Urban caches in parks tend to be fairly easy terrain, safe for little kids to find but not really a satisfying experience for more adventurous geocachers. This location is recycled from a puzzle created and archived when it had all the finds it was going to get. The location is deserving of a cache with an intermittent waterfall and close proximity to interesting rail infrastructure.
There are several routes to ground zero as a glance at a map will reveal. However it is important to note that it is not necessary to trespass on railway land. Darebin Parklands and Rockbeare Park are fascinating areas and although most areas are frequently visited, this little corner has less attention. It would be appreciated if your log could contain your opinion on whether the nearby waterfall, usually dry, is a natural or manmade phenomenon.
