5.9 mile trail near Willcox, Arizona Grant Hill Loop--Mt. Graham is about 5.9 miles long and located near Willcox, Arizona. The trail is great for mountain biking and normally takes 1-3 hours. If you are looking to get out of the low desert heat and do some biking, this is for you.Â Head up Highway 366 which is off US 191 south of Safford and north of Willcox.Â The road is very twisty with lots of switchbacks, but paved for about 18 miles.Â You will pass various campgrounds (Arcadia) and trails (Lady Bug Pass) but continue on to Hospital Flat.Â A nice campground with about 10 walk-in tent only sites.Â Pit toilet but no water.Â Bike from here, about 0.8 miles further up the road to Milepost 138 where the trail head is located on your left.Â The forest service road to the right is the Cunningham Loop which I have not ridden yet. Head clockwise on the trail for the best ride.Â Go slightly up hill, pass through the gate, and then the trail heads downhill for a nice cruise.Â But then it starts up gradually, but at this elevation you will be sucking air.Â About 1 mile into the ride, look for the short side trail which goes out to an overlook where I took the photo for the cover of this trail.Â Great views into Bonita, Fort Grant and the road into Aravaipa Canyon.Â After the overlook, return to the trail which now turns to single track, but continues up.Â Eventually, you reach the junction with the first of 3 bail outs back to the trail head.Â The photo of the trail sign with my bike is that junction.Â Head left on the outside loop which is now double-track again.Â Further along it turns into single track again on the far west side.Â Joins a double track again and watch for the signs to continue on switchbacks off the old fire roads and #2 and #3 bailouts back to the trail head. Great ride and nice mixture of double-track and single track.Â When I rode it was 60 degrees on June 16th--Father's Day. BTW--Ignore the map which shows Arcadia Campground above Hospital Flat.Â The Google Map is wrong.Â Arcadia is far down the mountain not where located on this map.Â Pay attention to the Mileposts and remember that the Grant Hill Loops are at MP 138 and you won't go wrong.Â Hospital Flat is at MP 137 or so.Â I stay in the Lower camp, not the upper camp which is for RVs.
