Out and back hike from the Geronimo Trailhead in South Mountain park in Phoenix, Arizona.
The Geronimo trailhead is a bit tricky to find, but once you've found it, it is not difficult to follow the Geronimo trail. After skirting the edge of the nearby neighborhood, you'll walk along a boy scout obstacle course. After passing this, the trail climbs steadily. It's a bit of a rocky trail in places but we found it enjoyable. After about 1.1 miles of hiking, you'll reach a signed trail junction (JCT 1L on the map) stay left here. After 2.5 miles of hiking, you'll reach the ridgeline. At the top, if you go South, you'll hook up with the National trail. Go North instead (right) and walk the short way to some great views of the Phoenix area and South mountain. When ready, return the way you came. Keep an eye out for mountain bikers, as they like to zip down this trail.
