approximately 7,000 feet.
