Bill Williams Mountain is a high mountain peak at an elevation of 2.822m (9,259ft) above the sea level, located in Coconino County, in the north-central part of the U.S. state of Arizona. It's one of the highest mountain roads of Arizona.
Located south of Williams, within the Kaibab National Forest, the road to the summit is totally unpaved. It’s called Forest Road 111. The road is well maintained but steep. It’s usually impassable in winters. Reasonable high clearance is needed for most dry conditions. 4-wheel drive is probably not needed. The summit hosts a manned lookout tower and numerous communications equipment. It is named for Old Bill Williams, a scout, guide, and mountain man, who lived in the 1800s.
Expect a trail pretty steep. Starting from Perkinsville Road (County Road 73), the ascent is 10.78km (6.7 miles) long. Over this distance the elevation gain is 604 meters. The average gradient is 5.60%. Visitors should be prepared for high altitude conditions. Summertime temperatures average 70 degrees but can drop as low as 30 degrees at night or during the frequent summer afternoon thunderstorms. High winds frequently occur and thunderstorms always are a concern.
