From the Keystone Gulch Trailhead, head up the Keystone Gulch access road for about a mile and look for a bridge crossing the creek to your right. Cross the bridge to start out on the Aqueduct Trail. Follow the trail over some skinny bridges above the aqueduct with rock cliffs on the left and a drop off to the right.
Enjoy beautiful views of Buffalo and Red Mountains to the north through a few clearings, and eventually head around the corner to the south through what seems like the front yard of some large houses at the golf course. The trail soon ends at the Keystone Ranch Rd. You can continue on Soda Ridge Trail
to the left or turn around and go back the way you came.
