To get to the Mount Boyce walks turn left at the Blackheath traffic lights, cross the rail line and turn immediately right into Station Street. Continue along Station St. (which turns into a dirt road) for about 3.2km or so until you arrive at Carpark 1 (Mt Wilson GR:464770) indicated by the green dot on the sketchmap below. An alternative is to drive through the traffic lights at Blackheath for about 780metres taking the first turn on your left over the rail overpass bridge and turn right into Station St. Continue to Carpark 1. The dirt road gets a little rough on one downhill section as you go through the open gate.
There are a number of walking tracks in this area other than those indicated on the sketchmap. It's quite a pleasant area to potter around and find the various rockclimbers passes and tracks above the cliffline and enjoy the panoramic views of the Kanimbla Valley.
