Hike up Slate Mountain near Flagstaff, Arizona.
There used to be a fire lookout at the top of Slate Mountain. This lookout was removed and the road leading to it has been reclaimed by the forest, with only a trail to the top remaining. This is a great result for hikers like us.
From the parking area, follow the signed trail to Slate Mountain trail. The trail is easy to follow throughout its length. Another nice thing about this trail is that the forest is relatively thin here, so the views are mostly unobstructed. As you climb, you'll be treated to increasingly impressive views of the San Francisco peaks and Kendrick Mountain. Once you reach the top, you'll see why this was a good spot for a fire lookout, as your reward is an abundance of views. I tried to find any evidence of the fire lookout, but I was unable. They either did a really good job removing it or I didn't do as good a job searching for it as I thought.
When ready, return the way you came.
