The Yangoora Bushland Trail is little used, but easily accessible and goes through some pleasant bushland. It skirts the edge of the little known, but worth visiting, Lane Cove Lake. There are however very few places where the lake can be seen clearly. This cache is in the place with the best views of the lake that I have found (at least on public land). There's a fair bit of wildlife around here - mainly brush turkeys and various lizards. (There will be snakes, but I have not encountered any on this particular stretch.)
The trail goes from Sam Johnson Way to behind the Arise apartment block. The western end has parking (in the Mowbray Road athletics ground). The access from the Arise apartments is from the garden / barbeque area at the back - there's a small black gate (waypoint "01 ARISE"). The trail is easy to find at the other end (waypoint "02 SJW") from a small flight of steps on Sam Johnson Way, just where it meets Epping Road. As to public transport, there are several buses that go from the City up Epping Road and there are stops very close to each end of the trail.
I placed this cache in December 2011. The trail was pretty variable; sometimes well maintained and at others it has seemed to fall into disuse and was almost impassable (which just adds to the fun). In 2013 the old servo was demolished for the building of the Arise apartments. The trail was closed from May 2013 to Feb 2017. On gaining access again, the cache was about a metre behind a newly installed chain-link fence. I replaced the cache with a new one ~10m east and in a very similar location. The trail seems to be well maintained these days.
I would like to acknowledge Leek's archived cache GCHKKY at the other end of the trail and lake; also inspired by Lane Cove Lake. This is great trail and I thought it needed an active GC cache. That cache listing also provides the following history: Lane Cove Lake was "formed by an old dam built by the Cumberland Paper Board Mills in 1913". Recently (July 2016) I found more information on the history, including this 1928 video of fire-fighters in the ruins of the mill after the fire that caused its final closure and this newspaper article about the fire.
The cache is hidden just off the path so there is no need to trample plants. The cache is a ~0.5lt black plastic container.
