This cache is on The Skyline which is a very popular walking/riding trail.
You can infact walk to here from the center of Sunbury on a cement path most of the way, via The Nook (Maybe pick up the cache there "The Nook"!) and up the very steep path

to the Skyline Linear reserve.
There are great views along The Skyline : Sunbury, the northern rail bridge, and along a bit further you can see out to Mt Macedon. If you keep going there is of course another Geocache - "Sunbury Bank". The trail does not stop there.... you can in fact walk on to Raes Road which is not too far from where the new train station will be in some years. (part of the Lancefield Road and Sunbury North Precinct Structure Plan).
As always, when warm, watch where you put your feet... there is grass and where this is grass there are snakes!
