Hike to the top of Humboldt mountain near Cave Creek, Arizona.
This hike is not really along a trail, but instead up a seldom used road in poor condition. You could drive it if you had a good vehicle (or it would make a good, if steep, bike ride) but it makes a pleasant walk as well.
Park anywhere you can find a good pullout along either FR24 or FR562. Start walking up the paved road towards the easily spotted white FAA radar(looks like a big white ball). You'll walk fast, as the road is in good shape for walking but poor shape for driving. You may need to share the road briefly with a car, but for the most part, this road gets very little vehicle traffic. The scenery is high desert, with a few cacti, but mostly sparse grasses.
As you climb, you'll get more impressive views of the area. At the top, you'll get very good views of Horseshoe lake and the Verde River valley. The FAA radar station is interesting to view close up and there is also a fire lookout and some cellular towers here.
When ready, return the way you came.
