Prescott National Forest
The drive down a mountainous section of AZ 89A from Jerome to Prescott is gorgeous (if somewhat harrowing in bad weather), filled with twists and turns through Prescott National Forest. A scenic turnoff near Jerome provides one last vista and a place to apply chains during surprise snowstorms. There's camping, picnicking, and hiking at the crest of Mingus Mountain. If you're coming to Prescott from Phoenix, the route that crosses the Mogollon Rim, overlooking the Verde Valley, has nice views of rolling hills and is less precipitous.
