Overview: Out and back hike into Bulldog Canyon on Tonto Forrest Road 3554 from Usery Pass Road. FR3554 ends at FR10 so you could extend this hike North or South from the end of this route. The trail is very sandy but not hard going. I was trail running and found the footing to be acceptable, soft in some place. It's mostly a 4x4 or OHV road but there were more horses than motorized vehicles on the trail.
