Have never taken it..Rt 5...I don't remember seeing any signs in Seligman for the turn off....but its probably there.....check to make sure of the condition of the road - there's still some unpaved state rts out there. I just looked at Mapquest, and it doesn't even show SR 5 going all the way thru to Seligman..... maybe call someone in Seligman and ask. I do old Rt 66 from Kingman to almost Ashfork - keeps you off the freeway and its a nice ride, its signed pretty well.
