Hike to the fire lookout tower on Spruce Mountain via the Isabella trail near Prescott, Arizona.
From the small parking area, follow the brown trail sign marking TR377 (Isabella Trail). This well worn trail is easy to follow and is pleasantly shaded by pine and spruce. We spotted a few mule deer during the first mile of this hike as it climbs gently up the slope. After a little over a mile of hiking, you'll reach the signed trail junction (JCT_1R on the map). Stay right here to continue on towards Spruce Mountain. After another 0.1 miles, you'll pass a sign marking a helispot. Continue on the trail as views peek out from the trees.
You'll reach the easily spotted fire lookout tower after 3.2 miles of hiking. Even if you're not allowed up, there are great unobstructed views to be enjoyed here, with Granite mountain to the North West, the Mazatzal range to the East, and the town of Prescott to the North.
When ready, return the way you came.
