This is a four mile loop. I will also describe two possible ways that you could connect with the trail leading to the Presideo and to the end of the San Pedro trail system in Saint David. It is easiest to describe this loop trail going counter clockwise. From the map sign in the parking lot go North a short way along the path to the trail gate. Go through the gate and then ride the trail North. After a short distance there is a sign on the right marking the trail to the Fairbank Cemetery. No bikes are allowed on this trail. After about another mile there is a ruined mill on the right. About a half mile past this you'll come to a junction with a trail leading North down into a big wash. If you wanted to connect with the Presideo trail you would descend the trail to the dry wash. It is a short distance to the river which is usually quite shallow. You would then ford the river and make your way North and West. This is not a clearly marked trail. You would then cross the first abandoned railroad bed you come to and then make your way to the second railroad bed to the West. This is the trail leading North to the Presideo and beyond (see the Presideo Trail). To continue on this ride however just stay on the main trail as it heads West and then follows the San Pedro River South. After about another mile you'll come to an abandoned railroad bridge on your right that leads across the river. It's possible to cross this bridge and connect with the Presideo trails (see the Presidio Trail) but for this ride follow the main trail South along the abandoned railroad bed back to Fairbank. There are some sandy stretches on this section of the trail. Ride through the Fairbank tourist attraction and back to the parking lot to complete the four mile loop.
