This is a short, close to Benson hike that can easily be done in about 2 hours.  The hike is in the San Pedro Riparian National Conservation Area and is managed by the Bureau of Land Management.  When I did the complete loop as indicated on this website my gps unit indicated that the hike was 4.23 miles.  This is a little more than the official markers indicate, but I did add the little loop up to the cemetery.  This is one of the more interesting parts of the hike and should not be avoided.  There are some grave markers but most of the graves are visible as mounds of rocks.  I did the hike in 1 hour and 40 minutes.  The trail begins within the fenced in Fairbank Historic Townsite on the north side.  The Trailhead is marked with a sign and the trail is well marked with informational signs and trail marking signs.  The trail is quite flat except for the little climb up to the cemetery.  The trail is mostly sand and dirt with a minimum of rocks.  So, the footing is generally pretty good.  Much of this trail is wanders through mesquite woods and open grassy meadows.  It is not especially scenic but it does provide good exercise.  The townsite, cemetery, Grand Mill ruins and the San Pedro River overlooks are the interesting things to see.  Due to the water in the San Pedro there can be some good birding in the area.  When I visited in November 2015 there were two Coues Whitetailed Deer in the picnic area.     

There are pit toilets at the parking area.  The parking area close to the trailhead is very small the extended parking area close the AZ 82 is quite large. 

The old school house in Fairbank Historic Townsite also serves as a gift shop.  However, when I visited on a weekday in November nothing was open.
